Capture Adjustment

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

This is useful in industries where the final charge amount may change—such as hospitality, fuel, or car rental services.

Adjustments help reduce declines and improve customer experience by avoiding multiple holds on funds.

Use this when the final charge differs.

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

Steps to Adjust Capture

To Adjust a Capture:

1. Use the PUT /checkout/v3/payment/{id} endpoint that includes:

   Parameter	Description
   ternderType	Set to CARD for card transactions.
   paymentToken	Secure payment token for the authorization to be adjusted.
   amount	New amount (in US currency units). Can be higher or lower than the previously mentioned amount.
   merchantId	Merchant location ID.

2. The GET /checkout/v3/payment/{id} endpoint gives a response with new amount.

   • amount: New amount as specified in the Adjust API.
   • status: Status of the payment. You will also receive the result in a webhook.

3. Wait for the Adjust Payment webhook to learn the outcome of the request.

You can store the id and paymentToken for:

• Retrieving payment details later.
• Voiding the payment (if needed).
• Issuing partial or full refunds.
