Hello Activepieces Team,
We are developing an Apify integration for Activepieces and would like to implement OAuth2 authentication for a better user experience.
We have registered an OAuth2 application in Apify Console and have
Client ID & Client Secret and the whole OAuth2 configuration ready to be shared with you.
Looking forward to your advice on how to best proceed. 
Hello @Misa_Fialova , Welcome to the Activepieces community, and thank you for reaching out!
At the moment, the Apify piece supports API key–based authentication. We will add OAuth2 auth support for the piece.
To proceed, could you please share the reference documentation for OAuth2 implementation, including the required authorization URL, token URL, and the scopes needed for the integration to work? If you have any guides or examples related to the OAuth2 flow, that would be very helpful as well.
Once we review and test the setup, we can add the Client ID and Client Secret to our cloud configuration for a predefined app. You may share these credentials via DM.
Let us know if you have any questions.
Thanks,
Kishan
