Paypal API with PHP and cURL
curl, paypal, php
Solution
Having a good trawl around I pieced together parts from developers with other problems. I successfully gained my access token using the following code:
<?php
$ch = curl_init();
$clientId = "myId";
$secret = "mySecret";
curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.paypal.com/v1/oauth2/token");
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 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);
if(empty($result))die("Error: No response.");
else
{
$json = json_decode($result);
print_r($json->access_token);
}
curl_close($ch);
?>
Problem
I'm attempting "the first call" as outlined by the Paypal API documentation. This is the example provided that I'm following: ``` curl https://api.sandbox.paypal.com/v1/oauth2/token \ -H "Accept: application/json" \ -H "Accept-Language: en_US" \ -u "EOJ2S-Z6OoN_le_KS1d75wsZ6y0SFdVsY9183IvxFyZp:EClusMEUk8e9ihI7ZdVLF5cZ6y0SFdVsY9183IvxFyZp" \ -d "grant_type=client_credentials" ``` I have constructed a curl instance in PHP with all the above headers apart from the last one. What does a `-d` flag convert to as a curl option in PHP? There is little explanation there as far as I can tell. I managed to deduce `-u` as `CURLOPT_USERPWD`.
