Did access tokens get a new format?

I’m trying to query the API for information that is only available with authorization.

So for this, I have gotten a refresh token and then I exchange it to an access token at the URL (link removed)

That gives me an access token that is about 180 characters long. But, if I then try to use that access token on an API like (link removed) then I get an error “invalid token”.

I have tried that same query on API Explorer - EVE: Developers and there it works correctly. However I noticed that on that website, the access token is almost 1000 characters long. If I copy that access token into curl and run that query myself, the query also works correctly.

So my question is: Did Eve Online recently upgrade its token lengths? If yes, how can I request one of those higher length tokens that will be accepted by the API endpoints?

By the way, I also tried using the URL (link removed) to instead get the access token, but that one gives me an error “grant type is not supported” instead.

Sorry, I can’t put links here.

But the first one is supposed to point to hxxps oauth token?grant_type=refresh_token&refresh_token=(myrefreshtoken)

The second one is supposed to point to hxxps characters characterid orders

The third one is supposed to point to hxxps v2 oauth token?grant_type=refresh_token&refresh_token=(myrefreshtoken)
