Getting HTTP Error 405 Reason: Method Not Allowed – How Do I Fix This? or Why Am I Seeing HTTP Error

This error’s a pain. http error 405 reason: method not allowed often means the server’s route isn’t set up for POST.

If you’re using Flask/Django, check your `@app.route` decorator—maybe it’s missing `methods=['POST']`.

Or, if it’s a third-party API, their docs might be outdated. Try reaching out to support.
