Overview

The Unilateral Scheduled Settlement Instruction Request Self-Service Tool is provided to Payment Providers to act as a Participant to initiate the Unilateral Scheduled Settlement Instruction (USSI) workflow via upload of a configurable CSV file using a cURL command to a REST endpoint, which will be consumed and validated by the CSP.

The REST endpoint translates the CSV file into an ISO XML message (Unilateral Scheduled Settlement Instruction Request (sett_105)) which is then submitted to the CSP.

The Self-Service CSV file must be populated with a Trust Amount where the Settlement Participant is a Broker (i.e. Clearing and Settlement Participant). The Trust Amount provided may be zero, where applicable. If the Trust Amount is populated, the Trust Credit Debit Indicator for the trust amount must also be provided and be one of the following values:

• CRDT (Credit); or

• DBIT (Debit).

Where the Settlement Participant is not a Broker (i.e. Non-Market Settlement Participant), the Trust Amount must not be populated in the CSV file submission. For further details, refer to /wiki/spaces/CSP/pages/23233675.

On successful submission and validation of the CSV file, the CSP sends a Settlement Instruction Response (sett_106) to the Participant. Refer to /wiki/spaces/CSP/pages/23233812 for further information regarding elements present in the CSV file.

If the CSV submitted by the requesting party is invalid due to errors in the business validity, an Invalid Transaction (comm_808) is received.

If the CSV submitted by the requesting party is invalid due to errors in the file format or schema validity, a rejection from the Self-Service Tool is received.

These responses are delivered to the REST endpoint, where they are converted to a JSON response. 

Sample Template

The file below contains an Excel file template which is used to the build the CSV submission to the cURL.

When populating the CSV, the developer is required to ensure:

• The message includes the appropriate fields, as populated in the attached template; and

• Supplied dates are valid business dates.

Connection Details

Prior to establishing connection to the ITE1, Payment Providers will need to generate and submit a Certificate Signing Request and acquire the ASX root / issuing CA public key (instructions are available on the FTP). Payment Providers are also required to populate the CSV sample file above.

The below code snippet demonstrates how to establish connection to the Self-Service Unilateral Scheduled Settlement Instruction Request.

curl
    // Verbose output
    -v
                  
    // ASX’s CA’s public keys in pem format
    --cacert /c/path/to/file.pem
                 
    // File containing the certificate of the client machine
    --cert /c/path/to/file.cer
      
    // Private key of the client certificate provided in cert option
    --key /c/path/to/file.key
              
    // The URL of the Self-Service Tool
    "https://ite1-test-tool.asx.com.au:5000/xmlIngest/sett105ussi"
                  
    // Header option to accept json format (not the same as the CSV file)
    -H "accept: application/json"
                  
    // Header option to tell curl command that it will be form-data in other words file as input
    -H "Content-Type: multipart/form-data"
                  
    // The input CSV file to be sent as part of the request
    -F "file=@/c/path/to/file.csv"
