Connect Lever and BambooHR to Build a Hire-to-Onboard Pipeline That Actually Works
When an offer is accepted in Lever, candidate data flows straight into BambooHR — no manual re-entry, no delays, no copy-paste errors.
Lever + BambooHR integration
Lever handles recruiting. BambooHR handles everything that happens once someone's hired. Together they cover the full arc from first application to long-term employee, but without an integration, there's an ugly gap right in the middle — the moment a recruiter closes a hire and someone has to manually move all that data over. That handoff is tedious, error-prone, and completely avoidable. Connecting Lever and BambooHR through tray.ai means every accepted offer automatically becomes a new employee record, so your People Ops team can focus on actual people instead of copy-paste work.
When recruiters close a hire in Lever, the clock starts on onboarding immediately. Every hour spent manually re-entering candidate details — name, contact info, role, compensation, start date — into BambooHR is an hour of delay in provisioning equipment, scheduling orientation, and making new hires feel welcome. That's before you account for the typos and transcription errors that ripple into payroll, org charts, and benefits enrollment. Integrating Lever with BambooHR via tray.ai creates a reliable, automated bridge that fires the moment a candidate's stage changes to 'Hired,' pushing clean employee data directly into BambooHR and kicking off onboarding workflows automatically. Recruiting and HR stay in sync, new hires get a better first impression, and leadership gets a single source of truth for workforce data from offer letter to anniversary.
Automate & integrate Lever + BambooHR
Automating Lever and BambooHR business processes or integrating data is made easy with Tray.ai.
Use case
Automated New Employee Record Creation on Hire
When a candidate is marked as hired in Lever, tray.ai automatically creates a new employee profile in BambooHR, filling in job title, department, compensation, and anticipated start date. HR teams don't have to manually transcribe offer details after every close, and recruiting doesn't have to send a follow-up email to confirm the handoff happened. Both sides stay in sync without a single spreadsheet changing hands.
- Eliminate duplicate data entry between recruiting and HR systems
- Cut the time from offer acceptance to onboarding readiness by hours or days
- Reduce errors in sensitive compensation and personal data transfers
Use case
Onboarding Task Kickoff Triggered by Lever Stage Change
The moment a candidate advances to 'Hired' in Lever, tray.ai triggers a BambooHR onboarding workflow — automatically assigning tasks to IT, Facilities, and the hiring manager before day one arrives. Equipment provisioning, system access, and workspace setup all begin right after the offer is accepted, not three days later when someone remembers to send the emails. New hires show up to a prepared environment instead of waiting for logistics to catch up.
- Launch onboarding checklists automatically without HR manually kicking them off
- Assign onboarding tasks consistently across every new hire
- Start logistics on day zero so new hires are productive faster
Use case
Offer and Compensation Data Sync for Payroll Readiness
tray.ai captures compensation and role data from Lever offers and maps it directly into the right BambooHR fields for payroll and benefits setup, so payroll administrators have accurate information before the employee's first pay cycle. For organizations hiring at volume, even small data discrepancies can cascade into payroll corrections or benefits enrollment problems. This integration keeps financial data accurate and audit-ready from the start.
- Ensure payroll and compensation data is accurate from day one
- Reduce payroll corrections caused by manual transcription errors
- Speed up benefits enrollment with pre-populated employee data
Use case
Candidate Source Attribution Preserved in BambooHR
Lever tracks where every candidate came from — job board, referral, LinkedIn, direct outreach — and tray.ai carries that attribution into BambooHR custom fields so HR and leadership can analyze which channels actually produce long-term employees. Without this, source data typically disappears at the ATS-to-HRIS handoff, making it impossible to connect recruiting spend to retention outcomes. Keeping that data intact means smarter workforce planning and more defensible recruiting budget decisions.
- Retain candidate source data throughout the employee lifecycle
- Report on which sourcing channels produce your highest-retention hires
- Support recruiting budget decisions with full-funnel visibility
Use case
Rejected or Withdrawn Candidate Record Cleanup
When a late-stage candidate is rejected or withdraws in Lever, tray.ai can trigger cleanup actions in BambooHR if a preliminary record was already created — so your HRIS doesn't quietly fill up with ghost profiles for people who never started. Teams that pre-create BambooHR records in anticipation of a hire run into this constantly. Automated cleanup keeps your employee directory accurate and your headcount reporting trustworthy.
- Keep BambooHR free of incomplete or abandoned employee records
- Maintain accurate headcount and org chart data in real time
- Reduce audit and compliance risk from orphaned profiles
Use case
Rehire Detection and Record Reconciliation
When a candidate is marked as hired in Lever, tray.ai checks BambooHR for any existing employee records before creating a new profile — catching potential rehires and routing them through a reconciliation workflow instead of generating duplicates. This matters especially for organizations with high contractor-to-employee conversion rates or seasonal rehire patterns. Handling rehires correctly preserves historical employment data and keeps benefits history intact.
- Prevent duplicate employee profiles from rehire scenarios
- Preserve historical employment and benefits data for returning employees
- Route rehire cases to HR for review with full context from both systems
Challenges Tray.ai solves
Common obstacles when integrating Lever and BambooHR — and how Tray.ai handles them.
Challenge
Field Mapping Complexity Between ATS and HRIS Schemas
Lever and BambooHR use fundamentally different data models. Lever is built around opportunities, candidates, and postings; BambooHR organizes data around employees, departments, and positions. Translating between these schemas without a flexible integration layer means either writing brittle custom code or accepting incomplete data transfers where fields get dropped or land in the wrong place.
How Tray.ai helps
tray.ai's visual data mapper and built-in transformation tools let you precisely map every Lever candidate and offer field to its correct BambooHR counterpart with no code required. Custom logic handles edge cases like department name normalization, compensation structure differences, and conditional field mappings based on employment type.
Challenge
Triggering Integrations at the Right Hiring Stage
Not every stage change in Lever should fire a BambooHR record creation. Create an employee profile too early and you're cluttering the system with speculative records; trigger too late and you're delaying onboarding. Pinning down the right hiring signal — offer signed, background check cleared, or a custom stage — requires configurable trigger logic that basic point-to-point tools simply don't have.
How Tray.ai helps
tray.ai's workflow logic lets you configure precise trigger conditions using Lever's stage names, offer statuses, or custom field values. You can build conditional branches that handle different hiring workflows for full-time, contractor, or intern hires, so BambooHR actions only fire at exactly the right moment.
Challenge
Handling Failed or Reversed Hires Gracefully
When a hire falls through after a BambooHR record has already been created — failed background check, rescinded offer, candidate no-show — the HRIS is left with an orphaned incomplete employee profile that corrupts headcount reports and org charts. Most simple integrations create records on hire but have no way to handle the reversal.
How Tray.ai helps
tray.ai workflows can listen for reversal events in Lever and trigger corresponding cleanup or status-update actions in BambooHR — archiving the record, flagging it for HR review, or deleting it based on your configured business rules. Your HRIS stays clean without HR having to intervene manually.
Templates
