Integration
Connect AddEvent and freee
When New Calendar fires in AddEvent, your agent runs Add deal in freee, or New manual journal in freee to Create Event in AddEvent. 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
AddEvent and freee, answered
What can start an automation from AddEvent?
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 freee when something happens in AddEvent?
Any of freee's 22 actions, including Create Item, Create Partner, Create Tag and Update deal. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from freee to AddEvent?
Yes. When something happens in freee, your agent can act in AddEvent too. This page covers both directions: freee's triggers and AddEvent's actions are listed here as well.
Do I have to build a connector for AddEvent or freee?
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 freee 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.
