Shopify Create Checkout: 7 Powerful Ways to Boost Success 2025

Understanding Shopify’s Checkout Process and APIs

Shopify create checkout is the process of programmatically initiating a checkout flow using Shopify’s APIs. If you’re looking to implement this functionality, here’s what you need to know:

• Current Approach (2024): Use the Storefront Cart API with GraphQL to create checkouts
• Deprecated Method: The Checkout API (being phased out by April 2025)
• Basic Implementation: Send a POST request to /api/graphql.json with a cartCreate mutation
• Requirements: Public app with write_checkouts scope and valid storefront access token

Shopify’s checkout system is the backbone of e-commerce transactions, processing over 5.5 billion orders globally and trusted by more than 644 million customers worldwide. As a merchant or developer, understanding how to create and customize the checkout experience is crucial for maximizing conversions and providing a seamless shopping experience.

The checkout process is where digital window-shoppers transform into paying customers, making it one of the most critical touchpoints in your e-commerce journey. With Shopify’s checkout converting up to 36% better than competitors and Shop Pay increasing conversion rates by up to 50% compared to guest checkout, optimizing this experience directly impacts your bottom line.

Shopify Checkout 101: Architecture & Flow

Ever wonder what makes Shopify’s checkout so powerful? It’s not just another payment page—it’s a conversion powerhouse that drives approximately 10% of all US e-commerce transactions. Shopify create checkout systems are built to handle massive traffic spikes (up to 40,000 checkout starts per minute per store!), making them reliable even during the busiest shopping events like Black Friday or Cyber Monday.

The beauty of Shopify’s checkout lies in its simplicity. When your customer shops, they follow a natural path:

They add products to their cart, click to checkout, provide their email and shipping details, review their order, complete payment, and receive confirmation. Nothing complicated—just a smooth journey from browsing to buying.

One of the most brilliant features is Shopify’s one-page checkout option. Instead of forcing customers through a multi-page obstacle course (which we know increases abandonment), everything happens on a single screen. This matters tremendously when you consider that about 70% of online shopping carts are abandoned, with complicated checkout processes being a primary reason shoppers bail out.

As a merchant, you have full control over your checkout experience. Just head to your Checkout settings in the Shopify admin panel to customize everything from email collection methods to form fields and visual appearance.

At Blackbelt Commerce, we’ve seen how checkout optimization can transform conversion rates—often boosting them by 15-20%. For deeper insights on maximizing your checkout performance, check out our guide on Checkout On Shopify: How To Increase Conversions.

Inventory & Payment Lifecycle

Shopify’s checkout doesn’t just collect payments—it intelligently manages your inventory throughout the entire purchase process.

Here’s what happens behind the scenes: When a customer moves through checkout, their selections are continuously verified against your available inventory. The system only places a temporary hold on inventory when payment information is submitted—not before. If a payment fails, that hold is immediately released until the customer tries again. Once payment succeeds, inventory is permanently allocated to the order.

This smart approach prevents you from overselling products while also avoiding unnecessary inventory holds on abandoned carts. The entire payment process includes sophisticated fraud analysis and bot protection, creating a secure environment for both you and your customers.

Speaking of protection, Shopify create checkout includes built-in safeguards against checkout abuse. This is especially valuable if you sell limited-edition items or run flash sales where automated bots might try to snatch up your inventory.

Express & One-Click Options

The moment of truth in e-commerce is the payment step—and this is where one-click checkout options shine by dramatically reducing friction. Shopify offers several express checkout solutions that can transform your conversion rates:

Shop Pay, Shopify’s proprietary one-click checkout, delivers impressive results—lifting conversion by up to 50% compared to guest checkout. The numbers speak for themselves: Shop Pay checkouts convert at 1.72 times the rate of regular checkouts, and customers who use Shop have a 9% higher repurchase rate.

Beyond Shop Pay, your customers can enjoy PayPal One Touch for seamless purchases without re-entering credentials, Meta Pay (formerly Facebook Pay) which leverages payment information saved across Facebook, Instagram, and WhatsApp, and Apple Pay/Google Pay for biometric-secured one-tap checkout on mobile devices.

The mobile optimization is particularly crucial considering that 65.7% of all e-commerce retail sales in 2022 happened on mobile devices. Even more interesting—simply displaying Shop Pay as an option can increase lower-funnel conversion by 5%, even if customers don’t use it!

Implementing these express checkout options is straightforward, but the impact on your bottom line can be remarkable. When we help clients optimize their Shopify create checkout experience at Blackbelt Commerce, these one-click options are always part of our conversion strategy.

How to shopify create checkout with the Storefront Cart API

Ready to create a checkout experience that converts? In 2024, the Storefront Cart API with GraphQL is your go-to solution for programmatically creating checkouts in Shopify. This modern approach replaces the older Checkout API that’s riding off into the sunset by April 2025.

Why should you care about the Storefront Cart API? It’s simply better in every way:

First, it’s smarter with your data. GraphQL lets you request exactly what you need in a single call – no more, no less. This means faster load times and happier customers.

Second, it works everywhere your customers shop – whether they’re browsing on their laptop, scrolling on their phone, or shopping through any other channel.

Third, you can say goodbye to rate limit headaches. The API handles legitimate traffic without limits while still keeping the bad bots at bay.

Fourth, you get the whole package – full support for discounts, product bundles, subscription products, and all the features that make modern e-commerce tick.

Finally, it plays nicely with Shopify’s Web Checkout and UI extensions, giving you a unified experience across your store.

Here’s what a basic shopify create checkout request looks like using the Storefront Cart API:

graphql
mutation cartCreate($input: CartInput!) {
cartCreate(input: $input) {
cart {
id
checkoutUrl
lines(first: 10) {
edges {
node {
id
quantity
merchandise {
... on ProductVariant {
id
title
}
}
}
}
}
}
}
}

This mutation creates a cart with your specified items and returns a checkoutUrl that you can redirect your customers to. They’ll land right on a checkout page with their items ready to go.

Prerequisites & Authentication for shopify create checkout

Before you jump into creating checkouts, there are a few things you’ll need to have in place:

You’ll need a public app – this is non-negotiable. Unlike the older API, private or custom apps won’t work here. Your app needs to be registered as public in Shopify.

Next, you’ll need a storefront access token to authenticate your requests. You can generate this in your Shopify admin by navigating to Apps > Develop apps > [Your App] > API credentials > Storefront API.

Your app must have the write_checkouts scope granted by the merchant. Without this permission, you’ll hit a wall with the error: [API] This action requires merchant approval for write_checkouts scope.

All your requests should be sent to your store’s GraphQL endpoint: https://[store-name].myshopify.com/api/2023-10/graphql.json

Authentication is straightforward – just include your storefront access token in the request headers:

X-Shopify-Storefront-Access-Token: your_storefront_access_token

At Blackbelt Commerce, we’ve guided countless merchants through this transition from the older Checkout API to the Storefront Cart API. Our clients maintain their sales momentum without missing a beat during the switch.

Step-by-Step cartCreate Walk-Through

Let’s break down the process of creating a checkout with the Storefront Cart API into digestible steps:

Step 1: Prepare your mutation

This is where you tell Shopify what you want to create:

graphql
mutation cartCreate($input: CartInput!) {
cartCreate(input: $input) {
cart {
id
checkoutUrl
estimatedCost {
totalAmount {
amount
currencyCode
}
}
}
userErrors {
field
message
}
}
}

Step 2: Define your variables

Here’s where you specify the products, customer info, and any discount codes:

json
{
"input": {
"lines": [
{
"quantity": 1,
"merchandiseId": "gid://shopify/ProductVariant/12345678901234"
}
],
"buyerIdentity": {
"email": "[email protected]",
"countryCode": "US"
},
"discountCodes": ["SUMMER2024"]
}
}

Step 3: Send the request

Make a POST request to your store’s GraphQL endpoint with the right headers:

POST https://your-store.myshopify.com/api/2023-10/graphql.json
Content-Type: application/json
X-Shopify-Storefront-Access-Token: your_storefront_access_token

Step 4: Process the response

Shopify will respond with a checkoutUrl that’s ready for your customer:

json
{
"data": {
"cartCreate": {
"cart": {
"id": "gid://shopify/Cart/c1-12345678901234",
"checkoutUrl": "https://your-store.myshopify.com/checkout?cart=c1-12345678901234",
"estimatedCost": {
"totalAmount": {
"amount": "29.99",
"currencyCode": "USD"
}
}
},
"userErrors": []
}
}
}

Here’s how the Storefront Cart API stacks up against the older REST Checkout API:

Feature	REST Checkout API	Storefront Cart API
API Type	REST	GraphQL
Status	Deprecated (ends April 2025)	Current
Rate Limits	Yes	No (for legitimate traffic)
Stackable Discounts	No	Yes
Webhooks	Yes	No (use order webhooks instead)
Shopify Functions Support	No	Yes
Query Efficiency	Multiple requests needed	Single request possible

Payments, 3-D Secure & Enabling Shop Pay

When implementing shopify create checkout, payment processing deserves special attention, especially if you’re building a headless storefront with custom payment handling.

For European merchants (or anyone selling to European customers), 3D Secure authentication is a must-have under PSD2 regulations. Shopify makes this process smooth with a clear workflow:

When a payment needs 3D Secure verification, Shopify provides a nextActionUrl in the Payment object. Your application should then guide the customer to this URL to complete their authentication challenge. After they’ve authenticated, you’ll need to check in with the Payment object periodically until its ready status turns to true. Once that happens, you can wrap up the checkout process.

Enabling Shop Pay and other express checkout options is a breeze:

Simply head to your Shopify admin, steer to Settings > Payments > Manage, and flip the switch to enable Shop Pay. For Apple Pay, Google Pay, and other wallet options, you’ll find them under the Wallets or Additional Payment Methods sections.

We’ve seen remarkable results at Blackbelt Commerce after implementing Shop Pay for our clients. Mobile shoppers convert up to 40% more often, while desktop users show a 25% bump in conversion rates. These aren’t just numbers – they’re real revenue gains for businesses just like yours.

Migrating from Deprecated Checkout API to Storefront Cart API

Important alert: The Checkout APIs on both the REST Admin API and Storefront API are being deprecated as of API version 2024-04 and will be completely shut down on April 1, 2025.

If you’re currently using the Checkout API to shopify create checkout, you need to start planning your migration now. I can’t stress this enough—April 2025 might seem far away, but updating your integration takes time, and you definitely don’t want to scramble at the last minute!

The good news? This migration isn’t just busy work. Moving to the Storefront Cart API brings several meaningful improvements to your checkout experience. You’ll enjoy more efficient GraphQL queries instead of multiple REST calls. You’ll say goodbye to those frustrating rate limits for legitimate traffic. Your customers will appreciate the ability to stack discount codes. And you’ll gain access to Shopify Functions for executing custom business logic right within the checkout flow.

The only exception to this migration requirement is for abandoned checkouts, which will remain accessible through the Admin API. For everything else, it’s time to make the switch.

For step-by-step migration guidance, check out Migrate to the Storefront Cart API and stay informed with the official Checkout APIs will be shut down April 1, 2025 announcement.

Difference Matrix & Feature Parity

When we help our clients at Blackbelt Commerce migrate between these APIs, the first question is always: “What’s actually changing?” Let’s break it down with a clear comparison:

Feature	Checkout API	Cart API	Notes
API Style	REST & GraphQL	GraphQL only	Cart API offers more efficient data fetching
Webhooks	checkout/create, checkout/update	None	Subscribe to order creation webhooks instead
Gift Cards	Can append to checkout	Not supported	Alternative approaches needed
Carrier-Calculated Shipping	Supported	Not supported	Use standard shipping rates
Cart Persistence	Checkouts queryable after completion	Carts deleted upon order creation	Rely on order webhooks for completed orders
Discounts	Limited stacking	Full support for stackable discounts	Better promotion capabilities
Functions	Limited	Full support	Improved customization options

The most significant changes involve how you’ll track order completion (since carts disappear once an order is created) and the approach to shipping calculations. But in our experience, most merchants find the benefits—especially around discount handling and performance—well worth the effort of migration.

Migration Checklist

Let’s make this transition as smooth as possible with a practical checklist. I’ve helped dozens of merchants through this process, and here’s what works:

Start by auditing your current implementation. Take inventory of everywhere you’re using the Checkout API—both the endpoints and the specific data you’re requesting. This gives you a clear picture of what needs changing.

Next, refactor your API calls systematically. You’ll replace checkoutCreate with cartCreate, update checkoutLineItemsAdd with cartLinesAdd, and modify address updates accordingly. Take it one endpoint at a time to avoid overwhelming your team.

Don’t forget to update your authentication. The Cart API requires the write_checkouts scope and a valid Storefront access token. Authentication issues cause the most headaches during migration, so verify these early.

Perhaps the biggest mindset shift is adapting to the new cart lifecycle. Since carts vanish upon order creation (unlike checkouts), you’ll need to subscribe to order creation webhooks and rethink how you track completed purchases.

Testing thoroughly is non-negotiable. Test every cart operation in your development environment before going live. Pay special attention to discount application, shipping calculations, and tax handling.

Finally, consider a gradual rollout if possible. Running both APIs in parallel initially gives you a safety net while you iron out any issues.

Common Pitfalls & Fixes

After helping numerous merchants with this migration, I’ve noticed some recurring challenges. Here’s how to avoid them:

Missing webhooks for cart events catches many developers by surprise. Unlike the Checkout API, the Cart API doesn’t provide webhooks for cart creation or updates. The solution? Implement client-side tracking and rely on order creation webhooks instead.

Abandoned cart recovery requires a new approach since completed carts disappear. You’ll need to either implement your own tracking system or continue using Shopify’s abandoned checkout endpoints (which will remain available).

Token mismatches create frustrating errors that can be hard to diagnose. Implement proper token refresh mechanisms and robust error handling to avoid customer-facing issues.

Shipping rate calculation works differently in the Cart API. Since carrier-calculated shipping isn’t supported in the same way, you’ll need to use standard shipping rates or build a custom calculator.

Merchandise ID format trips up even experienced developers. The Cart API requires the Global ID format (gid://shopify/ProductVariant/[id]), so double-check all your product references.

By anticipating these common issues, you’ll save yourself hours of troubleshooting and ensure your customers enjoy a seamless checkout experience throughout the transition.

Customizing & Extending Checkout Safely

Gone are the days of risky checkout.liquid customizations! Shopify has acceptd a more structured approach called Checkout Extensibility that lets you create beautiful, branded checkout experiences without worrying about breaking things when Shopify updates their platform.

Think of Checkout Extensibility as a safety net for your creativity. It gives you powerful tools to make your checkout uniquely yours while Shopify handles all the technical heavy lifting behind the scenes.

The framework consists of four main pillars:

1. UI Extensions: Add your own custom elements exactly where you need them in the checkout flow
2. Shopify Functions: Extend what happens behind the scenes with custom business logic
3. Branding API: Make checkout look and feel like your brand
4. Web Pixel Extensions: Keep track of what shoppers do throughout checkout

The beauty of this approach is that your customizations won’t break when Shopify rolls out new features. We’ve seen too many merchants struggle with broken checkouts after updates when using the old checkout.liquid approach. This new framework eliminates that headache entirely.

Want to dive deeper into implementing these extensions? Visit Apps in checkout for the technical details. And if you’re just getting started with responsive checkout design, our guide on Shopify’s Responsive Checkout: A Beginner’s Guide will get you up to speed quickly.

Visual Branding & UI Extensions

Your checkout should feel like a natural extension of your store, not a jarring third-party experience. That’s where UI extensions and the Branding API come in.

With UI extensions, you can seamlessly add custom elements throughout the checkout journey. Want to show a trust badge before payment? Add a special offer on the shipping page? Collect birthday information for your loyalty program? All possible with UI extensions at specific attachment points.

The Checkout Branding API lets you infuse your brand’s personality into every visual aspect of checkout:

Colors and typography that match your website create a seamless experience. Button styles and corner radii maintain your visual language. Even form fields and headers can reflect your brand’s unique style.

If you’re on Shopify Plus, you’ll love the drag-and-drop checkout editor that makes these changes possible without writing a single line of code.

We’ve implemented these customizations for brands like Judith Leiber and the Lakers Store, creating checkout experiences that feel like a natural extension of their brand. Customers trust familiar experiences, and that trust translates directly to completed purchases.

Functional Extensions & Upsells

Beyond just looking good, your checkout can work smarter with functional extensions that boost your bottom line.

Shopify Functions let you implement custom logic for critical business processes. Create sophisticated discount rules that target specific customer segments. Define shipping options based on complex criteria. Route payments through different gateways depending on the order. The possibilities are extensive.

Post-purchase extensions are where the magic happens for increasing order value. These appear after the customer has already paid but before they see the order confirmation. It’s the perfect psychological moment to offer complementary products or services. We’ve seen these extensions increase average order value by 15-25% for our clients.

Some of our favorite checkout-enhancing apps include CartHook for post-purchase upsells, Ultimate Special Offers for one-click additions, Bold Upsell for smart product recommendations, ReCharge for subscription management, and Swell for integrating loyalty programs.

The best part? All these extensions work within Shopify’s framework, so you maintain full security and compatibility with future updates.

Security, Compliance & Performance

When it comes to checkout, security isn’t optional—it’s essential. Fortunately, Shopify’s extension framework maintains strong security guardrails.

All checkout extensions run in a secure sandbox environment, isolating them from sensitive payment data. This approach ensures PCI DSS compliance remains intact regardless of your customizations. The platform’s built-in bot protection also helps shield your store from fraudulent activities and checkout abuse.

Beyond security, your checkout needs to meet various compliance requirements. This includes GDPR-compliant data collection practices, ADA accessibility standards for users with disabilities, and adherence to local tax and regulatory requirements that vary by region.

Performance matters tremendously at checkout. A slow checkout is an abandoned checkout. Keep these best practices in mind:

Keep pages lightning fast with a target load time under 2 seconds. Optimize for mobile first since nearly two-thirds of e-commerce happens on phones and tablets. Use touch-friendly buttons (minimum 48×48dp with 8dp spacing) that are easy to tap accurately. Limit network requests from your extensions to maintain speed.

At Blackbelt Commerce, we thoroughly test all checkout customizations for performance impact before deploying them. Even the most beautiful checkout won’t convert if it’s frustratingly slow.

By balancing aesthetics, functionality, security, and performance, you can create a checkout experience that not only looks great but also converts browsers into buyers—safely and reliably.

Troubleshooting & Best Practices

Let’s face it – even the smoothest checkout implementations can hit a few bumps along the way. When setting up shopify create checkout functionality, you might encounter some challenges that leave you scratching your head. Don’t worry, we’ve seen it all before!

One of the most common headaches is the dreaded missing scope error. If you see [API] This action requires merchant approval for write_checkouts scope, your app simply needs the proper permissions. Your app must be registered as a public app with the write_checkouts scope granted by the merchant – a simple fix that saves hours of frustration!

GraphQL errors can be particularly tricky. Those 400 Bad Request responses when sending mutations often come down to syntax issues or missing required fields. I always recommend double-checking your mutation structure against Shopify’s documentation before pulling your hair out troubleshooting.

Inventory management issues can create real customer service nightmares. If you’re seeing orders being created for items that should be out of stock, make sure you’re checking inventory status before creating cart lines. Adding proper error handling for these scenarios will save you countless apologetic emails to customers.

3D Secure authentication failures are becoming more common as payment security tightens globally. If payments are failing during this step, revisit your implementation of the Payment Authentication workflow, particularly how you’re handling redirects and polling for completion status. Getting this right is crucial for European transactions.

While the Cart API doesn’t have explicit rate limits for legitimate traffic (a nice improvement over the older API), implementing smart backoff strategies for failed requests is still good practice. This prevents your integration from hammering Shopify’s servers if something goes wrong.

Error Glossary & Quick Fixes for shopify create checkout

When troubleshooting checkout issues, having a quick reference for common errors can save precious development time:

Error	Cause	Solution
This action requires merchant approval for write_checkouts scope	Missing OAuth scope	Register as a public app and request the write_checkouts scope
Access token is invalid or has expired	Authentication issue	Generate a new storefront access token
Resource not found	Invalid merchandiseId	Ensure you’re using the correct Global ID format
Cart not found	Attempting to access a deleted cart	Carts are deleted after order creation; use order endpoints instead
Invalid input	Malformed GraphQL request	Validate your query structure and variable types
Rate limit exceeded	Too many requests	Implement exponential backoff and request batching

I’ve personally seen dozens of implementations struggle with the Resource not found error because developers forget to use the proper Global ID format for product variants. It’s always the little things!

Security & PSD2 Essentials

Payment security isn’t just nice to have – it’s absolutely essential for modern e-commerce. When handling payments through shopify create checkout, there are several critical considerations to keep in mind.

3D Secure authentication has become increasingly important, especially for European merchants. Required under PSD2 regulations for many European transactions, this process involves redirecting customers to their bank for verification. The key to implementing this smoothly is properly handling the nextActionUrl provided by Shopify and implementing polling to check when authentication is complete. Your customers will appreciate a seamless experience rather than being left wondering if their payment went through.

When it comes to handling payment information, I can’t stress this enough: never handle raw credit card data in your application. Instead, use Shopify’s card vault or third-party tokenization services. This approach not only protects your customers but also simplifies your PCI compliance requirements. Remember to implement proper error handling for any tokenization attempts that fail – customers deserve clear feedback when something goes wrong.

For European merchants, Strong Customer Authentication (SCA) requirements add another layer of complexity. Transactions over €30 in the European Economic Area require additional verification steps. Make sure your checkout flow can gracefully handle these challenges without frustrating customers.

At Blackbelt Commerce, we’ve guided countless merchants through these security considerations. In fact, one of our clients saw their chargebacks drop by 65% after we implemented proper 3D Secure handling in their checkout flow. Getting security right isn’t just about compliance – it directly impacts your bottom line by building customer trust and reducing fraud.

Frequently Asked Questions about Shopify Checkout APIs

What happens if I don’t migrate before 2025-04?

The clock is ticking on the Checkout API, and this isn’t just another routine update. If your store still relies on the deprecated Checkout API after April 1, 2025, your checkout functionality will simply stop working. Imagine losing the ability to process orders right in the middle of a busy sales day!

We’ve helped dozens of merchants through this transition, and I can tell you that the sooner you start planning your migration, the smoother it will go. Depending on how deeply you’ve integrated the Checkout API into your systems, this could be a straightforward update or a more substantial project requiring careful planning.

Think of it like replacing the foundation of your house while you’re still living in it – it takes coordination and expertise to do it without disrupting your daily life (or in this case, your sales).

Can I still use checkout.liquid with new extensions?

I’m afraid the answer is no – checkout.liquid customizations are going the way of the dinosaur. After August 13, 2024, checkout.liquid will no longer be supported for in-checkout pages, which means any customizations you’ve made using this method will stop working.

The good news? Shopify’s new Checkout Extensibility framework offers more powerful, upgrade-safe ways to customize your checkout. To get ahead of this change, run the Checkout Extensibility customizations report in your Shopify admin. This handy tool will identify all your current customizations and help you plan a migration strategy.

You’ll need to replace those checkout.liquid customizations with a combination of UI extensions, Shopify Functions, and Branding API implementations. At Blackbelt Commerce, we’ve guided numerous merchants through this transition, ensuring their checkout experience remains seamless throughout the process.

How do I enable one-click checkout options like Shop Pay?

Setting up one-click checkout options is surprisingly simple, and the payoff is huge! To enable Shop Pay and other express checkout options:

1. Steer to your Shopify admin
2. Go to Settings > Payments > Manage
3. Toggle on Shop Pay and save your changes
4. For Apple Pay and Google Pay, find them under Wallets or Additional Payment Methods and enable them too

Once activated, these options will automatically appear during checkout for eligible customers. The impact can be dramatic – we’ve seen Shop Pay increase conversion rates by up to 50% compared to standard guest checkout across our client base.

This simple change can have a profound effect on your bottom line. One of our clients in the fashion industry saw their mobile conversions jump by 38% within just two weeks of enabling Shop Pay. It’s particularly effective for repeat customers and mobile shoppers who appreciate the streamlined experience.

These accelerated checkout options work best when combined with a well-designed, mobile-optimized store theme and strategic product recommendations. The entire purchase journey matters, not just the final payment step.
