In order to gain access to your Spotify for Artists account and become a verified Spotify artist, you will need at least 1 album from Catapult that is live in Spotify. If you have just submitted your first album for distribution via Catapult, it can normally take up to a week or so before you can take advantage of Spotify for Artists (Assuming your album is live in Spotify).
If you need to get verified before your first album goes live, please let us know, and we can e-mail you your Spotify Artist URI so you can verify directly with Spotify manually.
