I’ve successfully setup OAUTH 2 with PKCE for zoominfo (please don’t judge). However, it seems the token refresh isn’t natively handled in the Credentials setup. As a result I have to manually click to reconnect every 24 hours. Not ideal.
I have developed a work-around with a flow + data table, but I’d obviously prefer to solve for this via a native credentials setup. Any tips would be greatly appreciated!
