Using Flow Builder, you can easily generate a Webhook endpoint that you can call to trigger an outbound SMS. Go to Flow Builder in the Dashboard, and create a new flow or use the template ‘Webhook to SMS’.

1. Click on the ‘Webhook’ Step, and set up the attributes. Click on save when ready.
2. Click on the ‘Send SMS’ Step, and fill up the originator, recipient, and the message you’ll like to display as a response. You can set up the flow complex as you want by adding Steps underneath. Remember to click on save when you add new Steps or set up Attributes.
3. When you are done building your flow, click on either ‘Save draft’ or ‘Publish’ on the right top of the screen.
4. Then a pop-up will appear with the URL that will trigger the flow and a URL request example.
