Channel Specific Resource
Since the broadcast password is channel specific (eg. each channel has its own broadcast password) you will need to specify the channel id (as returned at the Account & Server Information request.)
To generate a new broadcast password for a channel make a POST request to the following URL:
https://hub.api.caster.fm/channel/{CHANNEL_ID}/change_password?token={PRIVATE_TOKEN}
If the request is successful an HTTP status code 200 will be returned along with the following JSON:
{ "success": true, "error": null }
The newly generated broadcast password will be returned within the next Account & Server Information request you’ll make.
