I will integrate third party apis and oauth2 into your backend
Hadeed
About this gig
Stuck trying to connect your app to stripe, a third-party platform, or and Oauth2 login flow?This is exactly what I do. I specialize in wiring external APIs into nodejs, expressjs, and nestjs backends - including the parts most tutorial skip: token refresh handling, callback flow bugs, rate limit, and edge cases that only show up in production.
What You Get:
- Oauth2 auntentication flow setup (login,callback, refresh token handling)
- Stripe or other payment gateway integration
- Integration with any documented third-party REST APIs.
- Secure credential handling and token storage
- Debugging of existing broken integrations - not just builds
Recent Work:
I built the Oauth 2 integration layer for a SaaS product that automates proposal submission through and official third-party API, including debugging callback flow issues and fixed silent failures inthe authentication pipeline.
Why Work With Me:
If your integration is half working, throwing silent errors, or you are not sure how to start, send me the details and i'll give you an honest read on what It'll take - before you commit to anything

FAQ
My Oauth integration us already built but broken - can you just fix it?
es, this is one of the most common request I get. Share your repo, and error logs, and I'll diagonse before quoting
Do you handle webhook set up too, or just the initial connection?
Both, webhook handling is included in standard and premium packages, and available as an adds-on on Basic.
What if the third-party API I need isn't listed in your example?
If it has public documentation, I can almost certainly integrate it. Messageme the API docs link before ordering and I'll confirm scope.
