Hey @Appifiny ,
Thanks for response. Yes, I've actually updated event subscription version long time ago. It looks like the issue is not related to webhooks, but cursor based pagination. The weird part is that, we've implemented cursor pagination for a very long time ago. Since then we've never got any warning or issue. Suddenly it started to display red api health alert in partner dashboard.
We updated all our pagination code a few months back but we still continued to get warnings about the pagination in the health dashboard.
I know webhooks are not related to the pagination but as soon as we updated the API version to July 2020 in the event subscription setting, it fixed the warnings in the health dashboard the next day.
Also make sure your API calls are using the same version.
