What can I send from? All the organization's phone lines (each with its user and canSendSms) and your mailboxes; your lines have user.id = currentUser.id. "My number" to text from or give a teammate is one of these, not getMyProfile.phoneNumber. canSendSms is line setup only: while organization.textingReadiness.canText is false nothing texts, so never say a line can text; say what its reason value says to do. myDisconnectedMailboxes lost connection (disconnectedAt): say disconnected, reconnect; never no mailbox.

Errors

400unknown_variable

A variable the operation does not declare. A typo is refused rather than silently dropped.

401unauthorized

No bearer header, or the key is invalid or revoked.

403insufficient_scope

The key lacks the scope the operation requires.

403forbidden

A referenced record does not exist, was deleted, or is outside your organization. The gateway cannot tell those apart.

Behaviour

A read. It rejects an Idempotency-Key header with 400 bad_request.
