MIT Authorization

POST 
/public/api/v1/mit

A MIT (Merchant-Initiated Transaction) is a payment initiated by the merchant, typically based on a previously established agreement, such as a subscription.

Use a MIT authorization when the customer has agreed to let the merchant charge them automatically. For example, monthly subscription payments must be handled using MIT. MIT is not suitable when the customer starts the payment themselves, like clicking a “Pay Now” button.

For more information about the differences between CIT (Customer-Initiated Transaction) and MIT, see our Core Concepts page.

All MIT transactions are processed asynchronously and cannot run in real time. Most are completed within a few seconds, but ePay does not guarantee processing times. Some payment methods, such as Vipps MobilePay, may take several days to complete, depending on the method’s processing rules.

If you want to offer your customers the ability to store their cards for faster checkout in the future, you must use CIT transactions. In such cases, you are required to provide a customerId when creating the payment. This ID links the stored card to the customer and enables quick-checkout functionality in future sessions.
