Is there a limit on the size of API calls?

To ensure the safe and reliable operation of the Hummingbird platform, we enforce limits on the size of API payloads.

• Standard API Payloads:

  The API supports payloads up to 2 MB in size. This limit is designed to accommodate thousands of individual transactions efficiently.

• Alert Uploads API:

  This API is specifically designed to support larger datasets up to 10 MB in size and more detailed Alert requests.

A note on FINCEN - FinCEN imposes a size limit of 1 MB for transaction CSV attachments. Hummingbird will handle anything above that limit on-platform.

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