Bulk track events

Events are created asynchronously and <b>processed separately from single event (non-bulk) endpoint</b>. To make sure events are tracked in order, send them all to the same endpoint (either bulk or non-bulk). <br/><br/>There is a soft limit (default is 8,000) on the number of unique fields a custom event can have. For events of the same name, identically named data fields must be of the same type.<br/><br/>Learn about <a href="https://support.iterable.com/hc/articles/29156459027348">identifying users by <code>userId</code> and <code>email</code></a>.<br/><br/><b>Rate limit</b>: 10 requests/second, per project.
