Overcapture

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.

Example: API Request

curl --location 'https://sandbox.hyperswitch.io/payments' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'api-key: <your_publishable_key>' \
--data '{
  "amount": 100,
  "currency": "USD",
  "confirm": true,
  "capture_method": "manual",
  "enable_overcapture": true,
}'

Field Semantics

enable_overcapture Indicates merchant intent.

is_overcapture_enabled Indicates connector capability acceptance.

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
