How to Get Your Cal ID API Key

​

Create your API key

1

Open the developer dashboard

Log in to your Cal ID account, click Settings, then scroll the left sidebar to the Developer section and click API Keys.

2

Start a new key

Click Create an API Key. A configuration window appears.

3

Name the key

Enter a descriptive name in the Name this key field — for example, “My Personal Portfolio” or “Zapier Integration.” A clear name makes it easy to tell later which app uses which key.

4

Set an expiration

Decide how long the key stays active.

• Never expires
• Set an expiry date

Switch the Never expires toggle ON. The key stays active until you manually delete it.

Leave the toggle OFF, open the Expiration date dropdown, and choose 7 days, 30 days, 3 months, or 1 year.

Once this date passes, the key expires and the integration stops working until you create a new one.

5

Create and copy the key

Click Create. Your secret key is shown once — click the copy icon and paste it somewhere safe, like a password manager.

For your protection, Cal ID will never show this key again. If you close the window without copying it, delete the entry and create a new one.

​

Make your first request

GET https://api.cal.id/users/me

curl -X 'GET' \
  'https://api.cal.id/users/me' \
  -H 'accept: application/json' \
  -H 'Authorization: Bearer calid_XXXXXX'

​

Key security rules

• Never share your API key in emails, chat messages, or public code repositories like GitHub.
• Use separate keys for different integrations — safer than reusing one key everywhere.
• Revoke unused keys from the API Keys page with the Delete (trash) icon to cut off access instantly.
