// hook.io has a range of node modules available - see
// https://hook.io/modules.
// We use request (https://www.npmjs.com/package/request) for an easy way to
// make the HTTP request.

// The parameters passed in via the slash command POST request.
var params = hook.params;
// Check that the hook has been triggered from our slash command by
// matching the token against the one in our environment variables.

// Set up the options for the HTTP request.
var options = {
// Use the Webhook URL from the Slack Incoming Webhooks integration.
uri: hook.env.highfive_url,
method: 'POST',
// Slack expects a JSON payload with a "text" property.
json: {

// Request that Slack parse URLs, usernames, emoji, etc. in the
// incoming text.

}
};
// Make the POST request to the Slack incoming webhook.
request(options, function (error, response, body) {
// Pass error back to client if request endpoint can't be reached.
if (error) {
hook.res.end(error.message);
}
// Finally, send the response. This will be displayed to the user after
// they submit the slash command.
hook.res.end('High five success! Go to #highfives to see it :smile:');
});
} else {
// If the token didn't match, send a response anyway for debugging.
hook.res.end('Incorrect token.');
