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.
Discovered vision6_create_list
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
WRITE: save a new email or SMS message in Vision6. This only stores the message; it is NOT sent (use the Vision6 app to send a campaign, or vision6_send_transactional for a one-off send). Email needs email_type, subject and matching body fields (plain: content_text; html: content_html; plain-html: both; raw_html: content_html or content_html_raw). SMS needs content_sms. The drag-and-drop builder is not supported. POST /messages.
Discovered vision6_delete_contact
WRITE, IRREVERSIBLE: permanently delete one contact from a list (for example for a privacy erasure request). To stop emailing someone but keep the record, use vision6_update_contact with email_subscribed=false instead. Pass confirm=true only after the user agreed to the deletion. DELETE /lists/{list_id}/contacts?id={contact_id}.

Up to 100 recipients per call, each identified by exactly one of contact_id, email or mobile, plus optional personalisation values (wildcards %%key%% in the body).
