Connect OnceHub to Mercury
When Booking Completed fires in OnceHub, your agent runs Add customer in Mercury. 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.

Questions
OnceHub and Mercury, answered
What can start an automation from OnceHub?
Any of OnceHub's 15 triggers in the catalog, including Booking Completed, Contact Updated, Booking Lifecycle Event and Booking No-Show. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Mercury when something happens in OnceHub?
Any of Mercury's 17 actions, including Send money, Update recipient, Update transaction and Add customer. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Mercury to OnceHub?
Mercury has no triggers in the catalog today, so automations start in OnceHub. If you need the other direction, ask: your agent reads Mercury's API documentation and adds it.
Do I have to build a connector for OnceHub or Mercury?
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 OnceHub and Mercury 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.
