--header 'Authorization: Basic {base64 encoded string made of client_id:client_secret}'
--header 'Content-Type: application/x-www-form-urlencoded'
--data-urlencode 'grant_type=authorization_code'
--data-urlencode 'code={YOUR_CODE}'

It has been some time that you've asked dont know if you've already find out but this would help to others as well.

There is some informatical issues in pinterest doc.

  1. you need to pass client id and client secret to this curl request with other required parameters.

For e.g

        $vars = array(            
            "grant_type" => "authorization_code",
            "code" => <code_you_get_from_step_one>,
            "client_id" => env("PINTEREST_CLIENT_ID"),
            "client_secret" => env("PINTEREST_CLIENT_SECRET"),
            "redirect_uri" => 'http://localhost:8000/auth/pinterest/callback'
        );
        $headers = [
            'Authorization: Basic '.base64_encode("$client_id:$client_secret"),
            'Content-Type: application/x-www-form-urlencoded'
        ];

        $ch = curl_init();
        curl_setopt($ch,CURLOPT_URL,"https://api.pinterest.com/v5/oauth/token");
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS,http_build_query($vars));
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

        $result = curl_exec ($ch);
        curl_close ($ch);

        dd($result);

2)If you're attempting with like above curl request As CBroe has mentioned in here As Manual says about CURLOPT_POSTFIELDS "if value is an array, the Content-Type header will be set to multipart/form-data "

That appears to be colliding with the application/x-www-form-urlencoded you are trying to send here.

Pass the data as a URL-encoded string instead, using http_build_query.

       curl_setopt($ch, CURLOPT_POSTFIELDS,http_build_query($vars));

Hope this is going to be helpful for other developers who are trying to integrate pinterest oauth.
