Hi HubSpot Community team,
We’re running business of softhone software, and is integrating with HubSpot. I noted that call properties are listed as fixed ones in your api documentation:
Can I custom more call related properities? If yes, can they be displayed in user’s Hubspot properties preview (Contacts--> calls--> call title--> Preview-->Actions--> View all properties)?
Hope for your soon reply.
Thank you very much!
