Send an envelope for signature
POST
/api/v1/envelopes/{id}/send
const url = 'https://sign-api.binarybridges.co/api/v1/envelopes/2489E9AD-2EE2-8E00-8EC9-32D5F69181C0/send';const options = {method: 'POST', headers: {Authorization: 'Bearer <token>'}};
try { const response = await fetch(url, options); const data = await response.json(); console.log(data);} catch (error) { console.error(error);}curl --request POST \ --url https://sign-api.binarybridges.co/api/v1/envelopes/2489E9AD-2EE2-8E00-8EC9-32D5F69181C0/send \ --header 'Authorization: Bearer <token>'Transitions the envelope to SENT, emails each signer their link, and returns the signing tokens. This is the point of no return: documents and signers are frozen, and the envelope.sent webhook fires.

Produced by the security filter chain, so there is no response body.
Authenticated, but the token lacks the role this operation requires. No response body.
No such resource, or it belongs to another organisation. Deliberately not a 403: a 403 across a tenant boundary confirms the id exists.
