How does the integration between AddEvent and OnceHub work in WEXTL?

Frequently asked questions
Common questions about connecting AddEvent and OnceHub.
Connect your AddEvent and OnceHub accounts once, pick a trigger in one app and an action in the other, then map the fields so data flows automatically between them. [3]
Example: when AddEvent's "Watch Calendar" fires, WEXTL can "Book a Time Slot" in OnceHub. AddEvent has 6 triggers (including Watch Calendar, Watch Calendar Subscribers, and Watch Calendar Templates); OnceHub has 25 actions (including Book a Time Slot, Cancel a Booking, and Create a Contact). Add filters and transforms between steps when you need them. [1]
Yes — the integration works in both directions. Use each app's triggers to start a workflow and the other app's actions to update it. [2]
No. AddEvent-to-OnceHub automations are built visually on the canvas. You can optionally add custom JavaScript with Functions when you need advanced logic. [4]
Yes. Trigger-based automations start the moment AddEvent (or OnceHub) fires a new event — webhook-backed apps run within seconds, and polling-only apps re-check on a schedule you control. [7]
A first automation typically takes 5–10 minutes: connect each app's credential once, drop a trigger + action onto the canvas, map the fields, and turn the workflow on.
You can build your AddEvent + OnceHub automation on a 3-day trial with every feature unlocked. Cancel anytime. For your protection, a small deposit is charged to your card when your trial starts. It counts toward your first payment and is non-refundable. [8]
