Method Detail

getToken

public Token getToken()

Fetches an endpoint-specific dataplane token by exchanging a control plane token.

Specified by:

getToken in interface TokenSource

Returns:

A new Token containing the exchanged dataplane access token, its type, any accompanying refresh token, and its expiry time.

Throws:
