Configuration

For Adyen to appear as an available payment gateway, you need to install it in the Saleor Dashboard. You must obtain the API key from Adyen and paste it into the Adyen App configuration form. Then, a wizard will guide you through the process of configuring the Adyen App, setting up the webhook to receive notifications from Adyen, generating the HMAC key, and adding allowed origins for the Client Key that's used on your Storefront.

You can install the Adyen app directly from your Saleor Dashboard. Go to the Apps section and click the Install button next to the Adyen app. Follow the instructions on the screen. After the installation is complete, select the Adyen app from the list of installed applications.
