Assembly Payments Callback Objects
==================================

[](#assembly-payments-callback-objects)

A structured set of objects designed to enable some abstraction handling of [Assembly Payments Callback](https://docs.assemblypayments.com/feature-guides/guides/callbacks/) payloads.

Install
-------

[](#install)

```
composer require assembly-callback
```

Usage Example
-------------

[](#usage-example)

### Basic Usage

[](#basic-usage)

Basic usage simply instantiates a new Callback object of the type provided by your listener.

```
use Assembly\Callback;

// get the request body in your preferred way
$requestBody = file_get_contents("php://input");

// use the factory to create an object of the proper type
$callback = Callback\CallbackFactory::factory($requestBody);
```

### With Payload Validation

[](#with-payload-validation)

You may optionally use the validation feature which requires the availability of the [stock SDK](https://github.com/PromisePay/promisepay-php) by default. This uses the `id` from the callback payload to request the same object from the Assembly API according the the object type.

```
use Assembly\Callback;
use PromisePay\PromisePay;

// get the request body in your preferred way
$requestBody = file_get_contents("php://input");

// use the factory to create an object of the proper type
$callback = Callback\CallbackFactory::factory($requestBody);

// config the PromisePay client
PromisePay::Configuration()->environment('prelive');
PromisePay::Configuration()->login('');
PromisePay::Configuration()->password('');

// validate the callback
$callback->validate();
```

### Extend a Callback Type

[](#extend-a-callback-type)

You may want to add some functionality to an object. To do that, you can define your own type handler.

#### Example extension

[](#example-extension)

```
use Assembly\Callback\Transaction;

class MyTransaction extends Transaction
{
    public function someSpecialHandling() {
        // do something extra special
    }
}
```

#### Use the extension

[](#use-the-extension)

```
use Assembly\Callback;

// get the request body in your preferred way
$requestBody = file_get_contents("php://input");

// when the type is "transactions", use this extention
Callback\CallbackFactory::registerType(
    'transactions',
    'My_Assembly_Callback_Transaction'
);

// use the factory to create an object of the proper type
$callback = Callback\CallbackFactory::factory($requestBody);
```
