  • Send the name of the transaction status in the name of the cardholder.
    • For approved transactions, send APPROVED value.
    • For rejected transactions, send REJECTED value.

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.
