Overcapture

Capture amounts greater than the originally authorized amount in manual capture payments

Overview

In card payments, Over Capture occurs when a merchant captures (settles) an amount greater than the originally authorized amount.

This is particularly useful in scenarios such as:

• Additional charges (e.g., shipping, handling, gratuities).

• Price adjustments made after initial authorization.

• Reducing the risk of under-capturing when final order values differ.

Enabling Over Capture

1. Profile-level Configuration (via Dashboard)

• Navigate to: Developer → Payment Settings → Always Enable Over Capture

• Toggle Enable/Disable as required.

2. Per-request Configuration (via API)

Use the boolean field enable_overcapture in your payment request.

This can be passed in:

POST /payments

POST /payments/:id/update

Note:

• The request-level enable_overcapture will override the profile-level setting.

• Over Capture is only applicable for manual capture payments i.e. capture_method = manual.

Monitoring & Settlement

• After authorization, merchants can view the amount_capturable field (under More Payment Details) to see the maximum amount that can be captured.

• Once the payment is captured (or overcaptured), the final amount will be reflected in the amount_received field.

Merchant Action

• Use Dashboard settings for global enablement

• Use API overrides for payment-specific enablement

• Monitor capturable and received amounts to track final settlements
