Create a [Google APIs project client ID](https://code.google.com/apis/console#:access).\n\n | **Warning:** Do not use the client ID that you use for your production Glassware for the Playground. Always create a new client ID for testing, which can reside in the same Google APIs project.\n2. Add `https://mirror-api-playground.appspot.com` to the list of authorized\n `JavaScript` origins for the client ID\n\n3. Copy your client ID to the Playground and start interacting with\n your timeline."]]
