John I eventually sorted this out. Solution involved: POST params needed to be json_encoded $params=json_encode(array( name = value )); Thanks to http://www.lornajane.net/posts/2011/posting-json-data-with-php-curl curl_setopt($ch, CURLOPT_CUSTOMREQUEST, POST); curl_setopt($ch, CURLOPT_POSTFIELDS, $post); Also, included headers as array and set application type as json: curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Content-Type: application/json', 'Content-Length: ' . strlen($post)) ); Set encoding to auto-detect: curl_setopt( $ch, CURLOPT_ENCODING, ); John -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] PHP CURL JSON POST Firebug
