# Bullhorn

> Resources, examples, configuration and evidence for Bullhorn.

Use the `@bijection/connectors/bullhorn` entrypoint to declare Bullhorn resources.

## Availability

This page describes the pinned source package. Published availability is unestablished for this artifact. [Source build and package availability](https://docs.bijection.com/client/sdk-distribution.md).

## Resources and modes

| Resource | Mode | Description |
| - | - | - |
| Entities | `pull` | dateLastModified keyset with a carried position, isDeleted withdrawal |
| Event subscription | `consume` | Destructive event reads recovered by requestId |

Declare a resource in application code, then bind deployment-specific settings and credentials. See [typed resources](https://docs.bijection.com/integrations/resources.md), [connections](https://docs.bijection.com/integrations/connections.md) and [source inspection](https://docs.bijection.com/integrations/cli.md).

## Entities

### pull: dateLastModified keyset with a carried position, isDeleted withdrawal

The following example matches configuration `standard`.

```ts theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
import { bullhorn } from "@bijection/connectors/bullhorn";

export const appointments = bullhorn.records.pull({
  entity: "Appointment",
  fields: ["subject", "dateBegin"],
});
```

> **Inferred record types**
>
> ```ts theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
> Resource without an operational record table
> ```

#### Configuration: standard

Case: `bullhorn/records/pull/standard`.

Connection and resource configuration are declared by this exact case.

Credential kind: `bullhorn`. Keep credential material in the private credential inventory.

| Setting | Type | Required | Owner |
| - | - | - | - |
| `restUrl` | string | Yes | Shared connection |

Hosted qualification: **unestablished for this catalog configuration**. Installed connections report their own identity, authority and current status.

## Event subscription

### consume: Destructive event reads recovered by requestId

The following example matches configuration `standard`.

```ts theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
import { bullhorn } from "@bijection/connectors/bullhorn";
export const events = bullhorn.events.consume();
```

> **Inferred record types**
>
> ```ts theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
> Resource without an operational record table
> ```

#### Configuration: standard

Case: `bullhorn/events/consume/standard`.

Connection and resource configuration are declared by this exact case.

Credential kind: `bullhorn`. Keep credential material in the private credential inventory.

## Provider guidance

Compiled declaration examples and configuration details are published in the [connector reference](https://docs.bijection.com/integrations/connectors/index).

Setup `restUrl` is the corporation's REST URL, which the `login` answer names.
The credential is a managed `oauth_refresh` envelope whose token protocol logs
each refreshed access token in (`POST /rest-services/login?version=2.0
&access_token=`) and presents the answered `BhRestToken` in the `BhRestToken`
header. The host refuses a login answer whose `restUrl` is not the connection's
base URL, and on a rejected session renews once. Bullhorn's token endpoint takes
its fields in the query, and its refresh tokens rotate on every use:

```json theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
{
  "kind": "oauth_refresh",
  "protocol": {
    "body": "query",
    "bearer_header": "bhresttoken",
    "session_login": {
      "endpoint": "https://rest-<swimlane>.bullhornstaffing.com/rest-services/login?version=2.0",
      "token": { "kind": "field", "name": "BhRestToken" },
      "resource_url_field": "restUrl",
      "lifetime_seconds": 600,
      "access_token_parameter": "access_token"
    }
  },
  "token_endpoint": "https://auth-<swimlane>.bullhornstaffing.com/oauth/token",
  "client_id": "…",
  "client_secret": "…",
  "refresh_token": "…",
  "refresh_context": { "kind": "authorization_code", "redirect_uri": "<the original redirect>" },
  "allowed_resource_origins": ["https://rest<n>.bullhornstaffing.com"]
}
```

Bullhorn states no session lifetime; `lifetime_seconds` is how long the host
reuses one session, and Bullhorn limits login rates, so it should not be short.

`records.pull` reads `query/<Entity>` with `where=dateLastModified>=<millis>`
ordered by `dateLastModified`. `dateLastModified` is an epoch-millisecond JSON
integer: it is the record version (its decimal text), and each page resumes from
the largest stamp the previous page returned, which the host derives. Boundary
rows are re-read and deduplicate; more rows in one millisecond than a page holds
fail the pass. A finished pass carries the largest stamp and the next starts five
minutes before it. `isDeleted: true` withdraws a record, so the entity must have
`isDeleted`. Search entities (`Candidate`, `ClientContact`, `ClientCorporation`,
`JobOrder`, `Lead`, `Note`, `Opportunity`, `Placement`, `Task`) are refused:
`query` does not serve them and `search`'s date-range syntax is not documented.
No account identity and no write (updates document no precondition).

`events.consume` reads one event subscription the operator created (`PUT
event/subscription/&#123;id&#125;`; setup `subscriptionId`), each event a record keyed by
its `eventId` with its entity, event type, timestamp, updated properties and the
acting person. A read purges what it returns, and only a re-read by `requestId`
returns a batch again, so every page first asks `lastRequestId`: a batch issued
after the last committed one was read and lost before its page committed, and is
re-read by id; only when the two agree is a new batch consumed (100 events at
most). The committed `requestId` is carried from pass to pass, so a crash between
Bullhorn's answer and the commit loses nothing within Bullhorn's re-read retention,
which Bullhorn does not state. A `lastRequestId` behind the committed one means the
subscription was recreated, and the pass fails. Two readers of one subscription
consume each other's events. What Bullhorn answers for an empty queue is not
documented; a non-JSON answer fails the pass. Events refresh no entity record.
Nothing here has run against Bullhorn.
