To launch EDGE Connect from your web application, include ninjafetch.js in the HTML and call NinjaFetchWidget.mount() from JavaScript.

1. Import ninjafetch.js

Add this line to your HTML code.

<script type='text/javascript'
src="https://ninjafetch.com/v1/ninjafetch.js"></script>

2. Add a container

You can apply custom styles to the container element to change the position of the widget.

<div id="widgetContainer"/>

3. Add JavaScript code

<script>
    function launch() {
        //Build consumer data
        var consumerData = {
            access_token: 'eyJhbGciOiJIUzI1NiJ9.eyJjbGllbnRf...',
            container_id: 'widgetContainer',

4. Handle Initialization Errors

   //Initialize widget
   try{
       NinjaFetchWidget.mount(consumerData)
   }
   catch(err){
       //Handle mounting errors here
       console.log(err)
   }

The widget will validate the data and throw validation errors. The client application will need to correct the data being passed into the widget and retry.

Example

{
 "message": "Invalid data",
 "fields": {
 	<field 1>: <value 1>,
 	<field 2>: <value 2>
}

5. Handling Callbacks

The Widget will send results back through the three callback functions: onSuccess(), onError(), and onClose().

5.1 onSuccess()

The widget will invoke a first callback once the consumer successfully connects a bank. The callback will have the ibv_report_status value set to “initiated”. Clients who do not make real-time decisions should unmount the widget after the first callback, so the consumer does not need to wait while the EDGE Connect platform downloads transactions and creates the report.

{
    “ibv_report”: “https://ninjafetch.com/api/v1/ibv/requests/IBVF15CE1FD5FADC7663604”,
    “product_request_id”: “IBVF15CE1FD5FADC7663604",
    “ibv_report_status”: “initiated”,
    “ibv_connection_link”: “https://ninjafetch.com/connect/a06bbd625a”
}

The widget will invoke a second callback once the EDGE report is complete. Ibv_report_status will be ”complete”. Only clients who make real-time decisioning based on the EDGE report should wait for the second callback. The returned product_request_id is the unique identifier of the EDGE report, available for download via backend APIs.

{
    “product_request_id”: “IBVF15CE1FD5FADC7663604",
    “ibv_report”: “https://ninjafetch.com/api/v1/ibv/requests/IBVF15CE1FD5FADC7663604”,
    “ibv_report_status”: “complete”
}

5.2 onError()

Called when a technical error occurs. The actual error message will be passed to the callback function.

There is a flag in the parameters called isLastVendor. Unmount the Widget and proceed to error handling only when isLastVendor is true. The consumer can attempt connections with a different IBV aggregator when isLastVendor is false.

{
    "message": "Network error",
    "isLastVendor": false
}

Possible error messages:

Message	Description
Generation failed	Failed to generate features or scores due to corrupted data etc
Pull process timed out	It’s taking longer than the timeout limit to download IBV data using the connection. Default timeout is 5 minutes. The backend will keep attempting data download for up to 30 minutes.
Other Technical Message	Actual technical error message

5.3 onClose()

Reserved for future features.

6. Handle Data Pull Timeout

After the Consumer connects their bank accounts, a backend process will start to download IBV data through the connection.

Usually, this step takes less than 2 minutes to complete. However, depending on the quality of the data aggregator’s bank connection, it may take a few tries and up to 30 minutes for the EDGE Connect platform to acquire the data. By default, the EDGE Connect widget will send a timeout callback to the onError() function and unmount itself after 5 minutes.

The Client can change the timeout by passing a custom data_pull_timeout value to the widget to optimize the user experience. The Client can either try to download the report at a later time (it is recommended to wait for at least 2 minutes before the next attempt), or implement Webhooks to receive updates from the EDGE Connect platform.

When the Client recognizes a timeout it may make any number of retry attempts, which should eventually lead to one of the following responses:

IBV Report - HTTP 200
IBV Report Pending - HTTP 202

7. Report download

After receiving the product_request_id from the widget, the Client application backend can retrieve the full report with a GET to the [/ibv/requests/{request id}](/ibv/requests/{request id}) endpoint. Refer to the IBV Product API Specification document for details about interacting with the API.
