This error message implies that there was a problem with the grammar or structure of the client’s request, such as erroneous or missing parameters, unsupported HTTP methods, or corrupted data.
The client must fix the problem and send a proper request again because the server cannot process the request owing to its flaws. The 400 Bad Request status code aids in diagnosing and locating issues with client-server communication.
HTTP Error Codes 401 Unauthorized
The 401 Unauthorised status code is an HTTP response that shows the client’s request for the requested resource does not contain proper authentication credentials. When a server issues a 401 error, it signifies that in order to access the resource, the client must enter appropriate credentials, often in the form of a username and password.

HTTP Error Codes 403 Forbidden
The client’s request was legitimate, but the server rejected it, as indicated by the HTTP status code 403 Forbidden. A 403 status code basically informs the client that they lack the authorization to access the requested resource when a server responds with one.
There are several potential causes for this, including unsuccessful authentication, insufficient rights, or an intentional restriction put in place by the server administrator. The 403 Forbidden error is a security precaution to safeguard confidential data or stop unauthorized access to specific resources. The client is prompted to reevaluate their request or look for alternative ways to get the needed content.
