MS Teams - 在“应用 + 用户”上下文（图形 API）中，此资源不支持丰富的通知

Question

I'm trying to set up rich notifications for a channel subscription like in the docs below.

New or changed messages in a specific Teams channel: /teams/{id}/channels/{id}/messages

I'm supplying the details to the subscription url like below with ROPC auth flow.

{
    "changeType": "created,updated",
    "notificationUrl": "https://f554-118-110-222-226.ngrok.io/api/teams/events",
    "resource": "teams/TEAM_ID/channels/CHANNEL_ID/messages",
    "expirationDateTime": "2021-10-20T02:55:53Z",
    "encryptionCertificate": "encryptionCertificate",
    "encryptionCertificateId": "encryptionCertificateId",
    "includeResourceData": true,
  }

I should have all permissions necessary to access this resource since I can create a subscription when includeResourceData is false . However, I'm getting the following error when includeResourceData is true and I supply an encryption cert.

Operation: Create; Exception: [Status Code: BadRequest; Reason: Rich notification are not supported for this resource in 'app + user' context. Please set includeResourceData field to false.]

I think it might be with how my auth and permissions are set up but I'm not entirely sure what this means. Any help is appreciated

Would Suggest you to please try to revalidate and setup all the below prerequisite if might you have missed while setup change notification for team's channel.

• you need to include "includeResourceData" set to "true" and provide certificate information as described here
• you need to get your application approved

Other way to subscribe notifications for channel messages dynamically(eg powerapp - current user can subscribe to all of his joinedTeams or selected teams and receives push notifications) Because Ms Flows and Logic apps only lets you setup one at a time.

Please follow this MS Document for Set up change notifications that include resource data while creating subscription.

Found the answer to my question in this block of the docs. Thanks to RahulKumarShaw-MT for linking the right version.

The error below means that since the app was using ROPC auth flow it falls under delegated permissions and is not supported by the API to send encrypted data.

Operation: Create; Exception: [Status Code: BadRequest; Reason: Rich notification are not supported for this resource in 'app + user' context. Please set includeResourceData field to false.]

I got around this by having to set up an additional auth token with app permissions set up specifically for this purpose.
