Trying to add contacts to an outbound campaign contact list via S2S OAuth. The endpoint returns error 300 “Validation Failed” with contact_phones and contact_display_name listed as missing, even when present in the payload.
Captured the ZCC portal network traffic — the UI hits https://us01cci.zoom.us/v1/campaignContactItem with these fields: phones (array of {phoneNumber, phoneType, priority}), displayName, firstName, lastName
What are the correct field names for the public v2 endpoint? Or is there an alternative supported endpoint for batch contact injection via S2S OAuth?
