You can bulk request customers (including events, excluding your private notes and tags) by sending a GET request with the limit option, which is a number between 1-100 ( 100 customers are requested by default) and offset option, which allows requesting next portion, starting from a specific number. For example, starting from the 300th customer. This can come in handy if you need to regularly update customers from your third-party database/CRM.

For sorting you can use ‘orderBy’ parameter and specify to sort by email or the lastSeen date.
