Where is SourceName in the api?

Where is SourceName in the api?

We would like to make a note on the contacts how they signed up, and I am guessing the SourceName via the web interface is the appropriate field. However I cannot find anywhere in the api to fill it in.


This will be a free form field like it appears is available via the web interface for a contact.


Please direct me to where I can find it.  We are using the C# wrapper.

Re: Where is SourceName in the api?



The source name is automatically assigned for contacts based on your API Key, and this is done on the back-end of the API. As such it is not a field that can be freely set when creating or modifying contacts.


The best way to make a note on a contact is to use a custom field to store that data. In the V2 API custom fields are limited to a fixed set, and you can read a bit more about that here:


Please let me know if you have any questions!
