Hi there,
We (CustomerSure) have existing stores connected (via the ruby shopify_api gem) to our app which currently uses legacy auth. I am about to start the update to OAuth2 and get our shopify_api gem version bumped to 3.0.3.
Our main concern is keeping the existing stores connected after we perform the one way update to OAuth2. Hopefully the customers will not need to re-authenticate after the new codebase goes live, is this possible? Is there anything special we should be looking to do?
Many thanks,
Luke Brown.
