POST /contacts Bad Request

I’m POSTing a new contact to the api, but I get a 400 Bad Request with the following message:

Input could not be converted to a valid request

I tried lots of combinations, but would like to know how I could get some more details about my error.
Is it a problem if the json contains one or two additional fields for the contact object, which are not specified?

Extra fields shouldn’t be a problem. The REST API documentation for Create a Contact outlines the required fields and shows an example. You can even Try The API. See image below.
