Void a Payment

Overview

Voiding reverses a completed payment before it settles — no money moves from the customer’s account to the merchant’s. This is the quickest way to reverse a transaction on the same day, avoiding refund processing fees.

Void vs. Cancel vs. Refund:

• Cancel — payment is still in progress (not yet completed)
• Void — payment completed but not yet settled (same day, before 23:00 UTC)
• Refund — payment has settled (next day or later)

When to Use Void

Scenario	Description
Wrong amount charged	Customer was overcharged, caught same day
Duplicate transaction	Same payment processed twice
Customer changed mind	Immediate post-purchase reversal
Incorrect product	Wrong item charged at point of sale

Step 1: Void the Payment

Call the void endpoint with the paymentId:

POST /payments/:paymentId/void
{}

// Response
{
  "status": "SUCCESS",
  "data": {
    "voidStatus": "VOIDED"
  },
  "message": "Payment voided successfully"
}

Possible voidStatus values: VOID_INITIATED | CANNOT_VOID | VOIDED

Important: Voiding is only possible before 23:00 UTC on the transaction day. After the settlement cutoff, you must process a refund instead.

Step 2: Verify Order Status

Confirm the void was applied:

GET /orders/:orderId/status

The order’s transaction data will show voided: true for the affected transaction.

Handling CANNOT_VOID

If the void returns CANNOT_VOID, the payment has either:

• Already been settled (past 23:00 UTC cutoff)
• Not yet completed (use Cancel instead)

In these cases, process a full refund or partial refund as needed.
