What is the best way to return successful requests and errors in REST API?

Question

JSON

How are the latest fashion trends about what response format should be in a REST API? I know there is no standard. For example, is it worth returning "code: 422 / http code 200", or is it better to return it only as http 422 and return arrays of errors in json? And in general, in general, how is it generally better to return successful requests and errors? How are you doing?

Answer 1

How is this not a standard? There is. If successful, return code 200 in the header and in the data body in the format that the client expects. In case of an error, the error code and text of the error message.
