Any of CalendarLink's 8 actions, including Create New Event, Update Event Collection, Find Event and List Contacts. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from CalendarLink to Apollo? Yes. When something happens in CalendarLink, your agent can act in Apollo too. This page covers both directions: CalendarLink's triggers and Apollo's actions are listed here as well. ### ### Do I have to build a connector for Apollo or CalendarLink? 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 Apollo and CalendarLink 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.
