I'm developing an application with authentication, and i need to provide a appropriate status code if there is any error when registering an user, for example a database-related error.

I've been researching but i haven't found an appropriate status code.

CodePudding user response：

The purpose of all HTTP errors is to communicate the operation failed. To pick the right HTTP error, you need to know why it failed.

"database-related error" sounds like a server-side bug or problem, so this is likely just a 500.

CodePudding user response：

You should use the 403 error code

https://en.wikipedia.org/wiki/HTTP_403

From the documentation :

Error 403: "The server understood the request, but is refusing to authorize it." (RFC 7231)[1]

This is the most fitting status code regarding the purpose you want.
