Changes to the Bloomberg Per Security Web Service

On June 2, 2018, Bloomberg will no longer support TLS1.1 and will only support TLS1.2 connection for their products - Bloomberg CANS (Corporate Action Notification Service) Per Security, Data License.

Consequently the EDM's Data Porter plug-in: Bloomberg Per-Security Web Service Plug-in will not be able to connect to the Bloomberg endpoint for Plug-ins of EDM versions 10.5 and lower.

EDM version 11.0 and above uses the 4.6.1 .NET framework as noted in our Compatibility page in EDM Confluence.  The plug-in for these versions will be able to connect with TLS1.2 protocol as .NET 4.6 and later is compatible with TLS 1.2 by default.

The Markit EDM team is enhancing this plug-in to ensure successful connection to the TLS1.2 supported Bloomberg endpoint that takes effect on June 02, 2018 for EDM versions of 10.5 and below that use an older .NET framework version.

Additionally, the Markit EDM team is introducing a parameter to change the Bloomberg webservice URL for all EDM versions of the plug-in. The default webservice URL will be the true Bloomberg endpoint - https://dlws.bloomberg.com/dlps. This plug-in parameter can be changed so clients can test with Bloomberg's UAT environment (e.g. https://dlws-uat.bloomberg.com/dlps). This enhancement can be used for testing with Bloomberg's UAT environment should there be future changes from Bloomberg.

If you do not use the Markit Bloomberg Per-Security Web Service Plugin, no further action is needed.  However, if you do use the plugin then please contact the Markit EDM Support team as soon as possible confirming which version(s) of EDM are affected and we will provide you with the updated plugin
