Any of Harvest's 16 triggers in the catalog, including New Client, New Contact, New Expense and New Invoice. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Quadratic when something happens in Harvest? Any of Quadratic's 8 actions, including Update cells, Update code cell, Add file and Get cells. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Quadratic to Harvest? Quadratic has no triggers in the catalog today, so automations start in Harvest. If you need the other direction, ask: your agent reads Quadratic's API documentation and adds it. ### ### Do I have to build a connector for Harvest or Quadratic? 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 Harvest and Quadratic 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.
