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 Google Tag Manager when something happens in OnceHub? Any of Google Tag Manager's 10 actions, including Create Tag, Create Version, Create Workspace and Update Tag. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Google Tag Manager to OnceHub? Google Tag Manager has no triggers in the catalog today, so automations start in OnceHub. If you need the other direction, ask: your agent reads Google Tag Manager's API documentation and adds it. ### ### Do I have to build a connector for OnceHub or Google Tag Manager? 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 Google Tag Manager 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.
