ID Token
The ID Token is the payload of an LTI® 1.3 launch: a JWT, signed by the platform and verified by the tool against the platform's key set.
It carries the user's identifier and roles, the context the launch came from, the resource link that was clicked, and which LTI® services this launch may use.
LTIAAS verifies the token for you and exposes its contents in a developer-friendly shape — see retrieving the ID Token.
