API little problem

[sevastian25]

So i have this API and i got a new file in my directory for it called "mylittleapi.php"

<?php

$curl = curl_init();

$coupon_code = '****-6dcf-****-4d05-bd68-****-****-****';

$data = json_encode(array(
	'coupon_code' => $coupon_code,
	'receiver_id64' => '76561************'
));

curl_setopt_array($curl, array(
  CURLOPT_URL => "https://theirwebsite.com/api/v1/money/coupon/redeem",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => $data,
  CURLOPT_HTTPHEADER => array(
    "authorization: Basic *******************************************************************=",
    "cache-control: no-cache",
    "content-type: application/json",
    "postman-token: ********-****-****-****-************"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

when i access it through www.mywebsite.com/mylittleapi.php it does execute but what i want to do is set the coupon_code as a variable which users can just enter their own coupons and set the Textbox and submit button in another page ex: "www.mywebsite.com/redeem"

 

I just need to make the variable for the coupon_code, link it to my textbox and button in the other page. Can somebody help me out please ? i really need this to be done.

Needs a little work, but the following should get you going in the right direction.

 

CLIENT SIDE:

<a href="?coupon_code=****-6dcf-****-4d05-bd68-****-****-****>click me</a>

SERVER SIDE:

$coupon_code=$_GET['coupon_code'];
