Interactive Call-to-Action URL Button Messages

Your customers may be hesitant to tap raw URLs containing lengthy or obscure strings in text messages. In these situations, you may wish to send an interactive call-to-action (CTA) URL button message.

CTA URL button messages allow you to map any URL to a button so you don't have to include the raw URL in the message body.
