In our previous blog, we have shared some tips on how to setup ad-hoc fields (better known as custom fields in other applications) as well as the type and configurations available. Here we would like to share the details in accessing the ad-hoc fields via web service.
In order to access these fields via web service, we may only need to obtain the name property and these operations can be performed: Query (not as query parameters), Create, Update. Do note that passing in empty field values will not remove previously added fields.
Sample update request schema of the ad-hoc fields:
1223 ... External ID a2323 ...
