REST POST JSON using Gzip Content Encoding

See more REST Examples

Demonstrates how to send a JSON POST using the gzip Content-Encoding. Zig

const std = @import("std");

    // This requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // Use the online tool at https://tools.chilkat.io/Default.cshtml
    // to generate the JSON code that creates this JSON:

    // {
    //     "lists": [

    //     "email_addresses": [
    //         {
