Questions
PassEngine and Modern Treasury, answered
What can start an automation from PassEngine?
Any of PassEngine's 4 triggers in the catalog, including New Client, New Pass, Pass Status Changed and Pass Scanned. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Modern Treasury when something happens in PassEngine?
Any of Modern Treasury's 14 actions, including Update counterparty, Update payment order, Add counterparty and Add expected payment. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Modern Treasury to PassEngine?
Modern Treasury has no triggers in the catalog today, so automations start in PassEngine. If you need the other direction, ask: your agent reads Modern Treasury's API documentation and adds it.
Do I have to build a connector for PassEngine or Modern Treasury?
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 PassEngine and Modern Treasury 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.
