Any of PostStack's 7 triggers in the catalog, including Contact Updated (instant), New Contact (instant), New Inbound Email and New Sent Email (instant). Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Mx Technologies when something happens in PostStack? Any of Mx Technologies's 35 actions, including Update account, Update budget, Update category and Update goal. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Mx Technologies to PostStack? Mx Technologies has no triggers in the catalog today, so automations start in PostStack. If you need the other direction, ask: your agent reads Mx Technologies's API documentation and adds it. ### ### Do I have to build a connector for PostStack or Mx Technologies? 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 PostStack and Mx Technologies 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.
