@protocol SCCameraKitAccessTokenProvider <NSObject>

protocol AccessTokenProvider : NSObjectProtocol

Describes an interface to provide an access token (ie. from LoginKit) required by some features like connected lenses, push to device, etc.

  • If the user is already authenticated, fetch a valid/non-expired access token to be used by some features like connected lenses, push to device, etc. Returns an access token task if the fetch token task is cancellable or nil if the task is not cancellable.
