1. 1.
    Have a Kontent CMS setup.
  2. 2.
    Add custom element
Content model (left hand side) > Create new > Custom element (right hand side). You will then have the below view.
"token": "your_token",
"secTemplate": "your_security_template",
"dir": "your_base_directory"
note: "dir" element is optional, by default will go to the root folder of your library. Do not add "/" at the start & end of the directory string.
  1. 3.
    Create new content with this Custom Element
Content & asset (left hand side) > Create new > Chose type: FMAW. Chose and add some images, publish. You will then have the below view.
The images below are the images added in from FMAW into a Kontent content-item. When they are added, they will have Filerobot-URLs (instead of their Strapi CMS URLs).


Go to Settings > API Keys. For this, you will definitely need your Project ID. You may also need your API Key (depends on what you want to do, but for simple things Project ID is enough).
Write a client app that utilizes the Delivery API
Recall that Kontent have 3 set of APIs that you can interact with
Delivery APIs in plain HTTPS form can be downloaded from and imported into POSTMAN
For the 3 content items that comes out of the box, Kontent already have an example client app, which we can imitate.
After writing and hosting your client app, go to Settings > Preview URLs and define your Preview URL formats.
See how Kontent defined their preview URLS for their example app
Codename, URLSlug & ItemId are obtained as follows:
Once you done all the above, you can preview by clicking Preview
