Preauth
eWAY’s Pre-authorisation solution allows merchants to reserve funds on a customer’s credit card without charging it. They can then confirm the transaction at their convenience via MYeWAY or eWAY’s API. This service is perfect for merchants whose prices are dependent on variable costs.
PreAuth is supported by all of eWAY’s payment APIs simply by setting the “Method” to “Authorise”.
