SMS

The SMS channel handles two-way text messaging through Telnyx, routing conversations into your unified Inbox. SMS shares its Telnyx credentials with the Voice channel.

Connect SMS

Section titled “Connect SMS”

  1. In the left sidebar, open AI Agents, then select Connect channels and pick the SMS channel card on the right side of the map.

  2. Under Telnyx Account, enter your API Key, Public Key, and Connection ID. If Telnyx was already configured for Voice, the same credentials are detected and reused automatically.

  3. Save the credentials, then add the Connection ID so Kasbly points at the correct Telnyx setup.

  4. Copy the webhook URL shown under Webhook status into Telnyx to register delivery and inbound-message callbacks.

SMS channel status

Section titled “SMS channel status”

The top of the page summarizes your connected numbers, SMS-enabled numbers, default sender, and webhook status — so you can confirm at a glance that SMS is ready. A Telnyx setup steps panel on the same page walks you through the process until the channel shows as connected.
