REST API Design & Integration
Versioned, documented REST APIs your mobile & partner apps will love.
I design REST APIs from schema to deployment: versioning strategy, OAuth2 / Sanctum auth, rate limiting, idempotency, webhooks, background workers and full Swagger / OpenAPI documentation. I integrate payment providers, CRMs, ERPs, shipping and messaging systems with retry, logging and observability baked in.
What's included
- Versioned REST endpoints with OpenAPI docs
- OAuth2 / Sanctum / JWT authentication
- Webhooks with signature verification & retries
- Rate limiting, idempotency keys & audit logs
- Third-party integrations (Stripe, LiqPay, Novaposhta, HubSpot, etc.)
- Postman collections for QA & partners
