  How to use this shurjoPay plugin

  To integrate the shurjoPay Payment Gateway in your Java project do the following tasks sequentially.

  Step 1: Add dependency into your java or spring project

  Maven

  <dependency>
    <groupId>bd.com.shurjomukhi</groupId>
    <artifactId>sp-plugin-java</artifactId>
    <version>0.1.0</version>
  </dependency>

  Gradle

  implementation 'bd.com.shurjomukhi:sp-plugin-java:0.1.0'

  Download Jar
  Go to Maven central and download the latest version.
  

Attention: shurjoMukhi offers separate plugin to integrate with any Spring Application.

Step 2: Create shurjopay.properties inside project resource path.

Properties file contains four fields SP_USER, SP_PASS, SHURJOPAY_API, SP_CALLBACK to configure shurjoPay. Configure logging using these params SPLOG_PATH, SPLOG_FILE.

#merchant username and password provided by shurjoPay author
SP_USER = <merchant_username>
SP_PASS = <merchant_password>

#shurjoPay API's base path for sandbox
SHURJOPAY_API = https://sandbox.shurjopayment.com/api

#callback URL is used for cancel payment or success payment
SP_CALLBACK = https://sandbox.shurjopayment.com/response

#shurjoPay plug-in log file location
SPLOG_PATH= /var/log
SPLOG_FILE = sp-java-plugin.log

• See and copy this ready shurjopay.properties.
• Add logback-classic dependency in your application to get log messages generated by this plugin to track shurjoPay errors only (optional).

Step 3: After that, you can initiate payment request to shurjoPay using below code example.

    // Initialize shurjopay
    Shurjopay shurjopay = new Shurjopay();

    // Prepare payment request to initiate payment
    PaymentReq request = new PaymentReq();
    request.setPrefix("sp");
    request.setAmount(10.00);
    request.setCustomerOrderId("sp315689");
    request.setCurrency("BDT");
    request.setCustomerName("Dummy");
    request.setCustomerAddress("Dhaka");
    request.setCustomerPhone("01766666666");
    request.setCustomerCity("Dhaka");
    request.setCustomerPostCode("1212");
    request.setCustomerEmail("[email protected]");

    // Calls first method to initiate a payment
    shurjopay.makePayment(request);

• Returns PaymentRes corresponding this JSON

Step 4: Payment verification can be done after each transaction with shurjopay transaction id.

    shurjopay.verifyPayment(:=spTxnId)

• Returns VerifiedPayment corresponding this JSON

  Congrats! Now you are ready to use the java plugin to seamlessly integrate with shurjoPay to make your payment system easy and smooth.
