Connect PostStack and Stannp
When Contact Updated (instant) fires in PostStack, your agent runs Create Recipient Event in Stannp, or New Recipient in Stannp to Add a contact in PostStack. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.

Questions
PostStack and Stannp, answered
What can start an automation from PostStack?
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 Stannp when something happens in PostStack?
Any of Stannp's 22 actions, including Create Letter, Create Postcard, Create Postcard via Recipient ID and Create Recipient Event. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Stannp to PostStack?
Yes. When something happens in Stannp, your agent can act in PostStack too. This page covers both directions: Stannp's triggers and PostStack's actions are listed here as well.
Do I have to build a connector for PostStack or Stannp?
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 Stannp 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.
