API & Payment Integrations

Stripe, payment providers, Google Maps, communication APIs, AI services, and third-party SDK integrations.

What this service covers

External providers introduce asynchronous states, retries, version changes, and failure modes. I isolate those concerns behind application-owned interfaces so the product can handle pending operations, duplicate callbacks, provider downtime, and future replacements.

What I provide

  • Provider evaluation and integration plan
  • Client and server integration
  • Payment and webhook state handling
  • Failure, retry, and duplicate-event behavior
  • Secure configuration guidance
  • Integration documentation

Typical delivery process

  1. 1

    Map the provider lifecycle and ownership boundaries

  2. 2

    Define application states before calling the SDK

  3. 3

    Implement idempotency, validation, and recovery

  4. 4

    Test sandbox, failure, callback, and production configuration
