When an HTTP request to the API is malformed a response with a
code is returned.
The request is invalid. If you attempted to modify or create a resource it’s possible the request body contains invalid data (e.g. a required field is missing, an email field is invalid, ...). The response body should contain more details about the origins of the error.
The specified resource doesn’t exist or is not accessible anymore. You should make sure the specified URI is valid.
When Emailicious’ servers cannot treat your request adequately a response with
5XX status code is returned. Such instances should be rare and
intermittent and you should contact our support team if the problem
Emailicious’ servers encountered an undisclosed internal error processing your request and our engineers are working toward fixing the underlying issue. The response should contain an X-Sentry-ID header containing a UUID identifying your request that might be requested by Emailicious’ support team.
