How to get a Cal.com API key

Updated over a week ago

To connect Cal.com as an MCP server in DialLink, you need an API key. This key allows DialLink to securely interact with your Cal.com environment: checking availability, creating events, and more.

Steps to create your Cal.com API key

  1. In your Cal.com account, go to Settings > API Keys.

  2. Click + New API key to create a new key.

  3. Provide a clear name and optional description for the key (e.g., "DialLink Integration").

  4. Click Save. Cal.com will generate your API key.

  5. Copy the API key when shown. This is the only time it will be visible.

  6. Store it in a secure location.

Security note

Treat your API key like a password. Don’t share it publicly, and keep it protected. If you suspect it has been exposed, revoke or rotate it immediately in Cal.com.
