Hi BachThieu,

If you have access to Connect or Infrastructure Cloud you can grab the IDs from the browser URL.

It always looks a bit like this
/manage-imodel/unified-viewer/4b66e502-100f-4197-97d9-5345397ae4f7f/a5657087cf901d0fc7290c8424r22a4c559ab943

first you have the iTwin Id (not shown here) than the iModel Id and after the forward slash the changeset Id.

A better method, especially when dealing with many iModels would be to use the APIs. Start with getting all iModels in an iTwin;
https://developer.bentley.com/apis/imodels-v2/operations/get-itwin-imodels/
This will provide all iModel Ids. Than use the iModel Id(s) to get your changesets. Latest is always the one with the one with the highest "displayName"
https://developer.bentley.com/apis/imodels-v2/operations/get-imodel-changesets/

You could use the APIs in combination with Postman or PowerBI to always have an up-to-date list of all your iModels and their changeset Ids.

Hope this helps
