php

$data = json_decode(file_get_contents('php://input'), true);

$curl = curl_init();

curl_setopt_array($curl, array(
CURLOPT_URL => "https://api.example.com/v1/users",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_C"

I also just realized that the character limit is indeed in some cases very limited.
