Any of Hex's 4 triggers in the catalog, including New Project Run, List Groups, List Projects and List Users. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Cnpja when something happens in Hex? Any of Cnpja's 12 actions, including Update list, Add list, Find offices by criteria and Get company. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Cnpja to Hex? Cnpja has no triggers in the catalog today, so automations start in Hex. If you need the other direction, ask: your agent reads Cnpja's API documentation and adds it. ### ### Do I have to build a connector for Hex or Cnpja? 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 Hex and Cnpja without building an automation? Yes. With your AI client connected to APIANT, ask it to do something in Cnpja 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.
