Connect PostStack to 3Dsellers
When Contact Updated (instant) fires in PostStack, your agent runs Generate Order Invoice in 3Dsellers. 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.

Give your AI client this address.
https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

Questions
PostStack and 3Dsellers, 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 3Dsellers when something happens in PostStack?
Any of 3Dsellers's 14 actions, including Create Product, Create Product Category, Update Product and Generate Order Invoice. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from 3Dsellers to PostStack?
3Dsellers has no triggers in the catalog today, so automations start in PostStack. If you need the other direction, ask: your agent reads 3Dsellers's API documentation and adds it.
Do I have to build a connector for PostStack or 3Dsellers?
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 3Dsellers 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.
