Questions
CalendarLink and Intervals, answered
What can start an automation from CalendarLink?
Any of CalendarLink's 1 trigger in the catalog, including New Upcoming Event. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Intervals when something happens in CalendarLink?
Any of Intervals's 38 actions, including Update client, Update expense, Update invoice and Update milestone. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Intervals to CalendarLink?
Yes. When something happens in Intervals, your agent can act in CalendarLink too. This page covers both directions: Intervals's triggers and CalendarLink's actions are listed here as well.
Do I have to build a connector for CalendarLink or Intervals?
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 CalendarLink and Intervals 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.
