Extension Fee Payment Notification

Summary

service: extension

This web service currently provides two (2) helper methods and two (2) main methods: (details in the table 1.0 below).

The main methods are the basic methods required by a Vendor(bank/agency/company receiving extension fees on behalf of the University) to connect, get student Invoice, send advice and check notification of payment.

Other helper methods have been added for your convenience.

Note

  1. There is a token which will be returned to you after a successful handshake using the ping method. Please use this token for all subsequent calls to the API until it expires.
  2. You can always get another token using your API Key to call ping without passing the token. Authentication is done at host level. It is expected that each request will come from a limited set of known hosts in order to limit access to only known hosts and therefore increase reliability. Your remote ip address will therefore be logged and authenticated by the system each time you make a request to our system.
  3. Encryption is based on http over secure service layer.
  4. The LIVE and TEST endpoints have been communicated with your service integeration team. The maximum length of time you can expect data you generate to persist on the test server is at most one week from the latest Friday.
  5. All request parameter names (userName, password, apiKey, token and invoiceNo) are CaSE SenSitiVe*.

Postman

  1. The service is currently running on the endpoint so you can test once you have received a valid API Key. It is recommended that you familiarise yourself with the integration

Examples

All requests to the server are made as POST requests. An example of making your first call to get the API key to the test server. For example, using the TEST server:

curl --location --request POST 'https://TEST/' \
--form 'userName=<YOUR_USERNAME>' \
--form 'password=<YOUR_PASSWORD>' \
--form 'action=getApiKey' \
--form 'service=extension'

With the response:

{
    "code": 1,
    "message": "",
    "records": 1,
    "data": {
        "apiKey": "201604629514a88fc3....",
        "message": "API Key generated successfully!"
    }
}

NB: Each of the methods described in the table will be passed as a value for action with the service: extension for all extension fee related methods.

Another example of pinging the server with the retrieved API key is as follows:

curl --location --request POST 'https://TEST/' \
--form 'action=ping' \
--form 'service=extension' \
--form 'apiKey=20158010808468caa5...'

With the response below:

{
    "code": 1,
    "message": "You have pinged!",
    "records": 1,
    "data": {
        "message": "Login Successful",
        "token": "<THE_RETURNED_TOKEN_HERE>"
    }
}

  1. This call returns a new apiKey each time it is called. Be sure to save your key to be used in future communications. ↩

  2. The following are the possible transaction state that can be passed with an advice

    1. ACT: This transaction is currently active and has not completed its lifecycle
    2. CLR: Transaction has been cleard. Not likely to receive any further updates
    3. FLD: Transaction failed
    4. COM: Transaction has completed but is not yet cleared
