API users should use the following data-center-specific base URLs for the Bullhorn OAuth, REST, and SOAP APIs:

https://auth.bullhornstaffing.com
https://rest.bullhornstaffing.com
https://api.bullhornstaffing.com

U.S. West Coast Data Center

CLS30,CLS31,CLS32,CLS33,CLS34

CLS70
https://auth-ger.bullhornstaffing.com
https://rest-ger.bullhornstaffing.com
https://api-ger.bullhornstaffing.com

Sandbox Environments

BHNEXT
https://auth9.bullhornstaffing.com
https://rest9.bullhornstaffing.com
https://bhservice9.bullhornstaffing.com

CLS91
https://auth-west9.bullhornstaffing.com
https://rest-west9.bullhornstaffing.com
https://api-west9.bullhornstaffing.com

CLS2, CLS4, CLS21 etc. are Cluster IDs that are contained in a user’s browser URL (address bar) once they are logged in.

Example: https://cls21.bullhornstaffing.com/BullhornSTAFFING/MainFrame.jsp?#no-ba... indicates that the logged in user is on CLS21 (therefore the appropriate API URLs to use are for the UK Data Center)
As such Cluster IDs do not change for a customer, so identifying the correct cluster ID for all users for a given customer is a one time exercise.
