Standalone Auth, Capture & Reversal

Overview

PayGlocal offers three standalone API services for merchants who need fine-grained control over the payment lifecycle:

Service	Purpose
Authorization	Request a payment authorization from the issuer
Capture	Capture an authorized payment to trigger settlement
Reversal	Reverse (void) an authorized payment before capture

These APIs are available only when your MID is configured for authentication-only processing through the GPI service. In this model, GPI handles 3DS authentication, and you manage authorization and capture separately. Contact PayGlocal merchant support to configure this on your account.

Authorization

Request a standalone authorization through PayGlocal after completing 3DS authentication via GPI.

Endpoint

POST /gl/v1/payments/auth

Request

For countries requiring authentication before authorization, include the authenticationData block with the ECI and CAVV values received from the authentication process.

    "addressStateCode": "NY",
    "addressPostalCode": "98109",
    "addressCountry": "US",
    "emailId": "example@gmail.com"
  }
}

Response

{
  "gid": "gl-13bbd3c4-9817-4786-96c6-12fa6191f118",
  "status": "AUTHORIZED",
  "message": "Authorization Successful",
  "timestamp": "2021-04-12T07:47:18Z"
}

Store the GID — you will use it in the Capture or Reversal request.

Capture

Capture a previously authorized payment to trigger settlement. You must capture within the authorization window allowed by the card network (typically 7 days).

Endpoint

POST /gl/v1/payments/{gid}/capture

{gid} = the GID returned in the Authorization response.

Request

{
  "merchantTxnId": "23AEE8CB6B62EE2AF07",
  "paymentData": {
    "totalAmount": "100.00"
  },
  "captureType": "F"
}

Request Fields

Field	Type	Required	Description
`merchantTxnId`	String	Yes	Your unique reference for this capture
`paymentData.totalAmount`	String	Yes	Amount to capture
`captureType`	String	Yes	`F` = Full capture, `P` = Partial capture

Reversal (Auth Reversal)

Reverse an authorized payment that has not yet been captured. Only full reversals are supported.

Endpoint

POST /gl/v1/payments/{gid}/auth-reversal

{gid} = the GID returned in the Authorization response.

Request

{
  "merchantTxnId": "23AEE8CB6B62EE2AF07"
}
