Any of Stax's 1 trigger in the catalog, including List Payment. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Iucto when something happens in Stax? Any of Iucto's 25 actions, including Add received invoice, Add received payment, Send issued invoice by email and Update customer. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Iucto to Stax? Iucto has no triggers in the catalog today, so automations start in Stax. If you need the other direction, ask: your agent reads Iucto's API documentation and adds it. ### ### Do I have to build a connector for Stax or Iucto? 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 Stax and Iucto 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.
