What can you do with Cal.com on Tray.ai?
Cal.com is an open-source scheduling platform where people publish booking pages, manage availability, and route meetings across individuals and teams. Tray.ai connects to Cal.com through the HTTP Connector, so your workflows can call the Cal.com API alongside the rest of your stack.
- When Cal.com sends “Booking created”, log the meeting against the contact in your CRM.
- When Cal.com sends “Booking cancelled”, notify the account owner in your team chat.
- When Cal.com sends “Recording ready”, attach the recording link to the deal in your CRM.
- Create a booking for an onboarding call as soon as a new customer signs up in your billing system.
- Connects through
- HTTP Connector
- Authentication
- A bearer token or OAuth 2.0
- Base URL

Set it up
Connect Cal.com to Tray.ai
Each step uses Cal.com's own API details, from its documentation.
Step 1
Save Cal.com's API token
Save the token Cal.com issues as a Tray.ai authentication. The HTTP Client sends it as a bearer token on every call. The token stays out of the workflow and out of the logs.
Step 2
Point the HTTP Client at the API
Add an HTTP Client step and use https://api.cal.com/v2 as the base URL. Or paste a cURL example from Cal.com's API docs, and Tray.ai fills in the method, URL, and headers.
Step 3
Start with “List bookings”
It's one of 20 documented actions, under Bookings. The response comes back as data the next step can map into your other apps.
Step 4
Start workflows from Cal.com events
Give Cal.com the URL of a Tray.ai webhook trigger. “Booking created” can then start a workflow, and so can 8 other events.
