Railway 405 Method Not Allowed on POST Requests
Quick answer
A POST sent over plain HTTP is redirected (301) to HTTPS and clients turn it into a GET, causing 405 or 404. Always call your service with https://.
Most likely fix: Use HTTPS explicitly
How to fix it
Try these in order — the most common fix is first.
1. Use HTTPS explicitly
- Make every client, script and webhook use the https:// scheme
- Test: curl -X POST https://your-app.railway.app/api
- Confirm the POST method survives
Did this fix it?
Symptoms
POST requests arrive as GET; the app returns 405 Method Not Allowed or 404.
Why it happens
- Request uses http:// so Railway answers with a 301 redirect
- HTTP clients switch POST to GET when following the redirect
