How can I get the source channel in LIFF APP ?

Question

Right now, I'm going the way to setup URL with query param which is channel identity
e.g. https://liff.line.me/LIFF_ID?channelId=CHANEL_ID

How can I get the source channel identity e.g. channel id, channel name by programmatically without passing query param as above ?

Hi Snorf,

You can get them by calling `liff.getDecodedIdToken()` after `liff.init()`.
The value of "aud" in response corresponds to the channel ID.
