Capabilities

Tools 23

vision6_add_contacts

WRITE: add up to 200 contacts to a list in one request (faster than one by one). Each needs an email and/or mobile. Vision6 returns no contact data (HTTP 204), so use vision6_list_contacts to read them back. May trigger automations. POST /lists/{list_id}/contacts.

Discovered
vision6_create_contact

WRITE: add one contact to a list (needs an email and/or mobile that matches a field of the list). May trigger the list's 'contact created' automations and notification emails. Returns the new contact. POST /lists/{list_id}/contacts.

WRITE: create a new, empty contact list inside a list folder (see vision6_list_folders with type list). Returns the new list. POST /lists.

Discovered
vision6_create_message

DELETE /lists/{list_id}/contacts?id={contact_id}.
