FinCEN supports third-party technology providers that can transmit regulatory filings on your behalf. FinCEN refers to these third parties as “transmitters” – Hummingbird is registered as a transmitter with FinCEN. Hummingbird has extensive logic, automation, and testing to ensure that we maintain a strong connection with the FinCEN servers. We automatically monitor the health of our connection with FinCEN’s servers, and have incorporated smart logic to reconnect, retry, and monitor filing transmissions when our services experience any issues with the connection to FinCEN. One of our primary objectives at Hummingbird is to ensure that SAR filings are transmitted accurately, on time, and are valid per FinCEN’s specifications. --- # Agent Instructions This documentation is published with GitBook.
