Upgrade to Transport Layer Security Version
Effective Monday, March 5, 2018, the FINRA TRACE, ADF and ORF Web API reference data download files will no longer be accessible using the Transport Layer Security (TLS) 1.0 protocol. FINRA will disable TLS 1.0, and firms using that protocol will not be able to establish connectivity to FINRA’s secure web servers to download the files. To gain access to the FINRA API reference data downloads, firms must migrate to TLS versions 1.1 or 1.2 by March 5, 2018. If possible, firms should use the most current version, TLS 1.2.
FINRA will provide a notice regarding testing opportunities for the newer versions of TLS as the migration date approaches.
Questions regarding this notice should be sent to FINRA Product Management or call (866) 899-2107.
