Generating an API key
Cal.com API keys are created from your account settings and authorize every request StackOne makes.

Open API key settings
In the settings sidebar, expand Developer and select API keys.
- Or go straight to the Cal.com API key settings.

Create a new API key
On the API keys page, click New in the upper right corner.

Name the key and set its expiration
In the Create an API key dialog, keep API key selected rather than OAuth Client.
- Enter a name under Name this key, for example
StackOne Integration. - Choose an Expiration date, or turn on Never expires so the key does not expire.

The API key created successfully dialog shows the key.
- Click the copy icon beside the key, then click Done.
- Cal.com API keys start with
cal_live_. - The key is shown only once — Cal.com warns that you will not be able to view it again once you close this modal.
