What is an HTTP Error 400 (Bad Request)?
An HTTP Error 400 (Bad Request) is a type of web server error that occurs when the server cannot understand or interpret a client request. This can happen for various reasons, such as invalid data, incorrect usage of URL parameters, or mismatched expectations between the client and server.
Common Causes of HTTP Error 400 (Bad Request):
- Invalid or missing required parameters in a URL or query string.
- Insufficient permissions or access rights to perform the requested action.
- Duplicate or malformed data sent by the client.
- Mismatched expectations between the client and server, such as different request methods (e.g., GET vs. POST).
