400 Bad Request: Understanding This Common Error

A 400 Bad Request error occurs when the server returns an HTTP status code of 400, indicating that the request could not be processed due to a client error. This can happen for a variety of reasons, including bad user input or incorrect API endpoint usage.

Why Does a 400 Bad Request Happen?

The 400 Bad Request status code is typically returned by the server when it encounters an invalid request. This can occur due to various factors such as:

• Bad user input: If the client provides invalid or malformed data, the server may respond with a 400 Bad Request.
• Incorrect API endpoint usage: If the API endpoint is used incorrectly or does not exist, the server may return a 400 Bad Request.
• Overloaded or resource-intensive requests: If the client makes multiple requests in rapid succession, the server may respond with a 400 Bad Request due to resource constraints.
