If the API offers "extended" or "full" response, in order to receive it please make sure that you add the following parameter to the API call:
- /msgtype:{value}/ replace {value} with extended (or full).
e.g. https://services.marinetraffic.com/api/exportvessels/gjwp9358ghq9hgq0gh8348qg8h3q84gh/v:8/msgtype:extended/timespan:15 . - if the /msgtype:{value}/ is omitted then the simple response is returned by default.
You may check which are the available message types (msgtype) for each API by visiting the respective API documentation page.
