I will do shopify api checkout webhook payment integration shopify backend whop app dev
Hi, I'm [David], a Shopify Liquid & API developer specializing in custom checkout, backend fixes, and Shopify-Whop integration.
If your store needs a custom checkout, a working webhook, a payment integration that doesn't break, or a smooth Shopify-to-Whop connection for memberships and digital products, I build it clean and fast.
What I deliver:
- Custom Shopify checkout & checkout UI customization
- Shopify API & webhook integration
- Payment integration & gateway fixes
- Shopify backend development & bug fixes
- Custom Shopify app & custom Liquid code
- Headless Shopify setup
- Shopify to Whop store, membership & digital product integration
- Shopify Plus & B2B checkout extensions
I'm a Shopify expert and developer who treats every store like it's my own - secure, scalable, and conversion-focused. Clear communication and clean code on every order.
Launching a new store, fixing a broken integration, or connecting Shopify to Whop for the first time - I'll get it done right.
Message me before ordering to discuss your project, or click "Order Now" and let's get your store running exactly how it should.

FAQ
Do you work with Shopify Liquid code directly, or only apps/plugins?
Yes I write and edit custom Liquid code directly for full control over your theme, checkout, and backend logic.
Can you connect my Shopify store to Whop?
Yes, I build Shopify-to-Whop integrations for memberships, digital products, and store setup.
Do you fix existing bugs, or only build new features?
Both. I take on bug fixes, broken integrations, and API/webhook errors, as well as new custom builds.
What payment integrations can you set up or fix?
I handle custom payment gateway integration and checkout payment issues, including custom Shopify Checkout extensions.
Is Shopify Plus required for custom checkout work?
Not always — some custom checkout work needs Shopify Plus (for full checkout.liquid access), but many fixes work on standard plans. Send your store link and I'll confirm.
What do you need from me to start?
Store admin access (or collaborator access), a clear description of the issue or feature, and any relevant API keys or Whop credentials if integration is involved.
How fast can you turn around a basic fix?
Basic Liquid/API/webhook fixes are typically delivered within 2 days.
Do you offer ongoing Shopify backend support?
Yes, ongoing support and maintenance can be arranged after the initial project — message me to discuss a custom plan.
Can you build a custom Shopify app from scratch?
Yes, custom app development is included in the Premium package, covering both storefront and backend functionality.
What if I need revisions after delivery?
Each package includes revisions (1 Basic, 2 Standard, 3 Premium) to fine-tune the checkout, API, or integration until it's exactly right.
