Exits

Exit	When It Triggers	Recommended Action
Success	The message was accepted and sent successfully.	Continue the flow, or end it if no further action is needed.
SMS error	The message could not be delivered due to a network issue or a carrier spam filter.	Retry, notify an internal team, or fall back to another channel.
Invalid Number	The destination number provided is not a valid phone number.	Log the failure and end the flow, or route to a manual follow-up process.
Error (not shown by default)	An unexpected error occurs during execution that isn't covered by the exits above.	Configured via the component's Error Handling / on_error setting rather than a visible transition.

Send SMS Notification exposes three visible exits, plus an internal error exit used for unexpected failures.

Error Handling

Use the Error Handling section in the component panel to define behavior for unexpected failures during execution, in addition to the SMS error and Invalid Number exits. For full documentation, refer to the Error Handling article in the Talkdesk Studio™ documentation.

How Send SMS Notification Works

When the component executes, it sends the configured message to the destination number using the selected outbound number or alpha sender ID, via the Automated Notifications SMS service. The flow proceeds through the corresponding exit based on the outcome of the send attempt.

Typical Flow Pattern

Trigger the flow via API, or from an inbound voice/message interaction.
If the destination number and message content are not already in context, use a Run Function component to derive them from the triggering payload.
Add Send SMS Notification and map the outbound sender, destination number, and SMS content fields.
Connect the Success exit to end the flow or continue automation.
Connect SMS error and Invalid Number to appropriate fallback handling (e.g. logging, retry, or escalation).
