Hi Blue Button API Users,


We will be making some additional infrastructure changes that will require downtime for the API on our Production environment. 


Maintenance to the production environment

Blue Button API’s production environment (api.bluebutton.cms.gov) will be unavailable Thursday, May 28 from 3:30 PM ET to 4:30 PM ET. During this time, any requests to the production API will receive a site maintenance message. 


When the API is available again, we will send confirmation messages to the community. Reach out if you have questions to bluebuttonapi @ cms.hhs.gov.


Thank you,

-The Blue Button API Team
