You will get Connect Your App to Any API: OpenAI, Stripe, CRM & More


Project details
Small businesses and founders know which APIs will unlock their next growth lever — AI features, automated billing, CRM sync, shipping — but integrating them properly (with error handling, retries, webhooks, and security) is a specialist job. I take that integration off your plate entirely: scoped, tested, documented, and deployed — usually within a week, not a sprint.
✅ What You Get
Full API integration with error handling, retries & rate-limit management
Webhook setup and event processing (Stripe events, OpenAI streaming, etc.)
Secure credential management — no API keys in your codebase
Background job / queue setup for heavy async tasks (BullMQ / Redis)
Postman collection + Swagger docs for every endpoint built
Integration tests so future changes don't silently break the connection
Handoff call: walkthrough of how it works so your team can maintain it
🛠 Tech Stack
