Hi,

Answer 1

The value for resource in your request body is improperly formatted. The site Id is not just a GUID, it's a value made up of the tenant host name, the site collection GUID, and the site GUID. It should look something like this:

contoso.sharepoint.com,130df549-fe92-4160-a4d6-151b48335fa2,427124d7-af02-4009-97f6-5b7c1d17873f

You can get the site id by making a request using the tenant host name and the server relative URL. It would look something like this:

https://graph.microsoft.com/v1.0/sites/contoso.sharepoint.com:/sites/Demo

Once you have the site Id, you can update the value of resource look something like this:

/sites/contoso.sharepoint.com,130df549-fe92-4160-a4d6-151b48335fa2,427124d7-af02-4009-97f6-5b7c1d17873f/lists/b158ba42-e98a-4813-8cc9-100c58227801

Hi @Chintan Upadhayay
You could try to use SharePoint rest api to create subscription

POST /_api/web/lists('5C77031A-9621-4DFC-BB5D-57803A94E91D')/subscriptions  

Here is the document for details
