I will integrate rest apis webhooks oauth or payment gateways


About this gig
Connect your application to a third-party service with a reliable, production-ready integration.
I have integrated carrier, payment, identity, CRM, e-commerce, messaging, telephony, and internal business APIs across Laravel/PHP, Node.js/TypeScript, and Python systems.
I can help with:
- REST or SOAP APIs
- OAuth 2.0, API keys, JWT, and secure token handling
- Webhooks, callbacks, signatures, retries, and idempotency
- Stripe/payment gateways, CRM, e-commerce, SMS, email, and telephony
- Data mapping, validation, logging, queues, and error recovery
- API documentation, tests, versioning, and performance
The package price assumes usable documentation and valid client-owned credentials. Undocumented APIs, many endpoints, data migration, or reverse engineering require a custom offer. Message me first with the provider, workflow, documentation link, existing stack, and desired result.

FAQ
What information do you need for an API integration?
Please send the API documentation, sandbox credentials, required endpoints, sample payloads, authentication method, webhook behavior, mapping rules, test cases, and target environment.
How do you handle OAuth, webhooks, and failed requests?
As scope requires, I implement secure token lifecycles, webhook signature verification, idempotency, retries with backoff, structured logging, monitoring hooks, and safe error handling.
Can you integrate an API into an existing codebase?
Yes. I review the current stack, dependencies, conventions, deployment flow, and test setup first. If hidden technical debt or a larger scope appears, I explain it before expanding the work.
