Once you've reached your quota for a given period, new Document generations will be blocked.
You can still create Documents with a draft status but switching the status to pending through the API or clicking Generate in the dashboard will result in the Document generation failing.
If you need to extend your quota for a given period, or in general. Contact our team by email or through the chat. We will discuss the possibility of boosting your quota with an internal upgrad we call Boost Packs.
