Paytrail is a Finnish payment service provider that allows you to use several payment methods in your store, such as direct bank transfer, card, and invoice.
Installing the app
Adding the payment method
After you have installed the app, you can add the payment method to your online store by following these steps:
Go to Settings > Payment methods.
Click Add payment method.
Click the Choose button next to Paytrail.
Fill in the API credential into the fields on the page.
Important: After you have added the payment method, it's good to test it in your online store. Add some products to the shopping cart and place the order using Paytrail.
If it's not working correctly, you might want to check the credentials first. That's the most common problem with payments. If you're unsure about the credentials, Paytrail can help you to find them.
