BambooHR (platform)

BambooHR is a mid-market HRIS with a built-in Hiring (applicant tracking) module and an open REST API centred on the Employee record: stock and tenant-defined custom fields, tabular history (job information, employment status, compensation), time off, custom reports and permissioned webhooks on employee field changes. Custom employee fields are created by an administrator in Settings and appear in the API through the fields metadata endpoint, addressed by numeric id, so they are written and read like stock fields. composerID publishes the approved permanent hire onto the Employee record (stamping the Intent ID into a tenant-defined custom text field, by update when Hiring has already created the employee or on the create call when it has not) and records the link to the Hiring job opening on its own side while the role is open.

Reference
API at a glance

The public API facts composerID's adapter relies on. Tenant-specific details (custom fields, picklists, approval chains) are confirmed during connection and folded into the MappingProfile.

AuthenticationAPI key over HTTP Basic: the key is the username and any string is the password. Keys are generated per user from that user's account settings and inherit that user's access level, so publishing runs as a dedicated service user with the minimum permissions. OpenID Connect and OAuth are offered to Marketplace partner apps; a customer integration uses API keys.
API styleREST, JSON or XML selected by the Accept header (or a format query parameter), company-domain-scoped URL path. Updates are POSTs to the resource (POST /v1/employees/{id}), not PUT. Tabular history lives in named tables on the Employee (jobInfo, employmentStatus, compensation and others listed by GET /v1/meta/tables).
Base URLhttps://api.bamboohr.com/api/gateway.php/{companyDomain}/v1
Objectsemployees (stock fields and tenant custom fields; GET /v1/meta/fields lists both), employee tables (jobInfo, employmentStatus, compensation, emergencyContacts, dependents; GET /v1/meta/tables), employees/changed, employees/directory, reports (saved reports and POST /v1/reports/custom over any fields), time off (requests, balances, policies), files, webhooks, applicant_tracking (jobs, applications, statuses, locations)
Events / webhooksPermissioned webhooks are created through the API (POST /v1/webhooks with name, url, monitorFields, postFields, format, frequency and limit; GET /v1/webhooks/monitor_fields lists what can be monitored). Deliveries are signed HMAC-SHA256 over the body plus timestamp with the privateKey returned on create, carried in X-BambooHR-Signature and X-BambooHR-Timestamp headers (confirm header names and the exact signed string against the webhooks guide at onboarding). Account-level webhooks can also be configured in the UI by an administrator. There is no webhook for Hiring job or application events; those, and any missed employee changes, are polled with GET /v1/employees/changed?since= and the applicant_tracking reads.
Rate limitsNo fixed request rate is published. Throttled or overloaded calls return 429 or 503; back off and retry. A custom report returns every employee in one response, so prefer one report over per-employee GETs when reconciling. Indicative until confirmed at onboarding.
Readiness
Docs confidence: Public

“Docs confidence” describes how deterministic our mapping templates can be before we connect to a tenant. Even with public docs, implementations vary, especially around custom fields, approval flows and object extensions.

Deterministic mapping

Common Workforce Model fields map to known API fields. Best for standard objects (requisitions, assignments, timesheets, POs).

Tenant discovery

composerID can scan tenant configuration (custom fields, picklists, required fields) where the platform permits it, then generate a tenant‑specific MappingProfile.

Enrichment loop

If the target platform requires a field the Intent record doesn't yet have, composerID emits an enrichment_request back to the intake layer.

Mapping
Minimum viable mapping for BambooHR

An opinionated baseline. The platform adapter enforces additional requirements via preflight. “Tenant required” fields are discovered during connection and added to the MappingProfile.

Object Canonical fields Platform target Required status Notes
Employee (new hire)
Create or update the hired worker record
role_title (jobTitle), department, division, location, start_date (hireDate), employment_status POST /v1/employees/ (create; id returned in the Location header) or POST /v1/employees/{id} (update), then rows on the jobInfo and employmentStatus tables Required Only firstName and lastName are required by the API; hireDate, jobTitle, department, division and location can be sent on the create. When the tenant hires through the Hiring module BambooHR creates the Employee itself, so composerID updates that record rather than creating a second one. Compensation and status history are separate table rows. Stock field names are on the vendor's list-of-field-names page.
Intent ID correlation
Carry the Intent ID
intent_id -> employee custom text field (tenant-created in Settings; numeric id from GET /v1/meta/fields, custom fields carry no alias) Custom field on the Employee record, written on POST /v1/employees/ or POST /v1/employees/{id}, read back with GET /v1/employees/{id}?fields={fieldId} or included in POST /v1/reports/custom Required Custom fields cannot be created through the API; onboarding names the field (for example composerID), fixes its numeric field id in the connector configuration and confirms the service user can see and edit it. Reverse lookup is a filter over a custom report that includes the field (the report body only filters on lastChanged), not a server-side query. Deep link to the employee page is illustrative until confirmed, since the BambooHR employee id must first be resolved from the Intent ID.
Job Opening (Hiring)
Link the open role
job_opening_id, title, department, location, status GET /v1/applicant_tracking/jobs (statusGroups filter), GET /v1/applicant_tracking/applications Read scope only The public reference exposes no endpoint to create a job opening; Hiring writes are limited to adding an applicant (POST /v1/applicant_tracking/application) and changing an application status. The opening is raised in the Hiring UI and composerID records the linkage (Intent ID to job id) on its side. Confirm at onboarding that the tenant's plan includes Hiring and that the service user holds Hiring access.
Employee field webhook
Close the loop on the hire
employee id, hireDate, employmentStatus, jobTitle, plus the Intent ID custom field in postFields POST /v1/webhooks (monitorFields, postFields, frequency, limit) Recommended Monitor hireDate and employmentStatus and include the Intent ID custom field in postFields so every delivery correlates without a follow-up read. Verify the HMAC-SHA256 signature with the webhook's privateKey before processing; poll GET /v1/employees/changed?since= to backfill anything missed.
Idempotency & drift: publish + reconcileExpand

Publish operations are idempotent using a deterministic key {intent_id}-{intent_version}-{target_system}. Because humans can change records inside the platform, composerID supports reconciliation: it compares the platform record snapshot to the canonical intent and flags drift.

Tenant specifics
Custom fields & unique mapping

Real deployments rely on program-specific custom fields (for compliance, approvals, GL coding, rate rules or supplier constraints). composerID is designed to generate tenant‑specific mappings rather than forcing you to redesign your intake.

How scanning works

High-level flow

connect_destination() → read required fields + picklists (where permitted) → detect custom fields / extensions → build MappingProfile + validation rules → preflight intent against tenant requirements

Important: where this platform is tenant-definedExpand

Only the tenant can tell us three things. First, the Intent ID custom field: an administrator creates it in Settings before publishing starts, and its numeric field id (custom fields have no alias) is read from GET /v1/meta/fields and fixed in the connector configuration; the field must sit on a tab the service user can edit. Second, the service user itself: API keys carry the permissions of the user who generated them, so provision a dedicated user with employee create and edit, custom report and webhook rights only, and Hiring read access if the linkage to job openings is wanted. Third, how hires arrive: whether the tenant creates employees from Hiring (composerID updates the record BambooHR made) or expects composerID to create them, and whether the plan exposes applicant_tracking at all. Reverse lookup from Intent ID to employee runs through a custom report, since the API has no server-side filter on custom fields. Webhook signature details and any numeric rate limit are confirmed against the live tenant at onboarding.
