Create Requests :

To create a new ISO request for a Transformer:

  1. Select the ISO type Transformer and click "New Request" on hover to create a request.
  2. Navigate to the created request & select it to configure.
  3. User will see three tabs L1, L2 & L3. L1 represents dynamically generated transformer request's endpoint, In L2 we provide request & response rules scripts and in L3 we provide client request & response body for client's url.
  • Client url can be any valid url which will return the expected response.
  1. Now in L1 provide necessary data method, body.
  • Port value auto assign to requests when ISO type Transformer starts.
  1. Transformer rules scripts can be applied using L2 tab.
  2. In L3 provide client url, content type, method, body etc.
  • If client content type is ISO then it will need endpoint, port & spec file.
  1. Save the configured request and Start the Transformer.

Execute ISO Request

To test a ISO Transformer request:

  1. Copy the URL of the desired ISO request within the Transformer.
  2. Go to the API module , select ISO tab and Paste the Transformer request's endpoint & port.
  3. Provide any required data (body, method, headers etc).
  4. Send the request.
  5. Compare the actual response to the expected response.
  • Make sure to start the Transformer after simulating a request.

Example :

We will simulate an Payment_processing request in ISO type Processing collection. This request will take ISO type data as L1 & XML type data as L3 In which user will provide JSON payload and internally this request will execute client request with ISO payload data :

L1 request & response body :-

// L1 Request Body

</isomsg>

L3 request & response body :-

  • These below bodies have been used to create L3 request.
  • User can use these body and simulate an L3 ISO request using PruTAN's Hostbox module.-
  • To know how to simulate requests in Hostbox please follow : Hostbox 
// L3 Request Body
<Transaction>
  <MTI>0200</MTI>
  <PrimaryAccountNumber>1234567890123456</PrimaryAccountNumber>
  <ProcessingCode>000000</ProcessingCode>
  <TransactionAmount>1000</TransactionAmount>
  <TransmissionDateTime>0612081234</TransmissionDateTime>
  <SystemsTraceAuditNumber>123456</SystemsTraceAuditNumber>
  <LocalTransactionTime>121234</LocalTransactionTime>
  <LocalTransactionDate>0608</LocalTransactionDate>
  <TerminalId>12345678</TerminalId>
  <CurrencyCode>840</CurrencyCode>
</Transaction>


// L3 Response Body
<Transaction>
  <MTI>0210</MTI>
  <PrimaryAccountNumber>1234567890123456</PrimaryAccountNumber>
  <ProcessingCode>000000</ProcessingCode>
  <TransactionAmount>1000</TransactionAmount>
  <TransmissionDateTime>0612081234</TransmissionDateTime>
  <SystemsTraceAuditNumber>123456</SystemsTraceAuditNumber>
  <LocalTransactionTime>121234</LocalTransactionTime>
  <LocalTransactionDate>0608</LocalTransactionDate>
  <TerminalId>12345678</TerminalId>
  <CurrencyCode>840</CurrencyCode>
  <ResponseCode>00</ResponseCode>
  <ApprovalCode>ABC123</ApprovalCode>
  <Balance>9000</Balance>
</Transaction>

  • Now follow above steps and execute this above simulated request in API module. User will get simulated response body as response after request execution.

  • For a detailed analysis of Transformer requests, users can check the Transformer's Analytics submenu.

  • Repeat these steps for different scenarios within the Transformer to thoroughly test your ISO APIs efficiently.
