How to send a Slack notification when a call is missed?

While Aircall has a direct integration with Slack, setting up notifications specifically for missed calls in Slack requires separate configuration. Zapier, which Aircall also integrates with, can be used to automate this process by following the steps below: 

1. Create a Webhook in Aircall:
   
   • Go to the Integrations tab in the Aircall Admin Dashboard
   • Find and click on the Webhook integration, then click Install integration
   • Enter a name in the Customer webhook name
   • In the events section, make sure that only the call.ended event is enabled
   • The URL will be entered after the next step
2. Set Up Zapier:
   
   • Create a new Zap in Zapier
   • For the Trigger select Webhooks by Zapier as the app, then Catch Hook as the Trigger Event
   • Click continue until you are to the Test tab, then copy the URL in the Your webhook URL field and paste it into the URL field for the Webhook integration started in step 1
3. Filter for Missed Calls:
   
   • Add a step to your Zap after Webhooks by Zapier and select Filter to set up a step that will filter out anything except missed calls
   • Configure the filter to only allow calls where the Direction is Inbound and the Missed call reason exists. This will filter our any calls that are not missed calls
4. Send Slack Notification:
   
   • After the Filter step, add another step where Slack is selected as the application
   • Select the Action event you want to execute, such as sending a Direct Message or a Channel Message
   • Customize the Slack notification with further details as needed
5. Test and Review:
   
   • Use the Test & Review option in Zapier to ensure the setup works correctly and notifications are sent as expected
