Getting a Flickr authentication token

[Roccobot]

I configured several sites already, some using oauth.
Anyway, I can't manage to do that with Flickr. I'm not a developer, but I can follow someone's suggestion if given.
After generating API token values and setting access-token and access-token-secret in the config file, I get
[flickr][error] AuthenticationError: Invalid auth token
The two tokens should be more than enough to access the account, but looks like it isn't (or there's something wrong).

If I try the command
gallery-dl oauth:flickr, I get

[oauth][info] Using default flickr API key (XXXXXXXXXXX-XXXXXXXXXX)
[oauth][info] Opening URL in Default:

https://www.flickr.com/services/oauth/authorize?oauth_token=XXXXXXXXXXX-XXXXXXXXXX&perms=read

Waiting for response. (Cancel with Ctrl+c)

Then the browser opens a Flickr page with this error message:

Anyone can help please?

The default flickr API key used by the latest release got disabled, see #4332.

You can either use the -dev version or a "nightly" build, which has a new built-in key (7da954f),
or you register your own application and use its key (#4332 (comment)).

Oooooh, now I get it! I created my own app, but I was using access-token and access-token-secret instead of api-key and api-secret. It is working now, thank you! ✌️
