Get Cortana's channel data

Cortana and skills use the message's channelData property to pass Cortana-specific data. The channelData property is an object that contains the following properties:

Name Type Description
skillId string An ID that uniquely identifies the skill. This is regenerated for each deployment. For example, the ID may be 123 when the skill is deployed to self, and 656 when it's deployed to group.
skillProductId string An ID that uniquely identifies the skill.
isDebug Boolean Specifies whether Cortana is in debug mode. If true, debugging is enabled and messages are written to her canvas. For more information, see Enable debugging in Cortana.

Here's an example of the channelData object that Cortana sends.

  "skillId": "3253-fsafa-32522-afa3a",
  "skillProductId": "A7CDE-5DD1-42EA-A436-49D7365",
  "isDebug": true

In addition to using channelData to receive Cortana-specific information, you can include it in your skill's outgoing message to have Cortana launch an app or a website. For information, see Launching apps or websites from a Cortana skill.
