Service businesses using Opencals often have a full day of appointments to manage, with customers expecting clear updates before and after each visit. A new confirmed appointment can trigger a Mobile Message text with the time and location. Appointment Cancelled and Appointment Rescheduled can start separate SMS workflows, so customers receive the latest information without waiting for someone to notice the change.

Mobile Message supports Send SMS, Send SMS to List, Create Contact, Update Contact, and list management actions. You can create a contact when an appointment is confirmed, send a cancellation notice, or text a customer after Appointment Completed. Customer Feedback Shared can also begin a message asking the customer to take the next appropriate step, using the information available in Opencals.

Opencals supplies triggers but no actions in the provided Zapier surface. The connection therefore sends Opencals events into Mobile Message rather than writing SMS activity back into Opencals. Build each workflow in Zapier, select the relevant trigger, and map the customer's number and appointment fields. Keep reminders and changes concise so the customer can act from the text alone.
