I need a developer who can connect my Freelancer account to Amazon strictly for payment processing. The goal is for funds released on Amazon—whether through Amazon Pay or Seller disbursements—to flow seamlessly into the payment channel I use on Freelancer without manual intervention. Here is what I expect: • A working integration using Amazon’s official APIs (MWS/SP-API or Amazon Pay, depending on feasibility) that authenticates securely and meets Amazon’s compliance requirements. • Confirmation that the integration recognises a completed Amazon transaction and triggers the equivalent “milestone paid” or balance update on my Freelancer profile. • Clear documentation explaining the setup, any keys or webhooks involved, and how to re-authorise the connection if a token expires. • A brief walkthrough (video call or written guide) so I can test a sandbox payment and watch it register correctly on Freelancer. You bring the know-how with REST APIs, OAuth, and webhook handling; I’ll supply the necessary Amazon credentials and Freelancer details. Once everything syncs and a test payment reflects on both platforms, the job is done.
