Setu Java SDK

SDK to help Java developers integrate with Setu APIs.

Currently the following APIs are supported :

• UPI Deeplinks

The package is under development so stay tuned for changes.

Installation

Usage

UPI Deeplinks

The following actions are currenly supported :

• Generate new payment link
• Check status of payment

Generate new payment link

Create an instance of SetuRequestHelper and add the required parameters to it as shown.

final SetuRequestHelper helper = new SetuRequestHelper(
   schemeId, // unique id 
   secret, // unique key
   productInstance, // unique product instance
   isProduction // determines sandbox or prod environment
);

To generate the link, call the method generateLink() on the above created object. The method returns an object of type GenerateLinkResponse, to get relevant data from the request use the getters defined in the class as follows. The method contains the following arguments in order:

• Integer amount -> Bill amount in paisa
• Integer expiresInDays -> Teh deeplink is created on the time of request and we can monitor its validity in the given time frame // optional
• String payeeName -> Details of the customer // optional
• String refId -> Biller's bill ID
• String exactness -> Amount exactness, can be EXACT, EXACT_UP or EXACT_DOWN

final GenerateLinkResponse res = helper.generateLink(10000, 20, "Test Name", "billerID1234", "EXACT")

The following success JSON is converted to the GenerateLinkResponse object.

{
 "status" : "",
 "success" : true,
 "data":{
   "name" : "",
   "platformBillID" : "",
   "paymentLink" : {
     "shortURL" : "",
     "upiID" : "",
     "upiLink" : ""
   }
  }
}

The following getters can be used on the object to get relevant data.

getStatus() // -> String
getSuccess() // -> Boolean
getName() // -> String
getUpiId() // -> String 
getPlatformBillId() // -> String 
getError() // -> DeeplinkError

Check Status

The deeplink generated can be checked with this method, it gives information about the status of the payment. From the helper call the method checkStatus(). It takes the parameter of platformBillID which is returned when link is generated for the first time. The success response is in the given JSON format

 {
 "status" : "",
 "success" : true,
 "data":{
   "name" : "",
   "createdAt" : "",
   "expiresAt" : "",
   "platformBillID" : "",
   "status" : "",
   "paymentLink" : {
     "shortURL" : "",
     "upiID" : "",
     "upiLink" : ""
   }
  }
}

The above JSON is converted to the object of type CheckStatusResponse and we can get relevant data from the following getters

getRequestStatus() // -> String
getSuccess() // -> Boolean
getCreatedAt() // -> String
getExpiresAt() // -> String
getName() // -> String
getUpiId() // -> String
getUpiLink() // -> String
getPlatformBillID() // -> String
getError() // -> DeeplinkError

Mock Payment (only in sandbox mode)

Mock payment allows us to test the system in sandbox environment. On the helper call the method mockPayment(). It takes 2 arguments :

• Integer amount - Amount in paisa
• String UpiId of the biller (this is received in the status response)

The response returns nothing so we use the status code and provide a String to give feedback to the user. On a successful mock payment we get Mock Success string in the console else RequestException is thrown with status code from the server.

DeeplinkError Object

DeeplinkError object has the following members :

   private final String code;
   private final String detail;
   private final String docURL;
   private final String title;
   private final List<String> errors;
   private final String traceId;

This object is not accessible outside the package so to get info related to the error use the getters available withing the response objects.
