Where can i find all files shared within a team in Microsoft Teams using the teams API?

Question

I would like to get the files within a team, just like they have them in the files tab.

I would like to replicate this on my own tab, just can't find anything where to start from.

I would also like to download the contents of the file(get the content in some way, base64, uint array...

You need to know team_id and channel_id

To list all teams in an organization you need to get a list of groups that have a resourceProvisioningOptions property that contains "Team".

Endpoint to list teams

GET https://graph.microsoft.com/v1.0/groups?$select=id,resourceProvisioningOptions

Endpoint to list team's channels (use id from previous query)

GET https://graph.microsoft.com/v1.0/teams/{team_id}/channels

Endpoint to get files and folders

GET https://graph.microsoft.com/v1.0/teams/{team_id}/channels/{channel_id}/filesFolder

The query above returns metadata about driveItem.

Use parentReference.driveId and id in the next API call to get folders and files

GET https://graph.microsoft.com/v1.0/drives/{drive_id}/items/{id}/children

It returns a collection of driveItems with unique id.

• If driveItem represents a file then file property is not null.

For each item that represents the file you can call

GET https://graph.microsoft.com/v1.0/drives/{drive_id}/items/{item_id}

to get more details about the file.

• If driveItem represents a folder then folder property is not null.

For each item that represents the folder you can call

GET https://graph.microsoft.com/v1.0/drives/{drive_id}/items/{item_id}
GET https://graph.microsoft.com/v1.0/drives/{drive_id}/items/{item_id}/children

to get more details about the folder or to get items inside the folder.

If you want to download the content then call

GET https://graph.microsoft.com/v1.0/drives/{drive_id}/items/{item_id}/content
