The document summarizes recent evolutions to the Bullhorn REST API including enhancements to authentication, new entities, and SDKs to simplify front-end development. Key points include: - Authentication was simplified to directly retrieve an auth code from customizations or get the access token in two steps. - New entities like billable charges and invoice statements were added to support the Bullhorn One time tracking and invoicing workflows. - Entities can now have effective dates to support updating values over time. - The Taurus JavaScript SDK and Bullhorn types library make querying data and building the front-end easier through features like auto-caching and reactive programming. - Custom cards can be built

4. Auth Process

5. Auth Process
Step 1 - get the authentication code
URL: https://auth.bullhornstaffing.com/oauth/authorize
Method:Post
Payload:
client_id={client_id}
response_type=code
state={recommended state value}
Response: code
username={username}
password={password}
action=Login

6. Auth Process
Step 2 - get the access_token
URL: https://auth.bullhornstaffing.com/oauth/token
Method:Post
Payload:
client_id={client_id}
client_secret={client_secret}
Response: access_token
grant_type={authorization_code}
code={auth_code}

7. Auth Process
Step 3 - get the rest token
URL: https://rest.bullhornstaffing.com/rest-
services/login
&Method:Post
Payload:
version=*
access_token={xxxxxxxx}
Response:
BhRestToken, restUrl

8. Easier Auth with Customizations
• Skip step 1, get authCode directly from the
customization
– Custom Card
– Custom Tab
– Custom Action
• Get access_token followed by BhRestToken

11. Meta
• What entities are available?
– /meta
• What properties do those entities have?
– /meta/Candidate?field=*

12. Entity
• GET - Read
• PUT - Create
• POST - Update
• DELETE - Delete

13. Search and Query
• /search/Candidate
• /query/Tearsheet

14. Bullhorn One Enhancements

15. Time Entry Workflow

19. New Entities
• Billable Charge
• Payable Charge
• Invoice Statement
• Invoice Statement Line Item

20. Effective Dated Entities
• Location
• Invoice Term
• Billing Profile

21. Using EDEs
• Add new root
• Add new version
• Update version
• GET with effectiveOn date

22. Taurus - javascript REST sdk for the
front end

23. Taurus Capabilities
• Auto caching
• Reactive API
• Easy query construction syntax
• Front-end Only

25. Retrieve Meta

26. Retrieving List Data

27. Filter Query Syntax
billingClientContact.name = ‘First Last’
jobOrder.clientContact.name = ‘First
Last’

28. Range Queries
For Search endpoint: currency: [120 TO
10000]
For query endpoint: currency > 120 AND
currency < 10000

29. • Deals with event streams
• A sequence of events that happen over
time
• Whenever an event occurs, we react to it
by doing something.
Reactive Programming

30. RXJS & Observables
• An observer subscribes to an Observable.
• Observer reacts to whatever item or
sequence of items the Observable emits.
• Concurrent operations - non blocking

isPublic?: boolean;
messageText?: Strings;
name?: Strings;
owner?: CorporateUser;

}
