Some channels provide features that can't be implemented by using only message text and attachments. To implement channel-specific functionality, you can pass native metadata to a channel in the Activity object's channelData
property. For example, your bot can use the channelData
property to instruct Telegram to send a sticker or to instruct Office365 to send an email.
This article describes how to use a message activity's channelData
property to implement this channel-specific functionality:
Channel | Functionality |
---|---|
Send and receive an email that contains body, subject, and importance metadata |
Note
The value of an Activity
object's channelData
property is a JSON object.
The structure of the JSON object will vary according to the channel and the functionality being implemented, as described below.
To create an email message, set the Activity
object's channelData
property to a JSON object that contains these properties:
{
"type": "ActivityTypes.Message",
"locale": "en-Us",
"channelID": "email",
"fromName": { "id": "mybot@mydomain.com", "name": "My bot"},
"recipientName": { "id": "joe@otherdomain.com", "name": "Joe Doe"},
"conversation": { "id": "123123123123", "topic": "awesome chat" },
"channelData":
{
"htmlBody": "<html><body style = \"font-family: Calibri; font-size: 11pt;\" >This is more than awesome.</body></html>",
"importance": "high",
"ccRecipients": "Yasemin@adatum.com;Temel@adventure-works.com",
}
}
This snippet shows an example of the channelData
property for a custom email message.
"channelData":
{
"htmlBody": "<html><body style = \"font-family: Calibri; font-size: 11pt;\" >This is more than awesome.</body></html>",
"importance": "high",
"ccRecipients": "Yasemin@adatum.com;Temel@adventure-works.com"
}
