# Connect Adyen and Square

When **New payment authorisation** fires in [Adyen](https://apiant.ai/connections/adyen), your agent runs **Add payment** in [Square](https://apiant.ai/connections/square), or **New order** in Square to **Add payment** in Adyen. Describe the whole flow and it is built, tested on every scenario and kept running.

Adyen **2** triggers Adyen **10** actions Square **3** triggers Square **19** actions

What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.

## What do you want Adyen and Square to do together?

Give your AI client this address.

`https://mcp.apiant.ai`

One 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.

### Set it up in your client

### Claude Code

Run this in the directory you want to work in.

`claude mcp add --transport http -s project apiant-ai https://mcp.apiant.ai`

Start Claude Code there, approve the server, and sign in in the browser page it opens.

[Claude Code guide (opens in a new tab)](https://apiant.ai/docs/mcp/claude-code)

###

### What can your agent do in Square when something happens in Adyen?

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 Adyen?

Yes. When something happens in Square, your agent can act in Adyen too. This page covers both directions: Square's triggers and Adyen's actions are listed here as well.

###

### Do I have to build a connector for Adyen 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 Adyen 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.
