Connect Claude & ChatGPT to Nexi Checkout

Ask your AI what happened to a payment in Nexi Checkout (formerly Nets Easy): how much is reserved, charged, refunded or cancelled. It can create a checkout payment for an order, charge a reservation when the goods ship, refund a customer in full or in part, and cancel an uncharged reservation. It can also read subscriptions and charge them, with every money-moving action behind your approval if you want.

Try asking

“What is the status of payment 0260000065a1b2c3?”
The AI reads the payment and shows the reserved, charged, refunded and cancelled amounts, the payment method and the customer.
“Order 5512 has shipped. Charge the full reservation.”
It captures the reserved amount on the payment, so the money is taken from the customer, and returns the charge ID.
“Refund 249 DKK on payment 0260000065a1b2c3 for the returned item.”
It creates a partial refund in minor units with the returned order item. It can then read the refund to check its state.

What your AI can do

Payments and checkout

Create checkout payments, update the order before checkout completes, end an open checkout and set your own reference for accounting.

Charges, refunds and cancels

Charge reservations in full or in part, refund payments or single charges, cancel uncharged amounts and cancel pending refunds.

Subscriptions

Read scheduled and card-on-file subscriptions, find imported ones by external reference, and charge them.

“Create a payment link for 2 T-shirts at 199 DKK each.”
It creates a checkout payment with the items and total and returns the payment ID and the hosted page URL to send to the customer.
“The customer cancelled before we shipped. Release the reservation.”
It cancels the reserved, uncharged amount so the customer's funds are released. This cannot be undone.
“Charge this month's subscription for subscription ID 4f7c...”
It reads the subscription with interval and masked card, then charges it, which creates a new payment on the saved card.

Questions

What can the AI do in Nexi Checkout?

The AI can read payments, charges, refunds, subscriptions and your payment methods. It can create checkout payments, update an order before checkout completes, end a checkout, set your own reference, charge and refund payments, cancel reservations and pending refunds, and charge subscriptions, if you switch those tools on.

Does the AI see my Nexi Checkout secret key?

No. Your Nexi Checkout secret key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with lookups only. Charging, refunding and cancelling move real money or release a customer's reservation, and they can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Nexi Checkout account, and any fees Nexi charges are between you and Nexi.

Is Nexi Checkout the same as Nets Easy?

Yes. Nexi Checkout is the online card payment service from Nets/Nexi that used to be called Nets Easy. If you have a Nets Easy account, you connect it with the secret key from Company › Integration in the Nexi Checkout portal.
