## Overview

The payment data store is used to store payment method data and payment processing information. When the payment status changes, the data store will reflect this.

**⚠️ Currently, all the actions are internal-only while we determine which ones will be useful for extensions to interact with. We do not encourage extensions to dispatch actions onto this data store yet.**

An example of data held within the Payment Data Store is shown below. This example shows the state with several Payment Gateways active, and a saved token.

```js
{
    status: 'idle',
    activePaymentMethod: 'stripe',
    activeSavedToken: '1',
    availablePaymentMethods: {
      bacs: {
        name: 'bacs'
      },
      cheque: {
        name: 'cheque'
      },
      cod: {
        name: 'cod'
      },
      stripe: {
        name: 'stripe'
      }
    },
     availableExpressPaymentMethods: {
      payment_request: {
        name: 'payment_request'
      }
    },
    savedPaymentMethods: {
      cc: [
        {
          method: {
            gateway: 'stripe',
            last4: '4242',
            brand: 'Visa'
          },
          expires: '12/32',
          is_default: true,
          actions: {
            'delete': {
              url: 'https://store.local/checkout/delete-payment-method/1/?_wpnonce=123456',
              name: 'Delete'
            }
          },
          tokenId: 1
        }
      ]
    },
    paymentMethodData: {
      token: '1',
      payment_method: 'stripe',
      'wc-stripe-payment-token': '1',
      isSavedToken: true
    },
    paymentResult: null,
    paymentMethodsInitialized: true,
    expressPaymentMethodsInitialized: true,
    shouldSavePaymentMethod: false
}
```

## Usage

To utilize this store you will import the `PAYMENT_STORE_KEY` in any module referencing it. Assuming `@woocommerce/block-data` is registered as an external pointing to `wc.wcBlocksData` you can import the key via:

```js
const { PAYMENT_STORE_KEY } = window.wc.wcBlocksData;
```

## Selectors

### getState

Returns the current state of the payment store.

> 🚨 Instead of using this selector, the focused selectors should be used. This selector should only be used to mock selectors in our unit tests.

#### _Returns_ <!-- omit in toc -->

-   `object`: The current state of the payment store with the following properties:
   	-  _status_ `string`: The current status of the payment process. Possible values are: `idle`, `started`, `processing`, `ready`, `error`, `success`, `failed`.
   	-  _activePaymentMethod_ `string`: The ID of the active payment method.
   	-  _activeSavedToken_ `string`: The ID of the active saved token.
   	-  _availablePaymentMethods_ `object`: The available payment methods. This is currently just an object keyed by the payment method IDs. Each member contains a `name` entry with the payment method ID as its value.
   	-  _availableExpressPaymentMethods_ `object`: The available express payment methods. This is currently just an object keyed by the payment method IDs. Each member contains a `name` entry with the payment method ID as its value.
   	-  _savedPaymentMethods_ `object`: The saved payment methods for the current customer. This is an object, it will be specific to each payment method. As an example, Stripe's saved tokens are returned like so:
   	- _paymentMethodData_ `object`: The current payment method data. This is specific to each payment method so further details cannot be provided here.
   	- _paymentResult_ `object`: An object with the following properties:
      		- _message_ `string`: The message returned by the payment gateway.
      		- _paymentStatus_ `string`: The status of the payment. Possible values are: `success`, `failure`, `pending`, `error`, `not set`.
      		- _paymentDetails_ `object`: The payment details returned by the payment gateway.
      		- _redirectUrl_ `string`: The URL to redirect to after checkout is complete.
   	- _paymentMethodsInitialized_ `boolean`: True if the payment methods have been initialized, false otherwise.
   	- _expressPaymentMethodsInitialized_ `boolean`: True if the express payment methods have been initialized, false otherwise.
   	- _shouldSavePaymentMethod_ `boolean`: True if the payment method should be saved, false otherwise.

### getActiveSavedToken

#### _Returns_ <!-- omit in toc -->

-   `string`: The active saved token ID, or empty string if a saved token is not selected.

#### _Example_ <!-- omit in toc -->

    },
    "cod": {
        name: "cod",
