Data-center-specific API URLs

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

U.S. East Coast Data Center

CLS4,CLS5,CLS2,CLS20,CLS6,CLS7

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

U.S. West Coast Data Center

CLS30,CLS31,CLS32,CLS33,CLS34

https://rest-west.bullhornstaffing.com
https://api-west.bullhornstaffing.com

UK Data Center

CLS21,CLS22,CLS23

https://rest-emea.bullhornstaffing.com
https://api-emea.bullhornstaffing.com

CLS2, CLS5, 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.
