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

Hey! I ran into the http error 405 reason: method not allowed last week. Turns out, the server was blocking POST requests because of CORS.

Try adding `Access-Control-Allow-Methods: POST` to your server headers. If you're using Node/Express, check your CORS config.

Also, Postman can sometimes cache old headers—clear that or try a fresh request.

Hope that helps!
