summary: List messages held for human approval
description: 'A key configured to require approval drafts rather than sends: POST /v1/emails answered 202 with status pending_approval and an approval_id, and the draft waits here. There is nothing to retry. Returns every approval still pending and not expired (they expire 72 hours after the send by default), oldest first. Not paged: limit and cursor are ignored and next_cursor is always null. Every pending approval is returned; has_more is true when there are 500 or more, even though nothing is left out.'

summary: Approve or reject a held message
description: 'Decides one held send. Only an API key without guardrails that did not make the draft can decide: an OAuth access token, the key that made the draft, and any key with a guardrail (requires_approval, allowed_recipients or a daily_send_limit) are refused with 403 forbidden, so an agent cannot release its own mail, another held agent''s, or mail its own limits would not allow. A person in the dashboard can always decide. Rejecting marks the message canceled. Approving first re-checks suppressions and topic opt-outs for every recipient (dropping anyone who left; if no To address remains nothing is sent, the message is recorded rejected, and the response carries skipped and reason) and the plan allowance. Then, if the draft carried a scheduled_at still in the future, the message is put on that schedule (status scheduled, scheduled_at in the response): approving does not bring the send forward. Otherwise it is sent now and scheduled_at is null. The approval is recorded as approved only once the release works: on any failure the approval stays pending with the reason, and can be approved again once the cause is fixed (until it expires). Only one decision lands: 409 invalid_state means it was decided or expired, do not retry; 409 approval_in_progress means another decision is releasing it right now, check the list again in a moment. The key''s allowlist and daily cap are not re-checked.'
