# sendText

Send an SMS to a phone number (E.164, e.g. +13235550100; an unparseable number is rejected up front with INVALID_PHONE_NUMBER) as the key owner. NEEDS THE ORGANIZATION'S SEND CONSENT ATTESTATION: until an org admin attests once that every contact the organization messages through the API consented (setSendConsentAttestation; read it with getSendConsentAttestation), this is refused with 403 send_consent_not_attested, and while the org has paused everything it is refused with 403 outbound_paused. Runs the checks the app's composer runs: opt-out and Do-Not-Contact guard, A2P active-campaign gate, send throttles and daily caps, find-or-create contact from the number, and conversation + activity logging. A 200 response is NOT delivery: check status: FAILED or SKIPPED means the message never reached the contact (errorCode/errorMessage say why) even though the row is returned without a GraphQL error. Omit fromPhoneLineId to use your assigned line; sending from another user's assigned line requires the VIEW_ALL_PHONES capability (org-shared bulk lines are usable by any org member without it; another organization's line is never usable). Call listCommunicationChannels first and pick a line whose canSendSms is true.
