7. Adding Transactions

If a model works correctly, it will flag a fraudulent transaction and create an alert.

The Unit21 foundation is composed of:
Entities - a user or business
Instruments - an object that is used to exchange currencies
Transactions - two entities that exchange currencies

Before fraud can be monitored, it is important to generate additional transactions for Mr Baker.

Add more Transactions


  1. Log into your Dashboard.
  2. Navigate to the Data Explorer and go to the Upload File tab:
12001200
  1. As per previous section, download this JSON file on your computer. You can highlight the text and copy-paste it into a text editor like Notepad. Save the file as Create_baker_events.json and make sure no extra text is added and that the file extension is JSON and not TXT.

  1. Replace the event_time with the current Unix timestamp (today's date and time) by going to this URL: https://www.epoch101.com/.

     "general_data": {
         "event_id": "baker-transaction-02",
         "event_type": "transaction",
         "event_subtype": "ach",
         "event_time": CURRENT EPOCH GOES HERE
     },
...
 }, {

         "event_id": "baker-transaction-03",
         "event_type": "transaction",
         "event_subtype": "ach",
         "event_time": CURRENT EPOCH GOES HERE
     },
...
 }]

Make sure to replace the event_time for BOTH transactions as this JSON file will create 2 events.

  1. Drag and drop Create_baker_events.json to the Upload File widget.
  2. Make sure the file uploaded correctly, it should be labeled as Awaiting Trigger:
12001200
  1. In the table of Recent Uploads, select the ... menu item (three dots on the right hand side) of your Create_baker_events.json file. Select Process in the menu:
12001200
  1. Patiently wait while Unit21 validates and processes the file.
12001200
  1. Success! You can see the results by navigating to the Transactions tab:
12001200

You may need to use our filters to find the new transaction!

It is important to note here that two transactions were created:

  1. baker-transaction-02: Baker01 and 71c4d7b-0563-aab1-4685 exchanged $13305.89. Baker01 used his credit card *7291.
  2. baker-transaction-03: Lee01 and Baker01 exchanged $17800.00. Baker received the funds on credit card *7291.

Next, we will write a rule to flag these transactions in the system and generate alerts.
