To create the app you will need to log-in to your account or to register a new one on paymaster24.com
Next you will need to go to the Site list.
Create a new app. To do that click on the "Add new" button.
Next fill the form. Specify your website's name and address (URL) and choose the appropriate site category.
Now you will need to specify the Callback URL. All callback URLs are available in the extension settings.
Next you will need to select the Signature type and to enter the Secret key. The Secret key will be required in the extension settings.
A word of advice! Save the Secret key. After saving it you will be able only to replace it. If the key is changed in the app, don't forget to change it in the extension as well.
Enable the extension
