Questions
freee and Kustomer, answered
What can start an automation from freee?
Any of freee's 2 triggers in the catalog, including New manual journal and Unsettled Deal. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Kustomer when something happens in freee?
Any of Kustomer's 21 actions, including Create Company, Create Conversation, Create Customer and Create Notes. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Kustomer to freee?
Yes. When something happens in Kustomer, your agent can act in freee too. This page covers both directions: Kustomer's triggers and freee's actions are listed here as well.
Do I have to build a connector for freee or Kustomer?
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 freee and Kustomer 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.
