Setup of yotpo API in website admin of e-com website

The yotpo api requires authentication through a json request and then needs to be set to send the order details to yotpo when the customers order status is changed to "shipped" order status id = 3 The yotpo documentation can be found here: [login to view URL] This is for a "general" platform as we are using oscommerce currently. I have already created the authentication file and it works and returns the user token. When needs to be done is: set the oscommerce admin/[login to view URL] to "create an order" using the yotpo api (see section [login to view URL]) when the order status is changed to shipped. The order details (email, productid, customer name etc all need to be sent to yotpo through this same api call I attached the [login to view URL] page. line 76 I believe is where the order must be created. I also have the [login to view URL] file I created that looks like this: <?php $yotpo_keys = array( "client_id"=> "myid", "client_secret"=> "mysecret", "grant_type"=> "client_credentials" ); $ch = curl_init( "[login to view URL]" ); # Setup request to send json via POST. $payload = json_encode( $yotpo_keys ); curl_setopt( $ch, CURLOPT_POSTFIELDS, $payload ); curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json')); # Return response instead of printing. curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true ); # Send request. $result = curl_exec($ch); curl_close($ch); # Print response. $yotpo_token_array = json_decode($result, true); echo $yotpo_token_array[access_token]; ?> The access token is echo'd at the end of that file but needs to be brought into the request on the orders page.
