Connect Overloop.ai and PostStack
When List Created fires in Overloop.ai, your agent runs Add a contact in PostStack, or Contact Updated (instant) in PostStack to Add list in Overloop.ai. 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
Overloop.ai and PostStack, answered
What can start an automation from Overloop.ai?
Any of Overloop.ai's 2 triggers in the catalog, including List Created and New Exclusion List Item. Describe the moment in plain language and your agent picks the right one.
What can your agent do in PostStack when something happens in Overloop.ai?
Any of PostStack's 31 actions, including Send an email, Send broadcast, Send emails in batch and Update a contact. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from PostStack to Overloop.ai?
Yes. When something happens in PostStack, your agent can act in Overloop.ai too. This page covers both directions: PostStack's triggers and Overloop.ai's actions are listed here as well.
Do I have to build a connector for Overloop.ai or PostStack?
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 Overloop.ai and PostStack 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.
