I will fix django jwt, stripe webhook, celery and API errors
Ubaid Ullah
About this gig
Your API integration is failing and users are hitting it?
I'm Ubaid, Python/Django developer (3 years), founder of Djangix. I specialise in the integration errors other devs give up on - I wrote the published fixes for Stripe webhook 400s, JWT 'invalid token / expired' 401s, CORS blocks and CSRF failures.
WHAT I FIX / BUILD:
- JWT auth: invalid token, expired token, 401 errors (SimpleJWT / DRF)
- Stripe webhooks: signature verification 400s, payment events
- Celery / Django Tasks: tasks not running, retries, Redis
- CORS and CSRF errors between frontend and Django
- DRF endpoints: wrong responses, auth, permissions
- Third-party API integration in Django
WHAT YOU GET:
Working, tested fix + a short explanation of the root cause, so it doesn't come back.
Message me FIRST with the error / response you're seeing and your stack (Django + React? plain DRF?). I'll confirm scope and package before you order.

FAQ
My Stripe webhooks return 400. Can you fix that?
Yes — signature verification 400s are my published specialty. Usually it's the raw body, wrong endpoint secret, or middleware order. Basic covers diagnosing and fixing this one error.
Users keep getting logged out / 401 invalid token. Is that JWT?
Usually yes — expired refresh flow, wrong signing key after deploy, or clock / settings mismatch. Send me the exact 401 response and I'll confirm before you order.
Do you work in Stripe live mode?
We fix and test in test mode first. Going live is a final key swap you do with my checklist — I never need your live secret key in chat.
Celery tasks stopped running after deploy — covered?
Yes. Worker not running, Redis connection, and task registration are the usual causes. That's Basic for one error, Standard if the whole task setup needs rebuilding.
