I am trying to activate the index.php file which is a function for Stripe Connect. However, when I press the button on my HTML page to activate the function, it results in Cannot POST /pages/index.php. Both the HTML and PHP files are in the same folder. What I am trying to do is automate this: https://stripe.com/docs/connect/express-accounts#token-request

HTML CODE

<form action="input.php" method="post">

  <input type="submit" class="bg-transparent text-grey-darkest font-bold uppercase tracking-wide py-3 px-6 border-2 border-grey-light hover:border-grey rounded-lg" value="Continue">

</form>

PHP CODE

    <?php

  define('CLIENT_ID', 'ca_xxxxxxx');

  define('API_KEY', 'sk_xxxxxxx');



  define('TOKEN_URI', 'https://connect.stripe.com/oauth/token');

  define('AUTHORIZE_URI', 'https://connect.stripe.com/oauth/authorize');



  if (isset($_GET['code'])) { // Redirect w/ code

    $code = $_GET['code'];



    $token_request_body = array(

      'client_secret' => API_KEY,

      'grant_type' => 'authorization_code',

      'client_id' => CLIENT_ID,

      'code' => $code,

    );



    $req = curl_init(TOKEN_URI);

    curl_setopt( $ch, CURLOPT_USERAGENT, '' );

    curl_setopt($req, CURLOPT_RETURNTRANSFER, true);

    curl_setopt($req, CURLOPT_POST, true);

    curl_setopt($req, CURLOPT_POSTFIELDS, http_build_query($token_request_body));



    // TODO: Additional error handling

    $respCode = curl_getinfo($req, CURLINFO_HTTP_CODE);

    $resp = json_decode(curl_exec($req), true);

    curl_close($req);



    echo $resp['access_token'];

  } else if (isset($_GET['error'])) { // Error

    echo $_GET['error_description'];

  } else { // Show OAuth link

    $authorize_request_body = array(

      'response_type' => 'code',

      'scope' => 'read_write',

      'client_id' => CLIENT_ID

    );



    $url = AUTHORIZE_URI . '?' . http_build_query($authorize_request_body);

    echo "<a href='$url'>Connect with Stripe</a>";

  }

?>
