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 REsimpli when something happens in PostStack? Any of REsimpli's 33 actions, including Create Buyer, Create Lead, Create Tag and Create Vendor. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from REsimpli to PostStack? Yes. When something happens in REsimpli, your agent can act in PostStack too. This page covers both directions: REsimpli's triggers and PostStack's actions are listed here as well. ### ### Do I have to build a connector for PostStack or REsimpli? 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 REsimpli 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.
