Payment Initiation Service (PIS) UI Component

Overview

The Payment Initiation Service (PIS) is an embeddable UI Component that is initiated to fund a payment run from a linked bank account. When initiating the PIS UI Component, users will be prompted to:

Consent a Payment : The end-user needs to consent for a single funding request. The funding information will be displayed in the component.

Sweeping Consent

When a linked account is used for the first time, the user will also be prompted to sweep funds from their zero balance account back to their linked account.

Embed the PIS UI Component

The PIS UI Component requires the below parameters in order to be initialized successfully.

tip

To use Weavr UI components, you must first set up the Weavr UI library in your application and ensure that you have an authentication token set as per instruction.

pis(reference, callbackUrl, state, options);

Parameter	Type	Required?	Description
`reference`	string	Required	The group reference returned from the fund endpoint.
`callbackUrl`	string	Required	The callback URL specifies where the user should be redirected after they have completed their journey on bank website.
`state`	string	Required	This property can be used to pass a string or serialised data which will be appended to your configured default callback URL.
`options`	object	Optional	Add styling to the component.

important

The callbackURL must be on the same domain as the Redirect URL configured in the portal.

const pis = weavrComponents.prompt.pis(reference, callbackUrl, state, options);

Mounting

To display the component on the screen, it's necessary to mount it to the DOM. This involves creating a wrapping element that will serve as the container for injecting the secure frame. Be sure to assign an id to the HTML element.

note

Upon mounting to the element target the component will immediately call the necessary API’s in order to populate the necessary data on screen.

<!--pis.html-->
<div id="pis-example"></div>

// secure-pis.js
const pis = weavrComponents.prompt.pis(reference, callbackUrl, state, options);
pis.mount("#pis-example");

Look and feel

The options parameter manages the overall appearance of the component. The below defines the options object:

Property	Type	Required?	Description
`classNames`	object	Optional	Defines which classes are to be appended to the wrapping element.
`style`	object	Optional	Defines the look and feel of the components elements.

Functions

You can interact with the library's components by utilizing the exposed functions. The below is a list of functions exposed for the PIS component

`mount`

The mount function is called in order to mount a component into the defined selector.

pis.mount(selector);

`unmount`

The unmount function is called in order to unmount a component from its selector.

note

Once a component is unmounted it can be remounted. One can remount the component utilizing the mount function.

pis.unmount();

`destroy`

The destroy function can be used to remove the element and its references from the DOM.

note

Once a component is destroyed it cannot be remounted. The component will be removed from Document Object Model (DOM) alongside any references and will need to be re-initialised

pis.destroy();

`on`

This function makes event listeners available for interacting with the component during events.

pis.on(event, listener);

`off`

This function provides the capability to detach event listeners from the component.

pis.off(event, listener);

Events

The PIS component will trigger the following events. You can listen to these events by attaching event listeners.

Event	Trigger condition
`ready`	Component has been initialisation successfully.
`change`	When component's state changes.
`error`	An error is returned during API requests. If not handled, an error is returned.
`accept`	Triggered when the PIS Consent is fulfilled.
`decline`	Triggered the decline button is clicked.

// Example - decline for accept event
pis.on("accept", (event) => {
  // do something
});

// Example - listen for error event
pis.on("error", (event) => {
  // do something
});
