Hi @gacek, those
fromNumber fields are internal fields only that can only be pulled from the API. They do not have any implication who's names appear when logging a call. When submitting a call engagement via the API, the part that controls who logs the call (e.g. where it it says in your screenshot "You logged a call") is the
ownerId property within the "engagement" object. If you wanted to change who logs the call, you should insert a different ownerId in the property below by finding their internal ID here: https://app.hubspot.com/property-settings/3430672/contact/hubspot_owner_id
"ownerId": 1, <===== this property is the one that controls who logs the call
The call engagement will always appear on the associated contact specified in the associations sections:
"contactIds": , <==== contact vid goes here, this is the contact who's timeline the call will always log onto.
"companyIds": [ ],
"dealIds": [ ],
"ownerIds": [ ]
Let me know if I can clarify anything.
