Use this endpoint to merge two or more contacts. The secondary contacts (mergeIds) will be merged onto the primary contact (primary_contact_id). Merge data includes conversation, chats, notes, views, etc. The primary contact ID in the endpoint URL (primary_contact_id) is required. Place the secondary_contact_ids in the request body.
Contact Ids can be found by going to the Acquire platform and hovering over a contact's name in Contact List or by using the endpoint GET All Contacts.
If a secondary merge's contact details are different from the primary contact details, both contact details will be preserved on the primary contact profile. For example, if a secondary merge contact has an email that differs from their primary email, both emails will be preserved on the primary contact profile after the merge.
