Integration
Connect Flatfile and Square
When New Agent fires in Flatfile, your agent runs Add order in Square, or New order in Square to Create Document in Flatfile. 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.
What do you want Flatfile and Square to do together?

Connect your AI client
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
Flatfile and Square, answered
What can start an automation from Flatfile?
Any of Flatfile's 8 triggers in the catalog, including New Agent, New App, New Document and New Event. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Square when something happens in Flatfile?
Any of Square's 19 actions, including Create customer, Update customer, Update order and Add catalog object. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Square to Flatfile?
Yes. When something happens in Square, your agent can act in Flatfile too. This page covers both directions: Square's triggers and Flatfile's actions are listed here as well.
Do I have to build a connector for Flatfile or Square?
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 Flatfile and Square 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.
