We work on MS Teams bots. Each bot notification contains aadObjectId in request body by which we identify the user.
Sample Bot Request
{"name":"composeExtension/query","type":"invoke","timestamp":"2021-04-28T06:41:18.718Z","localTimestamp":"2021-04-28T12:11:18.718+05:30","id":"f:c3c988ef-b14b-b996-b3ec-cee22dbeb5ca","channelId":"msteams","serviceUrl":"https://smba.trafficmanager.net/in/","from":{"id":"29:1FKDpJ_2YcIMpBd94h8BABBpkrv_RVSSeeJ3qh8U3djsypgk2lnJxbq_Sd4eUVFE2lHXBuUBMQ_se7QEvYzTbtQ","name":"Test Account","aadObjectId":"7812b15f-6462-44ef-a772-d9012c55bf1c"},"conversation":{"conversationType":"personal","tenantId":"4d4f9f3f-2553-430b-b86b-442be9306e29","id":"a:1W4nBEGebG_h5wTFEGuyFYXr0_vCYTvg3-lIZ9uKaPFiDZmtU5FIA2PH880C09mrtxbqEeIJ-sPQvwy0qfDhmTOPuEGRtkoT7NGS1eTBHBfjWXWFMRgOK5yzsNMlL6i0d"},"recipient":{"id":"28:97f33763-604f-89ae-40b3-719c55e66177","name":"Test Bot"},"entities":[{"locale":"en-GB","country":"GB","platform":"Web","timezone":"Asia/Calcutta","type":"clientInfo"}],"channelData":{"tenant":{"id":"4d4f9f3f-2553-430b-b86b-442be9306e29"},"source":{"name":"compose"}},"value":{"commandId":"Contacts","parameters":[{"name":"initialRun","value":"true"}],"queryOptions":{"skip":0,"count":25}},"locale":"en-GB","localTimezone":"Asia/Calcutta"}
During initial authentication we store the user id. We use OAuth2.0 and the below Microsoft Graph API to get the user id.
https://learn.microsoft.com/en-us/graph/api/user-get?view=graph-rest-1.0&tabs=http
We noticed that id returned in graph api and from bot framework is same for business(or Work) accounts.
However for personal accounts it is different
Sample Id's for reference
Work Account
From Graph API - id : 7812b15f-6462-44ef-a772-d9012c55bf1c
From Bot - aadObjectId : 7812b15f-6462-44ef-a772-d9012c55bf1c
Personal Account
From Graph API - id : 47268d7805746036
From Bot - aadObjectId : 6542b15f-7632-a772-44ef-d9012c55bf1c
So how to get the aadObjectId for personal users?
