With the new Version 2.0 Data Streamer, the default behavior of the REST API integration has changed. In Version 1.0 two options REST API and REST API Bulk were available. With the migration to Version 2.0, the only the REST API Bulk integration is available. Newly created streams will no longer receive single HTTP POST requests for each individual record. Event and Usage records will be provided as a list of JSON objects. The default maximum amount of records in a single HTTP POST request is 3000 items.
