List Calendly scheduled events and their invitees, and cancel events, via the Calendly API v2.

Calendly

List your Calendly scheduled events and the invitees booked on them, and cancel events — using the Calendly API v2.

Standard-library Python only (no external packages). The tool authenticates with a single Calendly Personal Access Token sent as Authorization: Bearer, so no live OAuth flow is required.

Operations

operation	Calendly endpoint	params
`me`	`GET /users/me`	—
`list_events`	`GET /scheduled_events?user=<uri>`	`user` (optional), `statusFilter`, `count`
`list_invitees`	`GET /scheduled_events/{uuid}/invitees`	`event` (required), `statusFilter`, `count`
`cancel_event`	`POST /scheduled_events/{uuid}/cancellation`	`event` (required), `reason` (optional)

Notes: - /scheduled_events must be scoped to a user (or organization). If you omit user, the tool calls GET /users/me first and lists your events. - event accepts either a bare event UUID or the full event URI returned by list_events (e.g. https://api.calendly.com/scheduled_events/<uuid>). - statusFilter is active or canceled for both list operations.

apiKey setup

Sign in to Calendly.
Go to Integrations & apps → API & Webhooks (https://calendly.com/integrations/api_webhooks).
Under Personal Access Tokens, generate a token.
Pass that token as the apiKey input. It is sent as Authorization: Bearer <token>.

Examples

List your upcoming (active) events, newest page of 10:

operation     = list_events
apiKey        = <your token>
statusFilter  = active
count         = 10

See who is booked on a specific event, then cancel it with a reason:

operation = list_invitees
apiKey    = <your token>
event     = https://api.calendly.com/scheduled_events/AAAAAAAAAAAAAAAA

operation = cancel_event
apiKey    = <your token>
event     = AAAAAAAAAAAAAAAA
reason    = Rescheduling to next week

Output

Both result (the raw Calendly JSON payload as a string) and status (the HTTP status code) are published, referenceable downstream as {{run.result}} and {{run.status}}.
