Easy Tutorial on How to Implement Bing Index Now

How can I implement Bing Index now on my blogspot (blogger). I've been trying to figure out how the Verification of the host on the API key works and how to host your UTF-8 key file. I tried searching online if there's a comprehensive but easy-to-follow guide on how to use Index Now to Blogger but failed to find one. 

For WordPress, there is a plugin that is straightforward to Install. IndexNow Plugin for WordPress enables automated submission of URLs from WordPress sites to multiple search engines without the need to register and verify your site with them. Once installed, the plugin will automatically generate and host the API key on your site. It detects page creation/update/ deletion in WordPress and automatically submits the URLs in the background. This ensures that search engines will always have the latest updates about your site. This plugin submits URLs to a generic end point ‘https://api.indexnow.org/indexnow’ and these URLs are shared to all participating search engines.

Hopefully the Index Now plug-ins will also be available to "Blogger" soon. Bing provided a very brief tutorial on how to use Index Now as shown below but it seems not clear to me how to apply the code to have it work with Blogger.

Here are the steps provided by Bing Webmaster to implement the system:

For Word Press:

You just need to install the plugin and set up automatic submission of new pages in your WordPress site. It's that simple!

• Log in to WordPress admin panel for your WordPress site. Click on Plugins > Add New.
• Search for IndexNow Plugin and install.
• Once installed, click on Activate to enable plugin.
• Go to IndexNow admin page under Settings > IndexNow and click Let's Get Started!.

For CloudFlare:

Crawler Hints is free to use for all Cloudflare customers and promises to revolutionize web efficiency. If you’d like to see how Crawler Hints can benefit how your website is indexed by the worlds biggest search engines, please feel free to opt-into the service:

• Sign in to your Cloudflare Account.
• In the dashboard, navigate to the Cache tab.
• Click on the Configuration section.
• Locate the Crawler Hints sign up card and enable. It's that easy.

For Blogger: This one is more complicated than the first two options.

1. Verification of host on API key

You will need to host your UTF-8 key file at

https://www.example.com/4f5b47d686164c7d88d512d4bdf0b267.txt

with the key 4f5b47d686164c7d88d512d4bdf0b267 in the content of the text file.

2. Sending of URLs

https://www.bing.com/indexnow?url=http://www.example.com/product.html&key=4f5b47d686164c7d88d512d4bdf0b267

3. SUBMITTING SET OF URLS VIA AN HTTP REQUEST

To submit a set of URLs using an HTTP request, and issue your POST JSON request to the following URL:

Request

POST /IndexNow HTTP/1.1
Content-Type: application/json; charset=utf-8
Host: <searchengine>
{
  "host": "www.example.org",
  "key": "4f5b47d686164c7d88d512d4bdf0b267",
  "keyLocation": "https://www.example.org/4f5b47d686164c7d88d512d4bdf0b267.txt",
  "urlList": [
      "https://www.example.org/url1",
      "https://www.example.org/folder/url2",
      "https://www.example.org/url3"
      ]
}
