Which day are you talking about?

Although its going to be a case of re-read the instructions. Which details how to authenticate.

Clue: x-api-header and postman\_api\_key

If you are talking about day 15, you need to fork the “secret” environment from the workspace where you forked all of the individual days\collections.
