Vendas Online via API com PayPal - #6 Criando a Fatura

Nesse tutorial vamos enviar os dados da nossa loja virtual para a API do PayPal para que seja criada a fatura da transação.

Transações pelo PayPal

controllers/ControllerInvoice.php

Esse controller enviará os dados para API gerando a fatura.

<?php
require_once ('../config/config.php');
require_once ('../class/ClassPayment.php');
$objPayment=new ClassPayment();
$data='{
  "intent": "sale",

    "payment_method": "paypal"
  },

$objPayment->invoice($data);

class/ClassPayment.php

Vamos criar um novo método na classe de pagamento e alguns ajustes no método curl e getToken:

//Curls
private function curls($action){
    $ch=curl_init();
    curl_setopt($ch,CURLOPT_URL,$this->url);
    if($action == 'token'){
        curl_setopt($ch,CURLOPT_HEADER,false);
    }else{
        curl_setopt($ch,CURLOPT_HTTPHEADER,array("Content-Type: application/json", "Authorization: Bearer ".$this->token->access_token.""));
    }
    curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);
    curl_setopt($ch,CURLOPT_POST,true);
    curl_setopt($ch,CURLOPT_POSTFIELDS,$this->post);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
    ($action == 'token')?curl_setopt($ch,CURLOPT_USERPWD,CLIENTID.':'.SECRETKEY):false;
    $data=curl_exec($ch);
    curl_close($ch);
    return json_decode($data);
}

//Get a access token
public function getToken()
{
    $this->url=URL.'v1/oauth2/token';
    $this->post="grant_type=client_credentials";
    $this->token=$this->curls('token');
}

//Invoice
public function invoice($data)
{
    $this->getToken();
    $this->url=URL.'v1/payments/payment';
    $this->post=$data;
    var_dump($this->curls('invoice'));
}

Por hoje é só! Sucesso nos códigos e na vida!
