# Send the envelope under review

`POST /api/review/send`

The human approval action (spec §5.3): same contract as `POST /v1/envelopes/{id}/send`, scoped to the token's envelope — validates the stored document, requires ≥1 participant, transitions to `in_progress`, and emits the `atlas/envelope.sent` notification event. Requires a send-capable token (read-only links cannot dispatch).
