Handle Adyen Payments, Sessions, and Refunds Through Your Muse

If your business takes payments through Adyen, your muse can work the payment steps in plain words: list the methods a shopper can use, start a payment or a checkout session, and capture, refund, or cancel a payment when you approve it.

What it does

The connector adds 10 tools for one Adyen merchant account. It can list the payment methods available for a given currency, country, and amount. It can create a payment, and finish a payment after a shopper completes a step such as a bank challenge or a redirect. It can create a payment session for the current Adyen checkout, and read the result after the shopper has paid. For payments already taken, it can capture an authorized payment, refund a captured payment, cancel an authorization that has not been captured yet, and reverse an authorization in one step. It can also fetch origin keys, which older web checkouts used. Test and live stay separate, so a test run never touches real money.

How to use it

1. Start an AnythingMCP account and add the Adyen connector.
2. Sign in to the Adyen test or live area, open Developers, then API credentials, and create an API user. Generate its API key.
3. Enter the API key, your merchant account name, and whether this is test or live where the connector asks. For live, you also need the live address prefix Adyen issued to your account.
4. In Muse, open Settings, then Connectors, and add a custom connector with the address AnythingMCP gives you. Sign in and approve.
5. Start in test. Ask for the payment methods for a small amount in your main currency, then run one test payment and check it in Adyen before any live use.

What you need

• A Muse account that can add custom connectors
• An AnythingMCP account with the Adyen connector added
• An Adyen merchant account with an API user and API key

What to watch for

• These tools move money. Captures, refunds, and cancellations are real once they run, so approve each one and check the amount and the payment it belongs to first.
• Keep test and live keys in separate connector setups. Mixing them is the common way a test turns into a live charge.
• The origin key tool is there for older checkouts. Adyen replaced it in 2023, so most new setups will never need it.
• This is a custom connector, and Meta does not review custom connectors. You can disconnect it in Settings at any time. The muse prepares, you decide.
