Integration
Connect Calendly and OnceHub
When New scheduled event (polling) fires in Calendly, your agent runs Create Contact in OnceHub, or Booking Completed in OnceHub to Update event type availability schedule in Calendly. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.

Ask the assistant
Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

- 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 OnceHub, 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 OnceHub when something happens in Calendly?
Any of OnceHub's 17 actions, including Create Contact, Create One-Time Booking Link, Update Contact and Find Contact. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from OnceHub to Calendly?
Yes. When something happens in OnceHub, your agent can act in Calendly too. This page covers both directions: OnceHub's triggers and Calendly's actions are listed here as well.
Do I have to build a connector for Calendly or OnceHub?
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 OnceHub 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.
