Curl Options - paypal/PayPal-PHP-SDK GitHub Wiki

Curl is used as our transportation engine for sending Rest API calls. You can configure Curl options as follows:

Configurations

• http.<CURL_OPTION>
  • Replace <CURL_OPTION> with one of the Curl constants.
  • e.g. http.CURLOPT_CONNECTTIMEOUT = 30

As you can see, any curl constant that needs to be added, needs to be prefixed with http..

By default, there are many configurations set by default. By defining any configuration here would override the default.
