Testing status

When testing Payments, you must send in the request:

  • To get approved transactions:
    • Send APPROVED in the name of the cardholder.
    • Send 777 in the CVV of the card (for AMEX, use 7777).
    • The test parameter and the description also define the state. If it doesn’t work with test set as false, change its value to true.
    • Send the month of the expiration date of the card less than 6 and the year must be 2023 or higher. Example: 05/2025.
  • To get declined transactions:
    • Send REJECTED in the name of the cardholder.
    • Send 666 in the CVV of the card (for AMEX, use 6666).
    • The test parameter and the description also define the state. If it doesn’t work with test set as false, change its value to true.
    • Send the month of the expiration date of the card higher than 6 and the year must be 2023 or higher. Example: 07/2027.
  • For the card number you must enter a valid number, corresponding to the franchise sent in the request. You can use an online card generator for testing purposes or use one of the cards available for your country mentioned before.
  • To test PSE bank transfers (Available in Colombia) in the PayU Sandbox environment, see the PSE Test Guide (PDF).
  • To test cards in Chile, use the cardholder name, CVV and expiration date displayed in the example cards.

Importing the Collection

Click the button below to import our collection in Postman (you may need to refresh the page if the button does not work for you). Note that we create a new environment each time you import the collection.

After you run the collection, you need to set the environment variables and the globals.

Setting your Environment Variables

Our collection has one environment named PayU API Sandbox. We recommend you invoke the collection’s API requests in a Sandbox environment only.

If you want to change the PayU’s testing accounts, configure the api_key, api_login, merchant_id and account-[country] variables. You can leave all the other variables unchanged.

Importing globals

Globals are the variables required to process transactions in our Payment gateway such as currency, transaction amount, confirmation and response pages and more.

Import the globals for the collection to configure the values sent to the requests.

  1. Download the globals file here.

  2. In the Postman collection, click Import next to your workspace name and locate the json file recently downloaded.

  3. When finish, click Import.

To change the amount of a transaction, update the value for the tx_value_[Country] according to the country you want to test.

Running the Requests in the Correct Order

Beware that the order in which you run the requests is important, since some of the data returned by one request may be used in the next invocation.
