Ugh, http status 405 is the worst.
First thing I’d do is verify the endpoint URL. Sounds dumb, but I’ve wasted hours because of a typo.
Next, check if the server expects a trailing slash or not. Some APIs are weirdly strict about that.
If all else fails, curl is your friend:
```
curl -X POST -H "Content-Type: application/json" -d '{"key":"value"}' https://your-api.com/endpoint
```
