- Undo invitee no-show

- Update event type availability schedule
Replaces a single host's availability schedule on a Calendly event type with explicit date rules (full overwrite). Built for CalendarConnect: push real Mindbody bookable slots into Calendly so only MBO-bookable times are offered. CRITICAL: the host is targeted by the NESTED availability_rule.user — a top-level user alone is silently ignored and Calendly replaces the OAuth token owner's schedule instead. Always verify stored_user equals the requested host before trusting the result. For round-robin events, call once per host.

Questions
Calendly and Quaderno, answered
What can start an automation from Calendly?
Any of Calendly's 2 triggers in the catalog, including New scheduled event (polling) and Canceled scheduled event (polling). Describe the moment in plain language and your agent picks the right one.
What can your agent do in Quaderno when something happens in Calendly?
Any of Quaderno's 24 actions, including Create Contact, Create Estimate, Create Expense and Create Invoice. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Quaderno to Calendly?
Yes. When something happens in Quaderno, your agent can act in Calendly too. This page covers both directions: Quaderno's triggers and Calendly's actions are listed here as well.
Do I have to build a connector for Calendly or Quaderno?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Calendly and Quaderno without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
