Adjust Authorisation allows you to modify the previously authorised transaction amount, either by increasing or decreasing it, before it is captured.

This is useful in industries where the final charge amount may not be known at the time of initial authorisation—such as hospitality, fuel, or car rental services.

Adjustments help reduce declines at the time of capture and improve customer experience by avoiding multiple holds on funds.

Use this flow when:

• The final charge differs from the initially authorised amount.
• Additional services or fees are added after the initial authorisation.
• You need to reduce the held amount due to cancellations or refunds.

Note: You need to specify the entire new Auth amount and not the difference.

Steps to Adjust Auth

1. Request an adjustment to the authorization by referencing the original authorization ID and providing the new amount to be held, in the Adjust Auth API.

   Parameter	Description
   amount	The new auth amount to authorize.

2. Track Status of Incremental Authorization: Use the Retrieve Authorization API to monitor the status of the incremental request.

3. Webhook Notifications: You’ll receive updates about the status of the authorization via the Transaction webhook. It will indicate whether the incremental auth was approved or declined by the issuer.
