Collect Payments - Save Card

When your customer has an account on your shopping website, they may store their card details to use when they revisit your website (repeat payment).

Steps to Integrate:

  1. [Get the saved card details of a customer]
  2. [Post the payment to PayU using _payment API]
  3. [Check the PayU Response]
  4. [Verify the payment]

PayU offers you API to save the card details and retrieves them using the Store Card APIs. For example, the stored cards are displayed when your customer performs checkout and lands on the payment page, similar to the following screenshot where they need to enter only the CVV:

This section explains the procedure for getting a customer’s card details and using a saved card to initiate payment.

Step 1: Get the Saved Card Details

  1. Get the customer’s card details your merchant key and customer’s registered mail ID to PayU using the get_user_details API:
curl -X POST "https://test.payu.in/merchant/postservice?form=2"-H "accept: application/json" -H "Content-Type: application/x-www-form-urlencoded" -d"key=J****g&command=get_user_cards&var1=yourkey:[email protected]&hash=22744b991e9719a9823ee71832e37b022a77fce4d53188245114226d0d0d3a01ec0b6adce4aae9b9bd97baf97e3ef76912e29ca0726a57b16c1110dc66ffc653"

import requestsurl = "https://test.payu.in/merchant/postservice?form=2"payload = "key=J****g&command=get_user_cards&var1=yourkey:[email protected]&hash=22744b991e9719a9823ee71832e37b022a77fce4d53188245114226d0d0d3a01ec0b6adce4aae9b9bd97baf97e3ef76912e29ca0726a57b16c1110dc66ffc653"headers = { "Accept": "application/json", "Content-Type": "application/x-www-form-urlencoded" }response = requests.request("POST", url, data=payload, headers=headers, params=querystring)print(response.text)

import requestsurl = "https://test.payu.in/merchant/postservice?form=2"payload = "key=JP***g&command=get_user_cards&var1=yourkey:[email protected]&hash=22744b991e9719a9823ee71832e37b022a77fce4d53188245114226d0d0d3a01ec0b6adce4aae9b9bd97baf97e3ef76912e29ca0726a57b16c1110dc66ffc653"headers = { "Accept": "application/json", "Content-Type": "application/x-www-form-urlencoded" }response = requests.request("POST", url, data=payload, headers=headers, params=querystring)print(response.text)

Request request = Request.Post("https://test.payu.in/merchant/postservice?form=2 -H");String body = "key=J****g&command=get_user_cards&var1=yourkey:[email protected]&var2=&var3=&var4=&var5=&var6=&var7=&var8=&var9=&hash=22744b991e9719a9823ee71832e37b022a77fce4d53188245114226d0d0d3a01ec0b6adce4aae9b9bd97baf97e3ef76912e29ca0726a57b16c1110dc66ffc653"request.bodyString(body,ContentType.APPLICATION_FORM_URLENCODED);request.setHeader("Content-Type", "application/x-www-form-urlencoded");HttpResponse httpResponse = request.execute().returnResponse();System.out.println(httpResponse.getStatusLine());if (httpResponse.getEntity() != null) {String html = EntityUtils.toString(httpResponse.getEntity());System.out.println(html);}
  1. Check the response for the last four digits of the card number:
{
      "status": 1,
      "msg": "Cards fetched Succesfully",
      "user_cards": {
            "57cb996f2eaeee525765a": {
                  "expiry_month": "03",
                  "card_mode": "CC",
                  "is_expired": 0,
                  "card_cvv": 0,
                  "card_no": "XXXXXXXXXXXX2346",
                  "card_token": "57cb996f2eaeee525765a",
                  "card_name": "test card",
                  "card_type": "CC",
                  "expiry_year": "2026",
                  "name_on_card": "Test",
                  "card_brand": "MASTERCARD",
                  "card_bin": "512345",
                  "isDomestic": "Y"
            }
      }
