Installing

edit your composer with the bundle library and version

composer require borsaco/coinbase-bundle

Development

You can get the handler inside your Controller and call the functions

Create new Charge

Let's create a new charge along with $3.6 donation. The input can be json array, json string or Charge object

CALL WITH JSON ARRAY

   use Borsaco\CoinbaseBundle\Handler\CoinbaseHandler;

   /**
    * @Route("/acceptcrypto/", name="acceptcrypto")
    */
    public function acceptDonation(CoinbaseHandler $coinbaseHandler){
        $amount = 3.6;//$3.6 dollars
        $json =  [
           "name" => "Cancer Donation Box",
           "description" => "Donate to Children",
           "local_price" => array("amount" => $amount, "currency" => "USD"),
           "pricing_type" => "fixed_price",
           "metadata" => array("id" => "1234", "firstname" => "John", "lastname" => "Doe", "email" => "jdoe@example.com")
        ];
        
        $charge = $coinbaseHandler->createNewCharge($json);//get the charge object

        $this->redirect($charge->getHostedUrl());//it will redirect you to the coinbase crypto box to be paid in 15 minutes
    }

CALL WITH JSON STRING

   /**
    * @Route("/acceptcrypto/", name="acceptcrypto")
    */
    public function acceptDonation(CoinbaseHandler $coinbaseHandler){
        
        $json_string = "{\"name\":\"Cancer Donation Form\",\"description\":\"Donation to Children\",\"pricing_type\":\"fixed_price\",\"local_price\":{\"amount\":\"2.7\",\"currency\":\"USD\"},\"meta_data\":{\"id\":\"12345\",\"firstname\":\"Victor\",\"lastname\":\"Doe\",\"email\":\"vdoe@example.com\"}}";
        
        /**
        * @var Charge $charge
        */
        $charge = $coinbaseHandler->createNewCharge($json_string);//get the charge object

        $this->redirect($charge->getHostedUrl());//it will redirect you to the coinbase crypto box to be paid in 15 minutes
    }

CALL WITH CHARGE OBJECT

   /**
    * @Route("/acceptcrypto/", name="acceptcrypto")
    */
    public function acceptDonation(CoinbaseHandler $coinbaseHandler){
        
        /**
        * @var Charge $charge
        */
        $charge = new Charge();
        $charge->setName("Cancer Donation Form");
        $charge->setDescription("Donation to Children");
        $charge->setPricingType("fixed_price");
       
        $localPrice = new Money();
        $localPrice->setAmount(2.6);
        $localPrice->setCurrency("USD");
        $charge->setLocalPrice($localPrice);
       
       
        //Whatever object fields you wanna put
        $metadata = new Metadata();
        $metadata->id = "1234";
        $metadata->firstname = "Melisa";
        $metadata->lastname = "Doe";
        $metadata->email = "mdoe@example.com";
        $charge->setMetadata($metadata);
        
        /**
        * @var Charge $charge
        */
        $charge = $coinbaseHandler->createNewCharge($charge);//get the charge object

        $this->redirect($charge->getHostedUrl());//it will redirect you to the coinbase crypto box to be paid in 15 minutes
    }

Show a Charge

$code = "2G3GM4X9";
/**
* get a single charge
* @var Charge $charge
*/
$charge = $coinbaseHandler->showCharge($code);
$hosted_url = $charge->getHostedUrl();

List Charges

/**
* list charges
* @var Charges $charges
*/
$charges = $this->_coinbaseHandler->listCharges();

//iterate through the charges
foreach ($charges->getData() as $charge){
    print_r($charge);
}

Charge Object

Charge is one of your main object model that is re-usable once it is retrieved. It includes all other object models;

Addresses, Timeline, Pricing, Money etc..

It includes the raw json string as well in case you need to look up the fields manually.

$charge->getRawJson()

Here is an example of a returned Charge object that is already expired. No action taken in 15 minutes

Webhook

To retrieve a Webhook object from a json string, use the method below, just so simple!

/** @var Webhook $webhook */
$webhook = $this->_coinbaseHandler->parseWebhook($jsonString);

When Coinbase calls your webhook endpoint, follow the below example inside your controller

    /**
    * @Route("/webhooks/", name="webhooks")
    * @throws \Exception
    */
    public function webHook(Request $request, CoinbaseHandler $coinbaseHandler){

        if ($request->getMethod() != 'POST') {
            return new Response( 'Only post requests accepted!',  400);
        }

        $jsonString = $request->getContent();//get the json string from the request

        // This header contains the SHA256 HMAC signature of the raw request payload
        $cc_signagure = isset($_SERVER["HTTP_X_CC_WEBHOOK_SIGNATURE"]) ? $_SERVER["HTTP_X_CC_WEBHOOK_SIGNATURE"] : '';
        if(!$coinbaseHandler->validateWebhookSignature($cc_signagure, $request)){
                throw new \Exception("Request could not be validated");
        }
        
        /** @var Webhook $webhook */
        $webhook = $coinbaseHandler->parseWebhook($jsonString);
        //You have your webhook object. Do Something... save webhook data to database or email people or anything useful

        if($webhook->getEvent()->getType() == Event::TYPE_CHARGE_CREATED){
            //Do Something
        }

        return new Response('',Response::HTTP_OK, array('Content-Type' => 'text/html'));//make sure you respond with status 200 (OK) at the end
    }

Webhook Object

Here is an example of Webhook Object
