Response Formats

Given the ubiquitous support for JSON both on the client and the server, it is our sole data format for transmission over the wire.

Make sure the Content-Type header is set appropriately e.g. “application/json” for JSON.

We also use our internal lookup values for both input and output messages where they relate to controlled fields. This allows us to change the text of these values yet ensure that the integer constants always remain unchanged.
