Expresspay
ExpressPay: Direct Payment Processing
Ideal for applications with a predefined payment flow or a single preferred payment method.
ExpressPay offers a streamlined approach to payment processing. This integration method is designed for scenarios where:
- You have already implemented a checkout process in your application.
- A specific payment method has been pre-selected or is preferred.
- You aim to minimize the number of steps in the payment flow.
With ExpressPay, you can initiate payment requests directly, bypassing the need for a separate checkout page. This results in a more efficient and focused payment experience for your customers.
If you need a modern, standard, intuitive checkout for your platform, Fenan offers a hosted checkout solution. The general flow is that the customer will be redirected to the Fenan checkout page, and after the payment is completed, the customer will be redirected back to your platform. You do this by creating a payment intent first, for which you will get a checkout URL for that specific transaction, and you need to redirect the user to that page. After the payment is done, the customer is redirected back, and a webhook is sent to your server.

How to Create Express payment
If you are coming from the checkout process, everything remains the same except for the baseUrl
, methods
parameter and the Response. You will need to change only one payment method in the methods
parameter. Every other parameter remains the same. Here methods is string only accepting one payment type.
To create a payment intent, all you need to do is send a POST HTTP call to the appropriate endpoint based on your environment. Include the apiKey
in the request headers and provide the required parameters in the body as described in the Parameters section.
