Contacts API v1 - 415 Unsupported Media Type errors for requests missing the Content-Type header
Jun 2, 2020 3:43 PM
Last week, we made some infrastructure upgrades to the Contacts API. While this upgrade was mostly transparent, and didn't change the functionality of the API, this did change how the Content-Type request header is handled.
While we've always listed the Content-Type header as a requirement, this wasn't previously enforced, so requests without that header could still succeed. As of last week, this header requirement is now being enforced, and any POST or PUT requests that do not include this header will result in a 415 Unsupported Media Type error.
If the request library that you're using doesn't automatically include the content-type header, you'll need to manually include it. Since this issue only affects the v1 version of the Contacts API, the header will need to be set to "Content-Type: application/json; charset=utf-8"
