At present, during the weekly sync of Zendesk users into Canny, Canny can hit the rate limit for certain Zendesk API limits if there are a lot of users synced. This is especially prevalent for customers using a less costly tiered instance of Zendesk.
This results in emails being sent by Zendesk support and potentially impacts other applications using the API.
In future we could alter our integration to ensure adequate amounts of the rate limit are reserved for other applications.
