The integration without API is simple as we need the merchant to provide ETpay with the following information:

• Deposit data
• Site URL (optional, to redirect the client when the payment is completed). In case of not having a URL it will redirect to the ETpay page.
• Contacts that will have access to Backoffice and Freshdesk
• Duration of the payment session, by default it is set to one hour.
