About this gig

Having a Shopify payment, checkout, Whop, API, or webhook issue? I can diagnose the problem, fix the error, and test the complete workflow.


I specialize in Shopify payment bug fixing, checkout troubleshooting, Whop checkout API integration, Shopify API integration, webhooks, and third-party payment/API connections.


My services include:

  • Shopify payment and checkout bug fixes
  • Shopify payment gateway troubleshooting
  • Whop checkout API integration
  • Shopify API and GraphQL integration
  • Webhook setup, testing, and debugging
  • Payment and order data synchronization
  • Third-party API integrations
  • Checkout and payment workflow troubleshooting
  • Custom Shopify API integrations
  • Automated order and fulfillment workflows.


I focus on finding the root cause instead of applying temporary fixes. I will troubleshoot the issue, implement the solution, test the workflow, and verify the integration.


If your Shopify checkout is failing, payments are being rejected, Whop data is not syncing, webhooks are not triggering, or an API integration is returning errors, send me the details.

Please message me before ordering so I can review your requirements and recommend the right package.
