What is a Headless CMS

A Headless CMS is a hot trend in web development. It provides a ready-to-go way to manage your data with a visual dashboard like traditional CMS (WordPress, Drupal) but allows you to pull the data via an API so you can use the frontend technologies of your choice. Headless CMS's are a powerful and popular combo with a Static Site Generator but can be used in most web applications.

To see a list of all Headless CMS solutions and Static Site Generators checkout the directories at JAMStack.org.

$.ajax

const guid = //get guid in the settings section under api keys

const apikey = // get apikey in the setting section under api keys

$.ajax({
 url: `https://api.aglty.io/${guid}/fetch/en-us/list/myblog`,
 headers: {
     accept: "application/json",
     APIKey: apikey
 }   
})
.then((response) => {
    console.log(response)

    //use the data to populate your webpage from here
})

fetch

const guid = //get guid in the settings section under api keys

const apikey = // get apikey in the setting section under api keys

fetch(`https://api.aglty.io/${guid}/fetch/en-us/list/myblog`,{
  headers: {
     accept: "application/json",
     APIKey: apikey
 }   
})
.then((response) => response.json())
.then((data) => {
    console.log(data)

    //use the data to populate your webpage from here
})

Axios

const guid = //get guid in the settings section under api keys

const apikey = // get apikey in the setting section under api keys

axios({
  url: `https://api.aglty.io/${guid}/fetch/en-us/list/myblog`,
  headers: {
     accept: "application/json",
     APIKey: apikey
 }   
})
.then((data) => {
    console.log(data)
    console.log(data.data) // <== This is the api data

    //use the data to populate your webpage from here
})
