Manage Payments - Increment

This guide focuses on incrementing an existing authorized transaction.

Increment is an action used to add a supplemental charge to the authorized amount for an existing transaction before it is batched. This is commonly done in a lodging scenario where upcharges for extra days might be necessary. The increment action does not change the status of a transaction. If successful, it increases the amount of the existing transaction.

The main things to know about increment:

• Availability in production depends on your configuration
• Only works on transactions that have not been captured (same day or in a delayed-capture status)

Before starting the steps in this guide, you must do the following:

• Get registered
• Create an app (generate keys)
• Create an access token

In this step, we increment an existing authorized transaction.
