Integration
Connect OnceHub and Stax
When Booking Completed fires in OnceHub, your agent runs Create Customer in Stax, or List Payment in Stax to Create Contact in OnceHub. 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 Stax, 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 Stax when something happens in OnceHub?
Any of Stax's 17 actions, including Create Customer, Create Item, Create Scheduled Invoice and Update customer. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Stax to OnceHub?
Yes. When something happens in Stax, your agent can act in OnceHub too. This page covers both directions: Stax's triggers and OnceHub's actions are listed here as well.
Do I have to build a connector for OnceHub or Stax?
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 Stax 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.
