Extra / undocumented fields

Litecord provides extra fields for some objects due to the implicit requirement on them by Discord clients. However, they're not documented.

Objects that aren't documented in the Discord API, such as relationships aren't documented here. Take a look at the discord-unofficial-docs page instead.

User object

field	type	description
premium	boolean	if the user has nitro
mobile	boolean?	if the user has a phone number registered
phone	string?	the user's phone number, hardcoded to null for litecord.

Author user object for messages from webhooks

It contains an extra discriminator, set to '0000'. This is Discord undocumented behavior.
