How to Transform this cURL code to PHP (PayPal API) - php

Question

I have the following code
curl -v https://api.sandbox.paypal.com/v1/payments/payment \
-H 'Content-Type:application/json' \
-H 'Authorization:Bearer EEwJ6tF9x5WCIZDYzyZGaz6Khbw7raYRIBV_WxVvgmsG' \
-d '{
"intent":"sale",
"redirect_urls":{
"return_url":"http://example.com/your_redirect_url/",
"cancel_url":"http://example.com/your_cancel_url/"
},
"payer":{
"payment_method":"paypal"
},
"transactions":[
{
"amount":{
"total":"7.47",
"currency":"USD"
}
}
]
}'
I have been trying to convert it, but I don't know which parameters to use.
How can I convert it to PHP?

Answer 1

Looks like you'd need to do this. Note that because you're passing a JSON header, PayPal is (likely) requiring the body data to be sent as JSON, rather than form/value pairs. If you're passing a complex set of data, you may find it easier to define $data as an array, and use json_encode($data) to transform it for the CURLOPT_POSTFIELDS property.
$header = array();
$header[] = 'Content-type: application/json';
$header[] = 'Authorization: Bearer EEwJ6tF9x5WCIZDYzyZGaz6Khbw7raYRIBV_WxVvgmsG';
$url = 'https://api.sandbox.paypal.com/v1/payments/payment';
$data ='{
"intent":"sale",
"redirect_urls":{
"return_url":"http://example.com/your_redirect_url/",
"cancel_url":"http://example.com/your_cancel_url/"
},
"payer":{
"payment_method":"paypal"
},
"transactions":[
{
"amount":{
"total":"7.47",
"currency":"USD"
}
}
]
}';
//open connection
$ch = curl_init();
//set connection properties
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER,$header);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
//execute post
$result = curl_exec($ch);
//close connection
curl_close($ch);

You can use json_decode to do the leg work for you.
Simply feed it the string that cURL passes back to you and it will in turn convert your JSON into a php usable array.
