Delete Contact List
Permanently remove a contact list from your account. The list is detached from any draft projects that reference it and no longer appears in list or read endpoints. Deletion is blocked with a 409 while a scheduled, sending, or active project depends on the list; unschedule the project or wait for the send to finish, then retry.
Authorizations
Authenticate every request by passing your API key in the X-API-Key header. Keys are scoped to your organization hierarchy.
Headers
Optional idempotency key: a unique string of 16-200 printable ASCII characters (a UUID is recommended). Retrying the write with the same key within 24 hours returns the stored response of the first call with an X-Idempotent-Replayed: true response header instead of executing it again. Reusing a key with a different request body returns 422 (IDEMPOTENCY_MISMATCH); a duplicate sent while the first call is still running returns 409 with a Retry-After header. Keys are scoped per endpoint and organization.
