The Azure AAS url link be like below, which will be using in the Next step in ADF Pipeline > Web activity.
https://<region>.asazure.windows.net/servers/<AAS ServerName>/models/<AAS ModelName>/refreshes

Eg: Azure AS Server Name:
asazure:/<region>.asazure.windows.net/<AAS ServerName>
asazure:/centralus.asazure.windows.net/AAStestService

Eg: Azure AS URL/Link to Refresh:

Next choose the Web activity from the Pipeline > Activities > Web.
Next go to the Web > Settings > URL and pass the URL like below of your AAS Model to refresh.

https://<region>.asazure.windows.net/servers/<AAS ServerName>/models/<AAS ModelName>/refreshes

Next in the body use the below Json Script to Process the AAS Model:

To full process the entire Model:

{
"Type": "Full",
"CommitMode": "transactional",
"MaxParallelism": 2,
"RetryCount": 2,
"Objects": []
}

To full process specific Table/Partition of the Model:

{
"Type": "Full",
"CommitMode": "transactional",
"MaxParallelism": 2,
"RetryCount": 2,

"Objects": [

Next choose the Authentication as "Managed Identity".

Next in the Resource, you can pass the below link:
https://*.asazure.windows.net

Finally Save and Excecute(Debug) to run the Web task and process the Cube.

Notes:
We can use the "GET" method and run the Pipeline to see the Model refresh status.

6) Finally, Add a Trigger and Schedule the ADF Pipeline for Automatically Refresh AAS Model:
Go to ADF > Pipeline > Triggers , then add a Trigger to run the Pipeline at a specified Schedule(Every Minute/Hour/Week/Month).

Finally Save and Publish the ADF Service.
