Flexible Incremental Authorization

Use this information to process an incremental authorization for a Flexible transaction. You can process multiple incremental authorizations for a single EV charging session. Use this type of authorization when the final transaction amount of the charging session is more than the amount of the initial authorization. When the final transaction amount is less than the total authorized amount, an automatic, host-generated partial reversal request is sent.

For more information about this payment service, see Flexible Transaction Scenario.

Endpoints

PATCH /pts/v2/payments/{id}

The {id} is the transaction ID returned in the original authorization response.

Example

This example shows a REST incremental authorization request for a Visa transaction in the Flexible scenario.
