Merchant-Initiated Incremental Transaction with

TMS

An incremental authorization is used to increase the total amount authorized for a payment if the initial authorization does not cover the total cost of goods and services. An incremental transaction is an additional amount to the original authorization. The final authorized total includes amounts for both the initial and the incremental authorizations. Incremental transactions are limited to certain merchant categories, such as rental, lodging, transit, amusement parks, restaurants, and bars.

This section describes how to process a merchant-initiated incremental transaction using these

token types:

Customer

Customer tokens store one or more customer payment instrument tokens and shipping address tokens.

Including a customer token eliminates the need to include billing information, card information, and the previous transaction's ID.

"paymentInformation": {
  "customer": {
    "id": "07C9CA98022DA498E063A2598D0AA400"
  }
}
