Netcash offers a web service called ‘NIWS_NIF’ used to send batched Debit Order files to a Netcash account and then the National Payment System

Technical Information

Before submitting a Compact File, the Netcash Debit Order Masterfile on must already contain the banking information recognised against the Account Reference (101) you are submitting in the file. If there is no entry in the Netcash Debit Order Masterfile for Account Reference (101) this transaction line will fail on upload.

NIWS_NIF is an asynchronous web service which exposes multiple methods. The method BatchFileUpload allows an external system to submit a batch file of Debit orders (Same day / Two day) for processing.

Netcash is compliant with the Payment Card Industry Data Security Standards (PCI DSS) and does therefore not accept or store Credit Card numbers. Only tokens representing the card details and masked credit card numbers (for tracing purposes) may be submitted in this file. The system will reject any file which contains unmasked credit card numbers.

The Service

Object Name Description
method BatchFileUpload


  • ServiceKey (Debit order service key)
  • File (Built in external system)
method RequestFileUploadReport


  • ServiceKey (Debit order service key)
  • FileToken (received on file upload if successful)

Once you have built the file call:

  • Web service: https://ws.netcash.co.za/NIWS/niws_nif.svc
  • Method: BatchFileUpload
  • Service key: Debit order service key


Requests to the web service are sent as strings

The BatchFileUpload method requires two parameters: –

  • Service key (to authenticate the method call)
  • File (the batch file containing the debit order instructions)



public string BatchFileUpload(string ServiceKey, string File) {
  // initialise client
  NIWS_NIF.NIWS_NIFClient client = new NIWS_NIF.NIWS_NIFClient();

  // call the BatchFileUpload method equal to a string variable
  string Request = client.BatchFileUpload(ServiceKey, File);

  // close client after response is received

  switch (Request) {
    case "100":  // Authentication failure
    case "102":  // Parameter error
    case "200":  // General code exception.
    default:  // successful
      return Request;

  // use response to call RequestFileUploadReport method
  return Request;




Successful request

If the method call was successful and the file is being processed, the web service will return a file token which is used to retrieve the load report

Example:  20000000.2550236530.0483.2.2


Unsuccessful request

If the method call fails, the web service will return an error code:

Code Description
100 Authentication failure. Ensure that the service key in the method call is correct
101 Date format error. If the string contains a date, it should be in the format CCYYMMDD
102 Parameter error. One or more of the parameters in the string is incorrect
200 General code exception. Please contact Netcash Technical Support.

Input File Structure

The file is a tab delimited text file and has the following mandatory records:

H – Header record identifies the upload and passes instructions to the Netcash server to determine the purpose of the file.
K – Key record must follow the header record. The key record describes the transaction records which follow. The format defined in the key record is used to validate the record structure and content.
T – Transaction records follow the key record. The fields in the transaction records must conform to the layout defined in the key.
F – Footer record must be the last record in the file and confirms that the file is complete.

Header record (H)

Every file must contain a header record as the first record in the file.

Field Name Type Value
1 Record Identifier AN H
2 Service Key AN Debit Order Service Key
3 Version AN 1
4 Instruction AN Purpose of the file
5 Batch name AN Your identifier
6 Action date N CCYYMMDD
7 Software vendor code AN The key is issued by Netcash to identify the software origin of transactions. (only used by Netcash ISV‘s else use the default value: 24ade73c-98cf-47b3-99be-cc7b867b3080)

Field explanations

Field Explanation
Record Id “H” – Identifies the record as a header
Service key Debit Order service key
Version “1” – This is the Netcash version of the file specification
Instruction Update – update the master file without loading a batch
CompactSameday – Sameday batch upload (ideal for once off collection where the time the recipient is debited, is not important)
CompactTwoDay – Dated debit order batch upload (ideal for recurring billing)
Refer to service cutoff times below
Batch name Use this field as an identifier of your batch.
Action date The date on which the payments are to be made to the beneficiary.
Software vendor code This is a code issued by Netcash.

Key Record (K)

  • The key record is mandatory and must appear in the file between the header record and the transaction records.
  • The key defines the content, order and length of the transactions records in the file. It can be likened to the column headings in a spreadsheet.
  • The key lists all the possible fields contained in the subsequent transaction records, even if not every transaction record contains data in all the fields.
  • While the file is customizable, it is recommended that keys are listed in ascending numerical order for ease of debugging and support.


K 101 162


Transaction Record (T)

  • There must be at least one transaction record in the file.
  • The transaction records must conform to the order of the fields as described in the key record.
    (In the example above, the account reference (field id 101) is defined as the first field in the record therefore every transaction record MUST have the account reference as the first field or it will fail validation)
  • Every transaction record must have the same number of fields as defined in the key record (K).
  • Empty fields should be replaced by a blank tab or a default value, where one has been defined.
    Where fields are left empty, the Netcash system will assume spaces or zeroes for fields defined in the key record.


T Acc001 100


Mandatory field

The fields indicated by are mandatory for the specified instruction.

Key Field name Update CompactTwoDay/CompactSameday
101 Account reference
162 Amount

IMPORTANT Any masterfile records included in a batch file upload instruction will automatically be marked as “Active” on the relevant masterfile.

Footer record (F)

The footer record indicates that the complete file has been received. It must be the last record in the file. If the record is not present, the system will fail the file without processing any transaction records.


Field Name Type Value
1 Record Identifier AN F
2 No of transactions N A count of the transaction records
3 Sum of amounts N The sum of the monetary fields (in cents)
4 End-of-file indicator N 9999

Field explanations

Field Explanation
Record Identifier “F” – Identifies the record as a footer
No of transactions This is the count of all the ‘T’ records in the file.
Sum of amounts This is the sum of all the values in the 161 fields.
If field 161 is not specified in the key record, this will be the sum of all the 162 fields.
End-of-file indicator ‘9999’ – Indicates there are no more records.

Retrieving the Load Report

Postback option

If you have activated the postback option in your NetConnector profile, the load report is automatically posted back to the URL you supplied.

Polling option

If you have not activated the postback option, you will need to request the load report using the file token received from the BatchFileUpload method call.

Using the file token, call:

Requests to the web service are sent as strings



public string RequestFileUploadReport(string ServiceKey, string FileToken) {
  // initialise client
  NIWS_NIF.NIWS_NIFClient client = new NIWS_NIF.NIWS_NIFClient();

  // call the RequestFileUploadReport method equal to a string variable
  // the same service key used for the bactch file upload
  string Request = client.RequestFileUploadReport(ServiceKey, FileToken);

  // close client after response is received

  // use response to output to UI
  // service will respond with the result of the file uploaded
  return Request;
