Any of AddEvent's 4 triggers in the catalog, including New Calendar, New Calendar Subscriber, New Event and New RSVP Attendee. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in OpenRegister when something happens in AddEvent? Any of OpenRegister's 14 actions, including Find Company by Name, Find Company by URL, Find Insolvency Proceedings and Find People by Name. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from OpenRegister to AddEvent? OpenRegister has no triggers in the catalog today, so automations start in AddEvent. If you need the other direction, ask: your agent reads OpenRegister's API documentation and adds it. ### ### Do I have to build a connector for AddEvent or OpenRegister? 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 AddEvent and OpenRegister 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.
