Get channel list in Slack

Question

I'm using Incoming webhooks to send message to the channel. I decide the channel in JSON format.

var message = {
    "text" : "text",
    "channel" : "#general",
    "username" : "me"
};

How can I get the list of channels in Slack?

Answer 1

You would need to use the Web API. Incoming webhooks are insufficient for this.

(Specifically, you want channels.list.)
