Sending WhatsApp Appointment Reminders from ServiceM8
Last updated: April 5, 2026
If you use ServiceM8 to run your jobs, you can connect it to Broadcaster and send automatic WhatsApp reminders to clients before each appointment. Once connected, Broadcaster reads your ServiceM8 schedule and handles the reminders, nothing to send manually.
What your clients receive
Your client receives a WhatsApp message from your business number ahead of their job. The message includes their name, the appointment date and time, and any details from your reminder template. You choose when reminders go out, a few days before, the day before, the morning of, or a combination.
How to connect ServiceM8 to Broadcaster
ServiceM8 provides a calendar feed for each staff member through the External Calendars add-on. This is the feed Broadcaster uses to read your upcoming jobs.
Step 1: Enable the External Calendars add-on in ServiceM8
- Log into your ServiceM8 account on a desktop browser
- Go to Settings and then Add-ons
- Find External Calendars and enable it
Note: the External Calendars add-on costs 5 job credits per month in ServiceM8.
Step 2: Get your ServiceM8 iCal feed URL
- In ServiceM8, go to Settings and then Staff
- Click on the staff member whose calendar you want to connect
- Copy the Calendar URL from their profile
If you have a team, you need the calendar URL for a staff member who is assigned to all jobs — or connect multiple feeds if your work is split between staff members. Each staff member has their own unique URL.
Step 3: Add the feed to Broadcaster
- Log into your Broadcaster account
- Go to Settings and then Calendar connections
- Paste your ServiceM8 calendar URL
- Save the connection
ServiceM8 calendar feeds typically refresh every 15 minutes, which is faster than most other sources.
