Top 5 reasons for POST method returning 200 : No Resource Created: If the POST operation doesn't create a new resource but performs an action (e.g., updating data or triggering a workflow), returning 200 OK is appropriate. Example: Submitting a search form or sending an email via a POST request. Legacy Systems or Practices: Some older systems or APIs may not strictly adhere to the spec or use 200 OK for simplicity or out of habit. Lack of Location Header: If the API doesn't return the URI of the newly created resource, some developers opt to return 200 OK instead of 201 Created. Convenience or Consistency: To keep responses uniform across endpoints, developers might default to 200 OK for all success responses, even if 201 Created is more semantically correct. Client Expectations: Some client libraries or systems might expect 200 OK for all success responses and handle 201 Created differently, leading developers to stick with 200 OK.
It depends on server implementation, If the resource doesn't exist, some servers may create a new resource, while others may return an error, such as a 404 Not Found or a 409 Conflict status code. The exact behavior can vary based on the server's configuration and the API design.
You're awesome buddy your explanation is soooooo smooth.....loved it!!
Glad it helps

One question that if I'm doing a put request and the resource is not created then will it create a new resource or throw any error?
