What Am I Getting “API Error: HTTP 400” Error

In this knowledge-base article, we’ll walk you through the “API Error: HTTP 400” and also discuss the reasons and solutions for the same.

The HyperText Transfer Protocol (HTTP) 400 Bad Request response status implies that the server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).

Let us now discuss the reasons behind this error along with the solutions:

1. The website is under maintenance.
2. The website is not throwing a 200 status code. You can check the status of your website.
3. The website is taking more than 30 seconds to load.
4. The server security or firewall is blocking our API requests. If this is the case then you need to whitelist the IP 134.90.148.114 and the user-agent RankMathAPI/2.0.0; https://rankmath.com. You can do this in the firewall or ask your web hosting provider to help you further.
