See this log from a client that is requesting a token request from an authUrl and then submitting that token request to Ably.

Instanced with an authUrl:

Note that no TTL is specified at this point which is completely valid. clientId and ttl are optional

Then when the token request body is sent to Ably, it has a TTL attribute invalidating the Mac:
