How to install the Axur Cardstream integration through Azion Marketplace

Axur Cardstream is an integration that helps you protect your e-commerce from fraud even on the first purchase and, consequently, avoid the chargeback.

It’s a global list of cards leaked on the Internet, as well as the deep and dark web. With the API active, every time your client makes a purchase, you can check if the card has been exposed, request additional verification, or even cancel the transaction.

Requirements

To start using this integration, you need to:

Create an Axur account.
Get an Axur API Token.

Getting the integration

To install this integration:

Access Azion Console > Marketplace.
On the Marketplace homepage, select the Cardstream card.
On the integration page, click the Install button.

You’ll see a message indicating that your integration was successfully installed.

Click the Save button.

On the Console, you must now configure your domain so it is protected by your Edge Firewall.

On the Products menu, select Domains.
Click on the domain you want to protect with your Cardstream function.
