This guide walks you through obtaining all required credentials for the Cal.com (cal) plugin.

​
Authentication Method

The Cal plugin uses API key authentication.
  • api_key (default) — Cal.com API key for server-to-server access

​
API Key

​
Step 1: Create an API Key in Cal.com

  1. Log in to Cal.com.
  2. Open Settings → Developer → API keys (wording may appear as Developer or API depending on your Cal.com version).
  3. Click to create a new API key.
  4. Give it a label (for example, Corsair) and confirm any scope or permission prompts.
  5. Copy the key when it is shown — you typically cannot view it again after creation.
Storing credentials: 
pnpm corsair setup --plugin=cal api_key=your-cal-api-key
Verify: 
pnpm corsair auth --plugin=cal --credentials

​
Webhooks (Optional)

If you use Cal.com webhooks, configure the signing or verification secret Cal provides for your webhook endpoint and store it as webhook_signature if your deployment verifies incoming requests with the value Corsair reads from the key store. 
pnpm corsair setup --plugin=cal webhook_signature=your-webhook-secret
