Schedule smarter — book, qualify, and act without lifting a finger

SchedulingCRMSalesMarketingAutomationCommunicationProductivity

OnceHub is a scheduling and lead-capture platform that combines booking pages, chatbot qualification, and contact management into one pipeline-ready system. Connect it to Actionist and your agents can schedule meetings, recover no-shows, mark cancellations, route leads by segment, and react to every booking lifecycle event — all in real time, all without a rep lifting a finger. Whether you need to auto-book renewal calls when trials expire or fire a re-engagement sequence the instant a prospect no-shows, OnceHub gives your agents the scheduling backbone to close the loop autonomously.

Eliminates manual work. Agents eliminate manual no-show recovery, post-call CRM updates, re-engagement follow-ups, and cross-system booking synchronisation — the repetitive scheduling overhead that eats 14 hours a week across a typical revenue team.

No-show to re-booked in minutes

When a customer misses their scheduled check-in, your agent takes over the recovery sequence immediately — the booking is marked no-show in OnceHub, their future meeting schedule is checked for gaps, the CRM activity is updated, a personalised re-booking message lands in Slack for the CSM, and a fresh calendar hold is placed for the earliest available slot. The customer gets a re-engagement email before the rep has even noticed the missed call.

The fastest path — OnceHub's MCP server connects through a permissioned OAuth handshake so the agent can read bookings, manage contacts, and react to scheduling events without any token management on your end.

Open the Apps tab

Find OnceHub in the Apps library and click Connect. MCP is selected by default.

Authorise in OnceHub

You'll be redirected to OnceHub to approve the Actionist connection. Sign in with your OnceHub admin account and grant the requested scheduling and contacts permissions.

Test the connection

Actionist runs a read-only call to verify the handshake. You're ready.

FAQs

Questions about OnceHub + Actionist

How does Actionist connect to OnceHub?

The recommended method is MCP — you authorise the connection with your OnceHub admin account via OAuth, and the agent gains permissioned access to your bookings, contacts, and event types. No tokens to manage. Alternatively, you can use a personal API token generated from OnceHub Account Settings → Integrations → API.

Which OnceHub objects can the agent read and write?

The agent can read and write bookings (schedule, cancel, reschedule, mark no-show, get details, list), contacts (find, create, update, list, get future meetings), booking pages (create, update), event types (get details, list), and availability slots. It can also react to any of the 15 webhook triggers covering the full booking and contact lifecycle.

How do I avoid triggering infinite loops when the agent updates a booking?

Two safeguards prevent loops: first, use OnceHub's idempotency — the agent should check booking status before writing a change (e.g. confirm a booking isn't already marked no-show before marking it again). Second, in your Actionist workflow, add a condition node that checks whether the triggering event was itself agent-authored by comparing the booking's last-modified-by field. If the agent modified it, skip the write — loop broken.

Can the agent respond to events on all booking pages, or only specific ones?

OnceHub webhooks are configurable at the account level and can be filtered by booking page or event type. When you connect via MCP, Actionist registers listeners for the events you select. If you want the agent to react only to enterprise demo bookings, filter the webhook subscription to that specific booking page — the agent won't fire on SMB or support pages.

What happens if the agent tries to schedule a booking when no slots are available?

The agent first calls Get Available Time Slots to confirm availability before scheduling. If no slots are returned for the requested window, the agent can either widen the search range, send a Request Reschedule to the contact, or create a follow-up task for the rep to handle manually — your workflow design controls which fallback fires. The agent never blindly calls Schedule Booking without first verifying availability.

Does connecting OnceHub give the agent access to all team members' calendars?

The MCP connection is scoped to the OnceHub account you authorise — it can access booking pages, contacts, and bookings within that account but does not touch the underlying calendar apps (Google Calendar, Outlook) directly. Calendar changes surface in OnceHub as booking updates; the agent modifies scheduling through OnceHub's API, not by writing to calendar apps directly.

How does the agent handle cancelled-and-rescheduled bookings differently from plain cancellations?

OnceHub fires distinct webhook events: Booking Canceled for a plain cancellation, and Booking Cancelled and Rescheduled when the contact immediately picks a new slot. Your agent can route these differently — a plain cancellation triggers a re-engagement email, while a cancel-and-reschedule updates the CRM deal with the new meeting time and skips the recovery sequence entirely. One webhook, two different downstream paths.

Are there rate limits I should be aware of when running high-volume booking automations?

OnceHub's API enforces rate limits on a per-account basis; the exact threshold is documented in their developer portal. For high-volume workflows — such as batch-creating bookings after a webinar — the agent should use List Bookings to retrieve existing records before creating new ones, and space write operations using a queue rather than firing them all simultaneously. If your workflow processes more than 50 bookings per minute, contact OnceHub support to confirm your plan's API limit.
