@vrfaria what endpoint are you hitting? Are you using oauth1 or oauth2? I assume your server is version 2022.1?
Moreover, the API Documentation webpage seems to be dawn. Is it possible for it to be the cause?
I've already checked my API key and the workflow key, they are still valid. I see no reason for it to start cracking other than a new version's issue since it has been working perfectly for the last three months
@vrfaria if your server is on 2022.1, oauth1 was deprecated and is no longer available. You would need to switch to oauth2 (https://help.alteryx.com/20221/server/oauth1-oauth2-instructions). As for accessing the documentation, The api documentation is pointed to localhost by default, and a alteryx server admin has to change the URL in the alteryx system settings.
