SMS

Send: Send SMS. The sender is either an alphanumeric sender (up to 11 characters, approved by our team) or a phone number. Set trafficType to alerting for transactional messages (it defaults to marketing). Follow the delivery with the v2.sms.outbound.updated webhook.
Receive: SMS sent to your numbers trigger the v2.sms.inbound.received webhook, and the inbound-sms branch of the scenario attached to the number.
Search: Search SMS requires a direction and a creation date range (createdAfter, createdBefore).
