I wrote an article here “How to disable/enable HTTP/2, Azure App Service” that showed how to change an Azure App Service setting Resource Explorer. You can also do this from Postman, which I wrote about here “Using Postman to call Azure REST APIs” .
The most challenging aspect of doing this is getting the Bearer token which is required so the request you are making from Postman is authenticated. In the article I already mentioned “Using Postman to call Azure REST APIs”, I show you how to get this token using Fiddler, you can also get it from an F12 Network trace log as well, Figure 1.

Then to get the Bearer token, I enter the following command and it is now in my clipboard, Figure 3.
armclient token <subscriptionId>

Yes, ok, I got “There is no login token. Please login to acquire a token”, so I logged in, using "ARMCLIENT LOGIN" and then re-executed the token request…Figure 4.

Now, to change, for example the “http20Enabled” attribute, first try a GET with the required headers, Figure 5. I used a URL similar to this:
https: //management.azure.com/subscriptions/<subscriptionId>/resourceGroups/ <resourceGroup>/providers/Microsoft.Web/sites/<appName>/config/ web?api-version=2016-08-01
I executed a GET request to make sure the request was working, Figure 5.

Then, to update the Azure App Service attribute, do the following:
- Use the same URL as you did with the GET method
- Select the PUT verb
- Copy the contents from the Body of the GET response
- Paste the Body into the PUT request
- Add the Authentication header
- Update the attribute you want to modify
- Press Send
Should look something similar to Figure 6.

Once successful, run the GET request again to retrieve the attributes and confirm the modification was performed.
