Set the Cal.com trigger as “New booking”

A playbook always starts with a trigger, which is responsible for detecting changes in your connected applications and responding accordingly.

Add the Cal.com trigger to initiate your playbook's actions every time a new booking is made. Click "Add trigger" in your playbook and choose "New booking" from the dropdown menu under Cal.com.

If you still need to connect your Cal.com account to Relay.app yet, a prompt will guide you through the process.

Add the Slack Add users to channel step

Integrate the Slack automation into your playbook to ensure the prompt addition of users to a channel in Slack every time a new booking is made on Cal.com.

Click the "Add step" button, locate the “Add users to channel” automation for Slack, and input the mandatory and relevant details.

If your Slack account still needs to be connected to Relay.app, you will be prompted to complete that connection. Make sure to allow the necessary permissions for Relay.app to sync with your Slack account.

Activate your playbook

Activating your playbook is the last step in the process. Once you turn it on, it will automatically add users to a channel in Slack every time a new booking is made on Cal.com without requiring manual intervention.

To activate your playbook, click the toggle button at the header. Before activating, we recommend performing a test run of your playbook to ensure all the steps work seamlessly together.
