Drupal commerce posting to API via curl

Im using a the commerce module and i have a few fields from the checkout of an order i want to post to another external system. Currently i use: $ curl -u user:"password" -X POST http://8.8.8.8/api/v1/[login to view URL] -d method="addUser" -d first_name="Joshua" -d last_name="Iixuna" -d address="XXX Gladiola Street" etc. So currently i go to each checkout and copy and paste the info into my pre defined curl script and then run it.. and it works... But i just want to make it an automatic process collecting the info from the order and passing it on. I understand this can be done with drupal_http_request($url, array $options = array()) ... My challenge is that im not soo got at the coding part.... Anyone with experience with Drupal http request? [login to view URL] Or perhaps if once can help set up a run that will do that...Im out of ideas.
