Legacy Billing Reference for Confluent Cloud
This page documents legacy Confluent Cloud billing models and API response formats that applied to organizations created before their respective cutover dates. If your organization was created after the applicable date, this content doesn’t apply to you; see Billing Dimensions in Confluent Cloud or Retrieve Invoices and Costs in Confluent Cloud instead.

These changes are only applicable to Confluent Cloud organizations created on or after April 16, 2024. All organizations created before this date are not affected and continue to use their existing cluster pricing model and limits, described in the following tables.

Legacy Costs API response format
Costs API responses for Confluent Cloud organizations created before May 15, 2024 use a different response format than organizations created on or after that date. If your organization was created before May 15, 2024, the GET/billing/v1/costs request described in Retrieve costs for a range of dates returns a response in this format instead:
Response
Highlighted lines show the range of dates from your request and total costs.
