PayU-Handled 3DS Authentication
Using PayU 3DS Authentication
To use 3DS authentication, merchants must be registered to this service with PayU. Once registered, you can include a new parameter called req3DSAuthentication in your payment requests via PayU’s Payments API.
Note
3DS authentication for PayU Latam is only available for Argentina, Brazil, Colombia, and Peru.The req3DSAuthentication Parameter
This parameter allows you to control whether 3DS authentication is required for each transaction. It accepts two values:
"true": Enforces 3DS authentication for the transaction."false": Disables 3DS authentication for the transaction.
If req3DSAuthentication is not included, PayU will decide whether to perform 3DS authentication based on its own risk assessment.
Request Example
In the request example below, the req3DSAuthentication is set true:

Testing the 3DS Authentication
To test the 3DS authentication process, use the dummy values provided in the table below. These values are applicable across the different payment methods available in each country:
 Argentina |
 Brazil |
 Colombia |
 Peru |
|
|---|---|---|---|---|
| Account ID | 516684 | 516685 | 516686 | 516688 |
| Merchant ID | 508029 | |||
| API Login | pRRXKOl8ikMmt9u | |||
| API Key | 4Vj8eK4rloUd272L48hsrarnUA | |||
| Public Key | PKaC6H4cEDJD919n705L544kSU | |||
Note
These account IDs are for testing purposes only, do not use them in production environments.Transaction Response and Authentication Flow
Upon sending a payment request, you will receive a response with a "PENDING" state for the transaction. This response will also include a field within extraParameters called THREEDS_AUTH_REDIRECT_URL.
THREEDS_AUTH_REDIRECT_URL: This URL should be used to redirect the payer to complete the 3DS authentication process. The authentication process might involve challenges like entering a one-time password (OTP) received on their phone.
Response Example
In the response example below, the merchant redirects the payer to https://merch-prod.payu.com:
{
"code": "SUCCESS",
"error": null,
"transactionResponse": {
"orderId": 3344440141,
"transactionId": "968d3f37-25aa-4fc2-86bf-0a2eee091713",

}
}
}
After Authentication
Once the payer completes the 3DS authentication (if required), PayU will receive a notification. The transaction will then be:
- Completed: If the authentication is successful.
- Declined: If the authentication fails.
Redirection After Authentication
Following the payer’s redirection from the THREEDS_AUTH_REDIRECT_URL, they will be directed to:
- PayU Checkout transaction status page: By default, this is the behavior if the merchant hasn’t specified a custom return URL.
- Merchant’s custom return URL: If provided, the payer will be redirected to the merchant’s designated page after authentication.
