Unenroll Contacts

Remove contacts from outreach entirely.

Every non-finished sequence of each contact is marked failed and manually stopped — including leads still waiting for approval — and the contact is excluded from all outreach for three months. Scope it to one template with sequence_template_id.

This is not POST /v1/sequences/{sequence_id}/stop: that closes one enrollment with an outcome (won or lost) and leaves the contact reachable.

Requires the sequences:write scope on the API key.
