Why teams connect BambooHR and Ramp

Keep the employee, department, and cost records that Ramp and BambooHR share consistent in real time, so the finance system and the people system stop drifting apart.

Ramp runs the money side of the company: who gets paid, what it costs, and which part of the business the cost belongs to. BambooHR runs the people side: who works here, which team they sit in, and how their employment changes over time. The two overlap on the same people and the same org structure, because every employee is also a payee and every department is also a cost center. When that overlap is maintained by hand, a new hire, a transfer, or a termination has to be keyed twice, and the two systems start to disagree about who is active and where the cost lands.

Stacksync syncs Reimbursements, Bills, Vendors, Funds (Spend Controls) in Ramp with Departments and Divisions, Custom Tables, Reports, Employees in BambooHR bi-directionally and in real time. A person added, updated, or deactivated on either side appears on the other within seconds, with field-level mapping and conflict resolution in place of CSV exports and nightly batch jobs.

That matters most when money follows a people event. A hire that finance can pay, a leaver whose access ends, a transfer that redirects cost to the right team, all happen from one change instead of two, so headcount and spend reconcile from the same set of records.

Common use cases

  • 01 Read Reimbursements into a finance database for cross-entity expense reporting and reconciliation without manual CSV exports.
  • 02 Two-way sync Transactions and their accounting codings with a Postgres warehouse so finance analyzes spend in SQL and pushes GL categories and memos back to Ramp.
  • 03 Feed Compensation and custom-table data to a warehouse for HR analytics with field-level access control.
  • 04 Sync Employees and Employment Status to identity and IT systems so new hires are provisioned and departures deactivated automatically.

Common sync patterns

People-driven costs land in finance

Compensation, reimbursements, or other costs tied to a person on the BambooHR side flow into Ramp for posting, so the books reflect what people actually cost without manual re-entry.

New person becomes a known record in finance

When someone is added in BambooHR, a matching employee or payee record appears in Ramp, ready for payroll, expenses, or cost allocation without anyone rekeying the details.

One employee identity

A person's name, ID, or contact details corrected in either system update the other, so finance and HR reference the same person instead of maintaining two versions.

What you can sync between BambooHR and Ramp

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

BambooHR objects Ramp objects How this pairing syncs
Time Off Requests, balances, and policies; read for absence calendars and capacity planning, with approved requests written from an external scheduling tool. Bills Accounts-payable bills; created, updated, approved, and paid, then posted ready-to-sync and synced to accounting. Time Off is specific to BambooHR and Bills to Ramp — each maps to any object or custom field on the other side.
Employment Status Effective-dated hire, leave, and termination status; drives automated provisioning and deprovisioning in downstream identity and license systems. Vendors Supplier records under the accounting namespace; uploaded and updated for AP matching and payments. Employment Status is specific to BambooHR and Vendors to Ramp — each maps to any object or custom field on the other side.
Departments and Divisions Org-structure list values; synced to keep cost centers and team groupings consistent across ERP, identity, and analytics systems. Funds (Spend Controls) Spend controls governing card usage; read and created via the funds API to enforce budgets per user, department, or program. Departments and Divisions is specific to BambooHR and Funds (Spend Controls) to Ramp — each maps to any object or custom field on the other side.
Custom Tables Company-specific effective-dated tables (assets, training, certifications); rows read and written so custom HR data isn't trapped in the HRIS. General Ledger Accounts Chart-of-accounts entries uploaded from the ERP; accounting codings are posted back against transactions and bills. Custom Tables is specific to BambooHR and General Ledger Accounts to Ramp — each maps to any object or custom field on the other side.
Reports Saved company reports retrievable via API; read out on a schedule to feed a warehouse without rebuilding field-by-field queries. Transactions Card purchase records with merchant, amount, and state; read for spend/GL sync and written back via accounting codings and sync status. Reports is specific to BambooHR and Transactions to Ramp — each maps to any object or custom field on the other side.
Employees The core person record with personal and work fields; read out to identity, payroll, and IT systems, and written back from recruiting or onboarding tools. Cards Physical and virtual card records; created and managed through the API to provision or suspend cardholder spend. Employees is specific to BambooHR and Cards to Ramp — each maps to any object or custom field on the other side.

How changes propagate between BambooHR and Ramp

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

BambooHR Ramp Sub-second propagation

DetectionBambooHR notifies Stacksync of record changes through webhook events. The Get Updated Employee IDs endpoint (last-changed timestamps) returns employees inserted, updated, or deleted since a cursor for efficient polling.

DeliveryEach detected change is written to Ramp through its API, with automatic retries and rate-limit backoff.

Ramp BambooHR Sub-second propagation

DetectionRamp notifies Stacksync of record changes through webhook events. Signed webhooks (HMAC-SHA256 X-Ramp-Signature) for bill, transaction, reimbursement, vendor, and user events.

DeliveryEach detected change is written to BambooHR through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • BambooHR: Requests are rate-limited per API key with standard REST throttling (429 on excess); bulk reads are best done through saved Reports or the updated-IDs delta endpoint rather than per-employee calls.
  • Ramp: 200 requests per 10-second rolling window per source IP; exceeding it returns 429 Too Many Requests, and requests running over 60 seconds return 504. Results use keyset pagination (follow the page.next URL / start cursor); higher limits can be requested from support.

Ramp

Integration surface
REST API (Developer API v1)
Authentication
OAuth 2.0: exchange client_id/client_secret (HTTP Basic) at api.ramp.com/developer/v1/token for scoped bearer tokens; client_credentials grant for server-to-server and authorization_code for user-delegated access; scopes follow resource:permission (e.g. transactions:read, bills:write, accounting:write).
Change detection
Signed webhooks (HMAC-SHA256 X-Ramp-Signature) for bill, transaction, reimbursement, vendor, and user events; otherwise poll incrementally (synced_after on transactions, from_created_at on bills) with keyset pagination, or read the audit-logs/events feed.
