# ChipCard MSU

Accept card payments through the provider’s hosted checkout.

- Where: App Store → ChipCard MSU
- Status: Beta

Accept card payments through the provider’s hosted checkout.

## Before you start

ChipCard merchant credentials and the MSU addresses assigned to your account.

## Set up

Open the App Store, install **ChipCard MSU**, and open its settings. Save the merchant settings and validate them. Validation checks that the settings are complete; only a test payment proves the account works. Complete successful, declined and canceled test payments, then confirm the order outcome in Poltura and the provider account before using live credentials.

## Settings

Use the account identifiers and credentials issued for this connection. Save secret values only in the app’s credential fields. Keep test and production account details together.

Copy the **Notification URL** from **System endpoints** on the app page and enter it in the ChipCard merchant panel, under **Settings > Profile**, for financial transaction notifications. Without it, a payment is confirmed only when the shopper returns to the store.

Changing either MSU address, including the move from the test to the live addresses, erases the saved credentials and takes the app back to setup. Enter them again for the new address.

## Scope and limits

Start with the test account. Confirm the live addresses with ChipCard before switching.

## Troubleshooting

Check that the app is enabled, required settings are saved and the external account has the necessary access. If an operation has an uncertain outcome, check the external account before repeating it.
