Integration widget

How to integrate our widget to make payments and access end user banking information

Embedding quickstart

To start using the widget, its necessary to include the script tag with our initialization script:

<script src=""></script>

The widget has to be initialized with it's id (configured in the administration dashboard)

var widget = Prometeo.init('widget-id');

And then we can start registering event listeners:

widget.on(Prometeo.Messaging.LOGIN, (session) => {
	console.log('Event: LOGIN');

widget.on(Prometeo.Messaging.GET_ACCOUNTS, (accounts) => {
	console.log('Event: GET_ACCOUNTS');
	console.log(`accounts: ${accounts}`);

Finally we call open() to show the widget to the user, with necessary payment information{
  allowedFeatureLevel: 2, 
  currency: 'PEN', 
  amount: 12.34,
  concept: "Order 1234"

Here we use the following parameters:

  • allowedFeatureLevel with a value of 2 to indicate we are starting a payment flow
  • currency is the currency used for the payment in ISO 4217 format, in this case we use PEN for Peruvian Sol.
  • amount is the payment amount.
  • concept is the payment concept or reference.

    <script src=""></script>
    <button onclick="openWidget()">SHOW WIDGET</button>
      var widget = Prometeo.init('widget-id');

      widget.on(Prometeo.Messaging.CLOSE, () => {
        console.log('Event: CLOSE');

      widget.on(Prometeo.Messaging.LOGIN, (session) => {
        console.log('Event: LOGIN');

      widget.on(Prometeo.Messaging.GET_OWNER_INFO, (ownerInfo) => {
        console.log('Event: GET_OWNER_INFO');
        console.log(`ownerInfo: ${ownerInfo}`);

      widget.on(Prometeo.Messaging.GET_ACCOUNTS, (accounts) => {
        console.log('Event: GET_ACCOUNTS');
        console.log(`accounts: ${accounts}`);

      widget.on(Prometeo.Messaging.ERROR, (error) => {
        console.log('Event: ERROR');
        console.log(`error: ${error}`);

      widget.on(Prometeo.Messaging.PAYMENT_SUCCESS, (payload) => {
        console.log('Event: PAYMENT_SUCCESS');
        console.log(`payload: ${payload}`);

      const openWidget = () => {{allowedFeatureLevel: 2, currency: 'PEN', amount: 1, concept: "Order 1234"});
