load all channels for a team and also fetch the filesFolder

Question

It is possible to load all channels for a team and also fetch the filesFolder property for each channel in a single request?

https://graph.microsoft.com/v1.0/teams/<id>/channels?$expand=filesFolder

is returning:
The query specified in the URI is not valid. Query option 'Expand' is not allowed. To allow it, set the 'AllowedQueryOptions' property on EnableQueryAttribute or QueryValidationSettings

Answer 1

Hi @Marco Dissel

To list channels for a team, you can use the below endpoint-

GET /teams/{team-id}/channels  

As per the documentation, expand query parameter is not supported for all the relationships and resources.
You can use direct endpoint to get FilesFolder for a teams channel.

GET /teams/{id}/channels/{id}/filesFolder  

Please refer get FilesFolder to know more.

Hope it helps.

Thanks, but I need to minimize the number of requests for performance reasons. Not for each channel a separate request to fetch the filesFolder.
