How long does it take for the API credentials to activate?

I’ve just created an Alpaca account a couple of days ago submitted my ID, etc, but did not deposit any funds yet. My registration status is in “Pending Approval”. I’ve tried creating a set of API auth data and playing with some python/c++ examples. I currently get an error 401- access key verification failed : access key not found (Code = 40110000). Are there some additional steps that I need to get the authentication key working, or does it just take more time until it gets activated?

I am having the same issue.
