Delete and POST are not working on API Gateway

I am using the API Gateway. There I have configure severeal requests. Out of these only GET and POST seems to be working. Whwnever I try to hit the Delete or PUT request in POSTMAN App it gives following error:

HTTP Error 405.0 - Method Not Allowed

The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.

Please let me know Why I am facing issue with these requests only

Hello mamerog834 ,

From the error it looks like method is invalid , is it possible to share the API artifact export ?
