Example 4: Send a message with file attachment in it

Request

The following example shows a request.

Notes:

  • The file to attach must already be in SharePoint. To access the file properties, GET the driveItem for the file. The eTag of the driveItem has a GUID that is your attachment ID. The webDavUrl of the driveItem is your attachment contentURL. You can use the name of the driveItem as your attachment name. You can use /drives/{drive-id}/items/{item-id} to get a drive item resource. To get webDavUrl, you have to explicitly select it via $select=webDavUrl or $select=*,webDavUrl.
  • Microsoft Graph supports the OpenUrl card action. Bots are required for other card actions.

Request

The following example shows a request.

Note: The temporaryId in the hostedContents collection is a random ID but must be the same across the body and hostedContents elements. (Notice the temporaryId set to 1 and the reference in the body as ../hostedContents/1/$value.)

contentBytes must be set to binary string Base64-encoded bytes. You can convert an item to binary Base64-encoded bytes in C# by using Convert.ToBase64String(File.ReadAllBytes("image.png"));, for example. Microsoft .NET SDK users don't need to convert to Base64 encoded bytes as the SDK handles it for you.

Example 7: Send a card with inline images

Request

The following example shows a request.

Notes:

  • The temporaryId in the hostedContents collection is a random ID, but must be the same across the content (in attachments) and hostedContents elements. (Notice the temporaryId set to 1 and the reference in content as ../hostedContents/1/$value.).
  • The maximum possible size of hosted content is 4 MB.

contentBytes must be set to binary string Base64-encoded bytes. You can do it in C# by using Convert.ToBase64String(File.ReadAllBytes("image.png"));. Microsoft .NET SDK users don't need to convert to Base64 encoded bytes as the SDK handles it for you.
