I will integrate stripe payments into your backend
Gagan
About this gig
Need Stripe payments, Google login, or another API connected to your backend? I'll integrate it properly, including the edge cases most developers skip.
I'm a backend engineer with 2.5 years building production SaaS for 500+ enterprise customers. I've shipped OAuth 2.0 authentication across an enterprise platform, and built subscription billing and payment webhooks for my own SaaS products with live paying users.
What I can integrate:
- Payments and subscriptions (Stripe, Razorpay, PayPal)
- Login and auth (Google, GitHub, OAuth 2.0, JWT, SSO)
- Webhooks with signature verification and retries
- Email and messaging (SendGrid, Resend, Twilio, Slack)
- Storage and uploads (AWS S3, Cloudinary)
- Any REST or GraphQL API your product needs
Done properly:
- Webhook handling so payments are never missed
- Secure key storage, error handling and retries
- Tested in sandbox before going live
- Full source code and clear setup instructions
Message me with the API you need connected and I'll confirm the scope and timeline.

FAQ
Do I need my own Stripe account?
Yes. You'll use your own Stripe or PayPal account, so you own the payments and the data. I'll set up the integration and guide you through the configuration.
Will you handle webhooks?
Yes. Webhooks are the part most integrations get wrong. I add signature verification, retries and idempotency so no payment or event is ever missed.
Can you work with my existing backend?
Yes. I can add the integration to your current Node.js, NestJS or Express project, or build a small service for it.
Do you test before going live?
Yes. Everything is tested in sandbox or test mode first, including failed payments and refunds, before switching to production keys.
