What is the difference between an Auth transaction and a Validate transaction?
Validate just makes sure it is a valid card and authorizes a dollar charge, so that you know it isn’t an expired card or stolen etc. It is used for token billing purposes as a 1st transaction to store a billing id at the same time. Alternatively you could charge the card with a purchase. Note that the Validate transaction type is not enabled by default on live accounts. Please make a request to DPS Support if you would like to utilise this transaction type.
