Overview
Moving from Teamtailor to BambooHR is an ATS-to-HRIS migration, not an ATS-to-ATS swap. Teamtailor is purpose-built for recruitment, employer branding, and candidate experience; BambooHR is an HRIS that covers the full employee lifecycle including hiring, onboarding, payroll, time off, and performance. We map Teamtailor Candidates into BambooHR Employees (using BambooHR's built-in ATS for application records), preserve job postings as requisitions, and resolve custom field schemas discovered during the scoping pass. Teamtailor's 50 req/10s API rate limit, cursor-based pagination on large collections, and absence of a custom field metadata endpoint all shape the extraction strategy. Triggers, automation rules, Interview Kits, and career site configurations do not migrate; we deliver a written inventory of these for the customer's admin to rebuild in BambooHR.

Object mapping
Each row shows how a Teamtailor object lands in BambooHR, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Teamtailor
Candidate
BambooHR
Employee
1:1Teamtailor Candidate records map to BambooHR Employee records. We extract name fields, email address, phone number, and address fields and map them to BambooHR's standard Employee fields. Candidate custom fields discovered during scoping are mapped to Employee Files categories rather than structured custom fields, since BambooHR stores extended candidate data as file attachments and category tags rather than typed fields. The BambooHR Employee record must exist before any linked Application record is created.
Teamtailor
Candidate
BambooHR
Application (BambooHR ATS)
1:1Teamtailor Job Applications map to BambooHR Application records when the customer's BambooHR plan includes the ATS module. Each Application is linked to the corresponding BambooHR Employee record created from the Candidate. Application status (active, rejected, hired) maps to BambooHR Application Status values, and the original application date is preserved. If the customer does not activate BambooHR ATS, applications are documented as Employee Files with an Application category attachment.
Teamtailor
Job
BambooHR
Job Requisition
1:1Teamtailor Job records map to BambooHR Job Requisitions via BambooHR's ATS module. We transfer job title, job status (open, paused, closed), department assignment, and job body content. Department is resolved against the BambooHR Department taxonomy created from Teamtailor Departments. Location maps to the BambooHR Location or Office object. Custom fields on job postings (discovered during scoping) are stored as Employee Files attachments against the Job Requisition or as custom fields if BambooHR ATS supports them for the customer's tier.
Teamtailor
Department
BambooHR
Department
1:1Teamtailor Departments export as a flat list and map directly to BambooHR Departments. The Teamtailor department ID is preserved in a BambooHR custom field for traceability. Department assignment on Jobs and Candidates migrates as a lookup reference to the corresponding BambooHR Department record.
Teamtailor
Location
BambooHR
Location / Office
1:1Teamtailor Locations map to BambooHR Location records. Geographic metadata (city, country) is preserved in the Location record. If the customer uses Teamtailor's multi-location feature on jobs, each location becomes a separate BambooHR Location linked to the Job Requisition.
Teamtailor
User (Hiring Team)
BambooHR
User
1:1Teamtailor Users (hiring managers and recruiters) map to BambooHR Users by email address. Owner assignments on Candidates, Jobs, and Applications are preserved by resolving the Teamtailor user ID to the corresponding BambooHR User. Any Teamtailor User without a matching BambooHR User goes to a reconciliation queue for the customer's admin to provision before the migration resumes.
Teamtailor
Custom Fields (Candidates)
BambooHR
Employee Files (categories)
lossyTeamtailor candidate custom fields are discovered by sampling records during scoping since Teamtailor exposes no metadata endpoint. Each discovered custom field is mapped to a corresponding Employee Files category in BambooHR. If Teamtailor's extended data migration setting is active (as recommended in the Teamtailor support article), custom field values transfer as structured data within the Employee Files category rather than plain text. The customer must create a default Resumes and applications category in BambooHR Employee Files before migration begins.
Teamtailor
Custom Fields (Job Postings)
BambooHR
Job Requisition Custom Fields or Notes
lossyTeamtailor job posting custom fields are scoped to the job object and differ from candidate custom fields. We map these to BambooHR ATS custom fields if available on the customer's plan tier, or to a Job Notes field as structured text. The mapping strategy is confirmed during the scoping discovery pass when the actual field inventory is reviewed.
Teamtailor
Uploads and Attachments
BambooHR
Employee Files
1:1Candidate resumes, cover letters, and portfolio files referenced in Teamtailor are downloaded from the Teamtailor API URLs and uploaded as Employee Files in BambooHR. The file type (resume, cover letter, portfolio) is mapped to a BambooHR Employee Files category. If Teamtailor's extended data migration is enabled, file names and metadata are preserved. We download files in parallel batches to manage the Teamtailor 50 req/10s rate limit and queue retries with exponential backoff for throttled requests.
Teamtailor
Interview Kits and Questions
BambooHR
Not migrated
1:1Teamtailor Interview Kits and structured interview questions are tied to jobs rather than candidates and are not exposed via a structured API endpoint for direct migration. We export kit names and associated question text as a written inventory document. BambooHR does not have a native Interview Kit feature, so the customer's admin rebuilds these using BambooHR's Workflow builder and document templates or a third-party interview scheduling tool like Calendly or Ashby.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Teamtailor gotchas
API rate limit of 50 requests per 10 seconds can stall bulk exports
Unbounded answers and actions endpoints return HTTP 500 on large datasets
Custom fields are not surfaced in a unified schema endpoint
Automation and trigger rules are not accessible via the public API
API versioning header is required on every request
BambooHR gotchas
Undocumented API rate limits can trigger 503 errors
Per-employee pricing model requires active record count verification
API credentials must be sent on every request to avoid extra round trips
Custom field schema varies per account and requires manual inventory
Document and attachment exports are not covered by standard report exports
Pair-specific challenges
Migration approach
Discovery and field inventory
We audit the Teamtailor account across custom field schemas (discovered via record sampling), pipeline stage definitions, active automations visible in the UI, department and location taxonomy, user roster, and file attachment volume. We simultaneously review the BambooHR account for existing Department and Location records, Employee Files category structure, and whether the ATS module is active. The discovery output is a written migration scope, a custom field mapping table, and a BambooHR Employee Files category checklist for the customer's admin to create before migration.
Authentication and API preparation
We configure Teamtailor API access with an Admin Read scope API key and send the required X-Api-Version: 20240404 header on every request. We configure BambooHR API access using the customer's subdomain and an API key with read-write permissions for Employee, Job Requisition, and Employee Files endpoints. We validate both API credentials against a lightweight endpoint before the full export begins.
Taxonomy and user pre-creation
We export Teamtailor Departments and Locations and create matching BambooHR Department and Location records first, before any candidate or job data. We export Teamtailor Users and reconcile by email against existing BambooHR Users, flagging any owners without a match in the reconciliation queue. The customer's BambooHR admin provisions missing Users before the record migration phase begins, since Owner references are required on most BambooHR ATS objects.
Candidate and file extraction with rate-limit pacing
We extract Teamtailor Candidates in cursor-paginated batches, staying within the 50 req/10s limit using a rolling worker queue. Resume and attachment files are fetched in parallel batches with exponential backoff on 429 responses. Custom field values are captured from each candidate record during extraction and stored in a staging structure mapped to the target BambooHR Employee Files category. The extraction emits a record count and attachment count reconciliation report.
Employee and Application write to BambooHR
We write Candidates as BambooHR Employees in batches, resolving Department and Location lookups from the pre-created taxonomy. Application records are written next, linked to the corresponding Employee. Employee Files attachments (resumes, cover letters) are uploaded to the appropriate category. Custom field values are written as structured Employee Files or as category-tagged notes depending on the mapping confirmed during discovery. Each write phase emits a reconciliation report before the next phase begins.
Cutover, validation, and automation handoff
We freeze writes to Teamtailor during the cutover window, run a delta migration of any records created or modified since the initial export, then enable BambooHR as the system of record. We deliver the automation and trigger inventory document to the customer's admin team. We support a one-week hypercare window where we resolve any reconciliation discrepancies raised by the customer's team. Workflow rebuild in BambooHR is outside migration scope and is handled by the customer's admin or a BambooHR partner.
