How to send a message to a channel of MS Team using Graph APÌ?

I have used below commands to generate token for grant_type client_credentials.

curl --location --request POST 'https://login.microsoftonline.com/{tenant_ID}/oauth2/v2.0/token' --header 'Content-Type: application/x-www-form-urlencoded'  --data-urlencode 'grant_type=client_credentials' --data-urlencode 'client_id={client_id}' --data-urlencode 'client_secret={client_secret}' --data-urlencode 'scope=https://graph.microsoft.com/.default'

Then using token generated i ran following curl command to get list of channels and it run successfully.

curl --location --request GET 'https://graph.microsoft.com/v1.0/teams/{team_ID}/channels/' \

In response it throws Unauthorized Error

            "client-request-id": "d2e6aaa7-2884-4e4d-bd71"
        }
    }
}

Just to get this working for testing purpose, i have given all permissions for delegated and application(About 442 permissions) with admin consent but still response throws "Unauthorized Error"

So can someone help out over here, where am i getting it wrong.

What is right procedure to send a message to channel of a MS team using MS-Graph-api or what else needs to be enable/done which i am forgetting over here, to get this working.

Only delegated permission will work in this scenario & not the application permissions. Make sure you have the following permissions - ChannelMessage.Send, Group.ReadWrite.All - as one of the permissions is required to call this API. Just to isolate the above issue, test the same Graph API call, with the above said permissions in Microsoft Graph explorer and see if you can able to send message to channel or not. Here's the doc - docs.microsoft.com/en-us/graph/api/… – Dev
I checked the above error log info, but it doesnt have any info for analysis. Still if you can repro the issue, then get us the latest requestid, timestamp for further analysis. – Dev
Yes these " ChannelMessage.Send, Group.ReadWrite.All " permissions are also enable/provided. Here's latest Error log ``` { "error": { "code": "Unauthorized", "message": "Unauthorized", "innerError": { "date": "2020-11-15T02:19:41", "request-id": "ecccba94-b8ce-40d5-b9ff-5fd399ffe4c5", "client-request-id": "ecccba94-b8ce-40d5-b9ff-5fd399ffe4c5" } } } ```. I got above response when run from terminal and from postman – devops-admin
When tried to same command from Graph-Explorer having following " ChannelMessage.Send, Group.ReadWrite.All " mention permissions for delegated . Strangely it throws below response { "error": { "code": "MethodNotAllowed", "message": "Method not allowed.", "innerError": { "date": "2020-11-15T02:38:17", "request-id": "4448eed4-881a-4fad-98e1-bacf23ebb178", "client-request-id": "f18c5ddd-140e-3624-0de8-9b5ffd928ab5" } } } with auto-generated token for sign-in user in Graph-Explor – devops-admin
When run same request from Graph-Explorer also including bearer token in header generated for grant_type client_credentials from postman, i got below response { "error": { "code": "InvalidAuthenticationToken", "message": "CompactToken parsing failed with error code: 80049217", "innerError": { "date": "2020-11-15T02:53:22", "request-id": "c664d16f-2754-4ee3-b355-eb0eba066bcf", "client-request-id": "e4707e65-3d05-f7c0-2b97-8dae57a4cb88" } } }. What else could i try to get desired results. – devops-admin

  • Based on that you used grant_type as authorization code to send messages to a channel successfully.

Use grant_type as authorization code for sending messages to a channel as grant_type client_credentials is not supported in delegated permission as pointed out on this link as well https://developer.microsoft.com/en-us/graph/blogs/30daysmsgraph-day-12-authentication-and-authorization-scenarios/

For others to move forward follow above link to get the authorization code and use it to generate bearer access token to send messages to a channel

Delegated permissions required to generate bearer access token: "openid profile User.Read email"

To Generate access-token

curl --location --request POST 'https://login.microsoftonline.com/<Tenant_ID>/oauth2/v2.0/token' --header 'Content-Type: application/x-www-form-urlencoded' --header 'Cookie: x-ms-gateway-slice=prod; stsservicecookie=ests; fpc=AiMjowz5Jo5EvQyTMhzOqaQ9npEsAQAAAOMFRtcOAAAAqSBP-gEAAABXBkbXDgAAAA' --data-urlencode 'client_id=<client_ID>' --data-urlencode 'client_secret=<client_secret>' --data-urlencode 'redirect_uri=http://localhost' --data-urlencode 'grant_type=authorization_code' --data-urlencode 'scope=openid profile offline_access User.Read' --data-urlencode 'code=0.AAAAIfhr6OrWEEWP-3xobGRX8hpZv2PH4fVJh6PLsdEHaztTAOY.AQABAAIAAAB2UyzwtQEKR7-rWbgdcBZIMB3WJhW2dvCBgjVNf-tzDc_9Yc7YnN1JrIZtaE8b0L4RylYkzJkGWZAcxeTrMDhhjrjCJDGMOjkLPf8Jd0lLX6C7tFOU-RRg1tNDds0kI1RDdRJRYBMVFOr_riKgCwAKWgKrAd18Tr-anqLt_iTn7TLmCIN1dsL4wVFJPkhOBS0yPaoz0B07CzHWX2dUxMKhVoe7DpPibRxa6cue4zpm0JNqRWfuENIBf5qtOdghIeTa4DvrIosjhEKswdIKD1bc4LQIt6-y7-fUn7pNgbJH1b2PfOu-rtrrBjCgra9MMcnWKT_rx7Rgi_VHxERmm06SubWNI_YmmAwaSqj8ni_qUFZNULr5IT0RPIdaFmnb7xduvwfaeBdho0cHGJoBR3omYsaHygEK-xraP9vD-Dm3NdqlVYuQYKB2O5uVuyTDA--7sN7Ay5gQHkz98xfOuT4aU18YQ1Ji1vE5KffCbsFoUwzHiLoz-QcdMs7BBHR0C13z1o_qjx8SYgWZhlOwzA4-r91ErOi-AoZYqgk6yBhP_w7K-3YNFcxkNaqi4LIg8rarP0bFeioJgW3Htmsd1Ogk0y5kUSUnu1o5-paac8J9p9gpxuxM_Bj3GJ8P-SkuPueNY16kQ_qlW-JuqtrRp0mtFyeNVpHDY2vCUbJRpCw85tX247A-iGYBlsE7_BEj2wqcbeIZwXLOoKSmwxP2I5i_69m07FOz3hmYcl39sAjq8SItfFWcMPW1fWTEzqJy9dGsYulGHEDtx2iMTJsf9X_SEUrnAO8bqNLbJFDVcTFoxFrqFB7VjrjWH-4ed8erdHiEJnGVVjuQ1a_aW7pLIdo0r5zvF4PA9cvVjAlFyLi0ybhWD1vKu-EeTDqyG4uO2NW45Jow5GDGVPYIr2fKNZWdzNzFgcMsqo5hCsobL9lvd7DQIsa4W2dZ9UJjMQZ5NGKdcnL6ks8ZX44_DBcTkRBkWIXSJqEIh0WxdHjvC-_hWBifJ4xArQ5aAl5TucxEv7wwpB-tGou2mG_XvyLxNnrbOt-ltyc5aZTRZ1J_iOO7wX8AkNXM4-MsSFESyPAGhgJlClZCEtOZZLKhe99vmTvpinWyS72T5E1yWOUSCopFr2X2e0g-Fi8q1pNdAk1tw91ZtGhPBXk8BJAzjUut1T8nHiG_OE4inmGaK7rGsy-uKtCQGuALjxgpi_kAtDfGhYyzxiPe7Itu1od31M83y6H7ZOC9XVkQrI9jrt_Jn3wTwqRjFuwWwpCxK2iAc6y3pskgAA'
