Capture order returning 404 HTTP error

[rodrigomsr]

Hello, I'm trying to create an order and capture the payment (I don't know if this is the correct way to do it). However, when I try to capture the order, I simply get a 404 error. I am doing this in the sandbox environment.

First, I create an order and use the approval link to pay. Then, when the payer accesses application_context.return_url I try to capture the order from the "token" GET parameter.

Code (PHP):

<?php
	$clientId = "xxxx";
	$secret = "xxxx";


	//Get Authorization Token
	$ch = curl_init();

	curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.paypal.com/v1/oauth2/token");
	curl_setopt($ch, CURLOPT_HEADER, false);
	curl_setopt($ch, CURLOPT_POST, true);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
	curl_setopt($ch, CURLOPT_USERPWD, $clientId.":".$secret);
	curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=client_credentials");

	$result = curl_exec($ch);
	$err = curl_error($ch);

	$access_token = FALSE;

	if($err)
	{
		echo "cURL Error #:" . $err;
	}
	else
	{
		$json = json_decode($result);
		// print_r($json->access_token);
		$access_token = $json->access_token;
		echo "<br>Access token success<br><br>";
	}

	curl_close($ch);


	


	//Capture order
	if(isset($_GET['token']))
	{
		$token = $_GET['token'];
		
		$ch = curl_init();
		
		curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.paypal.com/v2/checkout/orders/$token/capture");
		curl_setopt($ch, CURLOPT_HTTPHEADER,
			array(
				"Content-Type: application/json",
				"Authorization: Bearer $access_token",
				"Prefer: return=representation"
			)
		);
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
		
		$result = curl_exec($ch);
		$err = curl_error($ch);

		if($err)
		{
			echo "cURL Error #:" . $err;
		}
		else
		{
			$json = json_decode($result);
			print_r($json);
		}
		
		echo "<br><br><br>Order capture. HTTP: ".curl_getinfo($ch, CURLINFO_HTTP_CODE);
		
		curl_close($ch);
		exit();
	}






	//Create order
	$ch = curl_init();

	curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.paypal.com/v2/checkout/orders");
	curl_setopt($ch, CURLOPT_HTTPHEADER,
		array(
			"Content-Type: application/json",
			"Authorization: Bearer $access_token"
		)
	);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
	curl_setopt($ch, CURLOPT_POST, true);
	curl_setopt($ch, CURLOPT_POSTFIELDS, '

	$result = curl_exec($ch);
	$err = curl_error($ch);

	if($err)
	{
		echo "cURL Error #:" . $err;
	}
	else
	{

		print_r($json);
		echo "<br><br>Link: ".$json->links[1]->href;

	curl_close($ch);
