• Adding Appointment Reminders is a simple API call from your scheduling or CRM software to Twilio. Notify your customers of upcoming appointments and let them make changes without ever speaking to a live agent.

  • STEP 1

    Start with an appointment

    Build appointment reminder logic into your scheduling app. Use this logic to trigger messages to your customers in advance of upcoming appointments.

  • STEP 2

    Create a REST API call to send an SMS

    Build a Twilio client that your software uses to send an SMS via the Twilio REST API. At the configured time an SMS reminder is sent out to the customer to remind them of their appointment.

  • STEP 3

    Set up voice fallback

    Use Twilio’s SMS status response API to gather delivery information. If your message is not delivered, Twilio can place a call and read the message using Text-to-Speech.

  • STEP 4

    Process the response

    The user responds with a confirm, change, or cancel SMS. For voice reminders the user can select options via touch-tone, for example “press 1 to confirm”. Use webhooks to update your appointment reminder system and transfer to a live person if needed.
