Custom Shopify API Integration For Your Store



Got systems that won't talk to your Shopify store? I connect them.

I specialize in custom Shopify API integrations that link your store to the CRMs, payment gateways, and tools you already use, so data flows automatically and your team stops copying things by hand.


What I'll handle for you:


  • Shopify Admin & Storefront API integration
  • Payment, shipping & CRM connections
  • Real-time data sync between platforms
  • Cart & checkout API integration
  • Webhook configuration & event handling
  • Custom backend automation
  • Secure authentication (OAuth, tokens)


I make sure your integration is reliable, well-documented, and easy to maintain long after handover.


Message me before ordering so I can scope your project and confirm feasibility for free.


Tech Stack: Liquid template, GraphQL, Node.js, JavaScript, Express, Shopify Admin API, Storefront API, REST APIs, Webhooks, OAuth.

I'm an API developer who helps businesses connect their tools and automate the work that slows them down. I specialize in API integration and backend automation, linking stores, apps, and platforms with payment gateways, CRMs, and third-party services so your data flows on its own. Every project I deliver comes with clean code, error handling, and clear documentation, so nothing breaks after handover. I'd rather build something reliable than something rushed. Have a project in mind? Message me and let's talk it through.
