Hummingbird supports API calls up to 2mb in size. The available 2mb should be able to support thousands of individual transactions. FinCEN imposes a limit on transaction CSV attachments of 1mb, and Hummingbird will handle anything above that limit.

If you have any questions or concerns, please reach out to the Hummingbird team ().
