# PaymentMethodApi


You can use the APIs below to interface with Xendit's `PaymentMethodApi`.
To start using the API, you need to configure the secret key and initiate the client instance.

```php
<?php
require_once(__DIR__ . '/vendor/autoload.php');

use Xendit\Configuration;
use Xendit\PaymentMethod\PaymentMethodApi;

Configuration::setXenditKey("YOUR_API_KEY_HERE");

$apiInstance = new PaymentMethodApi();
```

All URIs are relative to https://api.xendit.co, except if the operation defines another base path.

## Callback Objects
Use the following callback objects provided by Xendit to receive callbacks (also known as webhooks) that Xendit sends you on events, such as successful payments. Note that the example is meant to illustrate the contents of the callback object -- you will not need to instantiate these objects in practice
### PaymentMethodCallback Object
>Callback for active or expired E-Wallet or Direct Debit account linking, Virtual Accounts or QR strings

Model Documentation: [PaymentMethodCallback](/PaymentMethodCallback.md)
#### Usage Example
Note that the example is meant to illustrate the contents of the callback object -- you will not need to instantiate these objects in practice
```php
<?php
require_once(__DIR__ . '/vendor/autoload.php');

use Xendit\PaymentMethod\PaymentMethodCallback;

$payment_method_callback = new PaymentMethodCallback([
  'event' => 'payment_method.activated',
  'data' => [
    'id' => 'pm-6ff0b6f2-f5de-457f-b08f-bc98fbae485a',
    'card' => null,
    'type' => 'DIRECT_DEBIT',
    'status' => 'ACTIVE',
    'country' => 'PH',
    'created' => '2022-08-12T13=>30=>26.579048Z',
    'ewallet' => null,
    'qr_code' => null,
    'updated' => '2022-08-12T13=>30=>58.908220358Z',
    'metadata' => null,
    'customer_id' => 'e2878b4c-d57e-4a2c-922d-c0313c2800a3',
    'description' => null,
    'reusability' => 'MULTIPLE_USE',
    'direct_debit' => [
      'type' => 'BANK_ACCOUNT',
      'debit_card' => null,
      'bank_account' => [
        'bank_account_hash' => 'b4dfa99c9b60c77f2e3962b73c098945',
        'masked_bank_account_number' => 'XXXXXX1234'
      ],
      'channel_code' => 'BPI',
      'channel_properties' => [
        'failure_return_url' => 'https://your-redirect-website.com/failure',
        'success_return_url' => 'https://your-redirect-website.com/success'
      ]
    ],
    'failure_code' => null,
    'reference_id' => '620b9df4-fe69-4bfd-b9d4-5cba6861db8a',
    'virtual_account' => null,
    'over_the_counter' => null,
    'billing_information' => null,
    'direct_bank_transfer' => null
  ],
  'created' => '2022-08-12T13=>30=>59.074277334Z',
  'business_id' => '5f27a14a9bf05c73dd040bc8'
]);
```

You may then use the callback object in your webhook or callback handler like so,
```php
<?php
require_once(__DIR__ . '/vendor/autoload.php');

function simulatePaymentMethodCallback(PaymentMethodCallback $payment_method_callback) {
    echo $payment_method_callback->getId();
    // do things here with the callback
}
```
