Meetings set via API are not searchable in HS UI - Meetings tab

Hi @Jay-G,

You’re already mapping the default meeting activity fields - name, start time, etc, the piece that’s missing for UI discoverability might be the default Meeting source property (not the engagement-source fields).

Do not try to set hs_meeting_source in the create payload, as Meeting source is a read-only HubSpot property and cannot be set through the Meetings API.

If this helps, feel free to mark it as the solution :check_mark: and give it an upvote :+1: !
