Aircall offers a direct Slack integration; however, sending notifications specifically for missed calls requires a separate setup. You can automate this with Zapier by creating a webhook in Aircall and a Zap that filters for missed calls, then posts to Slack.

Note: This workflow posts to Slack only when a call is missed. It uses the Aircall call.ended event and filters in Zapier.

Create a webhook in Aircall

Steps:

  1. Go to Aircall Dashboard > Integrations & API
  2. Find Webhook and click Install integration
  3. In the new window, enter a Customer webhook name
  4. In Events, enable only call.ended
  5. Leave the URL blank for now. You will paste it after creating the Zapier trigger

Set up the Zapier trigger

Steps:

  1. In Zapier, create a New Zap.
  2. For Trigger, choose Webhooks by Zapier.
  3. Select Catch Hook as the trigger event.
  4. Continue to the Test tab and copy Your webhook URL.
  5. Return to the Aircall Webhook integration and paste this URL into the URL field.
  6. Click Add webhook

Filter for missed calls

Steps:

  1. In your Zap, add a Filter step.
  2. Configure the filter to pass only when:
    • Direction equals Inbound, and
    • Missed call reason exists.

This ensures only missed inbound calls continue to Slack.

Send the Slack notification

Steps:

  1. Add an Action step and choose Slack.
  2. Select the action you prefer, such as Send Direct Message or Send Channel Message.
  3. Customize the message with call details from the webhook payload as needed.

Test and review

Steps:

  1. In Zapier, use Test & Review to validate the workflow.
  2. Confirm that a missed call triggers the Zap and the Slack message is received as expected.
  3. Turn the Zap On.
