Subject: HTTP 405 error - why is my request method not allowed??
Hey guys,
So I’m trying to POST some data to an API, and bam—http 405 error hits me like a truck. "Method Not Allowed"?? Ugh.
I double-checked the URL, and it’s correct. The endpoint *should* accept POST, right? But nope, server’s like "nah, not today."
Anyone else run into this? Is it a backend config issue, or am I just dumb? Lol.
Quick fixes I’ve heard:
- Try GET instead (if that makes sense for the request).
- Check CORS headers if it’s a web app.
- Maybe the server’s just picky af.
Help a dev out—what worked for you?
Thanks! 🍻

Hey! Had the same http 405 error last week. Turns out the server was configured to only accept GET for that endpoint, even though the docs said POST.
Try hitting it with Postman or curl to see what methods are actually allowed. Sometimes the server’s just misconfigured.
Also, check the response headers for "Allow"—it’ll list the accepted methods. Saved me hours of headache!

lol @ "nah, not today" – felt that.
For me, the http 405 error was because of a stupid typo in the URL. Like, one extra slash or missing a path param.
Double-check the endpoint structure? Maybe compare it to the API docs side-by-side.
Also, if it’s a REST API, some frameworks are weird about trailing slashes. Worth a shot!

405’s a pain, man. Could be:
- Server-side route misconfiguration (like, someone forgot to add POST in the backend code).
- Proxy or load balancer blocking it.
Try reaching out to the API maintainers if you can.
Tool rec: Swagger UI or Insomnia to test endpoints visually. Helps rule out client-side issues.

http 405 error usually means the server knows the endpoint but won’t take your method.
Quick thing: are you *sure* the endpoint supports POST? Some APIs have separate URLs for GET vs. POST.
Also, if you’re using fetch/Axios, check for accidental preflight OPTIONS requests messing things up. CORS can be sneaky.

Thanks for all the tips, folks!
Tried the curl test, and yep—POST’s not allowed, but GET works. Guess the docs are outdated.
Weirdly, the "Allow" header wasn’t in the response either. Gonna bug the backend team about it.
Also, Insomnia was a game-changer for testing. Appreciate the recs! 🍻

Bro, same. Mine was a dumb middleware issue.
The backend had some auth layer that was rejecting POSTs unless you had a specific header.
Maybe peek at the network tab in dev tools? The response might hint at what’s missing.

405’s brutal. Here’s what I’d do:
1. Test with curl: `curl -X POST [url]` – see if it’s really the client or server.
2. Check if the server’s returning an "Allow" header (it’ll say GET, POST, etc.).
No header? Probably a backend bug.

http 405 error can also happen if the endpoint’s been deprecated or moved.
Had this with a versioned API—turns out POST was only allowed on /v2/, not /v1/.
Maybe check the API version?

"Method Not Allowed" usually means the route exists but not for your verb.
Try:
- GET (just to see if the endpoint works at all).
- OPTIONS (might reveal allowed methods).
If GET works but POST doesn’t, it’s 100% a backend thing.
