    Returns an authorization token

    Used to log in to the B2 API. Returns an authorization token that can be used for subsequent API calls, and a URL that should be used as the base URL for subsequent API calls.

    You can use either the master application key or a normal application key.

    NOTE the account ID can be used in place of the master application key ID.

    You'll find the master application key in the Backblaze web UI. When using the master application key, use your "master application key ID" and the "application key" you got from the site.


    Master Application Key This is the first key you have access to, it is available in the Backblaze web UI. This key has all capabilities, access to all buckets, and has no file prefix restrictions or expiration.

    Application Key(s) [non-master] These are other keys created by you and can be limited to a bucket, with a specific file prefix and can expire.


    Normal application keys come from the b2_create_key call. When using one of them, the "application key ID" and "application key" are the ones returned when you created the key.
