## Scheduling API on all Calendly plans

The Scheduling API is now available on all Calendly plans, including the Free plan.

### Updated endpoint:

* **POST /invitees** – No longer requires a paid Calendly plan. Free plan usage is subject to endpoint-specific rate limits. See [Rate Limits](/api-docs/overview/rate-limits) for details. The `scheduled_events:write` scope is still required.

## Webhooks on all Calendly plans

Webhooks are now available on all Calendly plans, including Free.

* Some events need a plan that includes the feature: `routing_form_submission.created`, `meeting_recap.*`, and `contact.*`. See [Create Webhook Subscription](/api-docs/calendly-api/webhooks/create-webhook-subscription).
* The webhook endpoints use the standard API [rate limits](/api-docs/overview/rate-limits).
* The `403 Permission Denied` message for a plan that is not allowed is now `Please upgrade to a paid Calendly account.`.
