About this gig

Are you blocked by Amazon SP-API developer onboarding, expired OAuth tokens, or broken Shopify webhooks?

I provide fast, production-ready API configuration, authentication setups, and automated endpoint integrations for Shopify and Amazon sellers.


What I Do:

  • Amazon SP-API Onboarding: Solution Provider Portal setup, IAM roles, LWA credentials, and token generation
  • Secure Authentication: OAuth 2.0 workflows, automatic refresh token rotation, and Postman validation
  • Shopify GraphQL Integration: Migration from deprecated REST endpoints to modern GraphQL Admin schemas
  • Real-Time Webhooks: Serverless AWS Lambda and Laravel listeners for orders, stock updates, and tracking
  • Bug Diagnosis: Fixing HTTP 429 throttling, payload mismatches, and failed sync calls


Why Work With Me?

  • Fast 24 to 48-hour turnarounds on urgent blockers
  • Clean, maintainable Python and PHP code
  • Full sandbox verification prior to live launch


Message me now to resolve your API issues and get back to selling!
