API builder : It’s fixed. Now you will get 400. API User : But that’s wrong too.
API builder : Now what’s your problem.
API User : Send 400 when data is not syntactically correct.
API builder : What does that even mean.
API User : Let me elaborate.
API User : In order to create a user I’m sending the user data in JSON format. Right ?
API builder : Right.
API User : And the JSON that I’m sending is valid JSON. Right ?
API builder : Right.
API User : Then you can’t send 400. Because 400 should be returned when the data itself is malformed.
API builder : I see. So if the payload is not valid JSON then I could send 400.
API User : Right.
API User : If the API accepts xml and the xml is not well-formed then you can send 400.
API builder : Got it.
API builder : So what status code I should send in your case when email is taken.
API User : Let’s talk about it tomorrow.
