Why teams connect Klaviyo and Ramp
Connect the financial records in Ramp with the work happening in Klaviyo, so both stay current without exports or copy-paste.
Ramp holds the financial truth: who the customers are, what they were billed, what they paid. Klaviyo is where part of the day-to-day work happens, and that work often involves the same customers and transactions. Without a live connection, the two drift apart, and people end up answering questions from stale copies.
Stacksync keeps Vendors, Funds (Spend Controls), General Ledger Accounts, Transactions in Ramp and Profiles, Lists, Segments, Events in Klaviyo in sync, bi-directionally and in real time. Whatever records Klaviyo keeps and whatever events it produces, the overlap with Ramp is mapped field by field, and a change on either side shows up on the other within seconds.
There is no middleware to build, no API rate limits to babysit, and no nightly job that leaves the morning running on yesterday's data.
Common use cases
- 01 Mirror Bills and their approval and payment state into an AP or ERP system, marking each one ready-to-sync then synced to keep both ledgers reconciled.
- 02 Read Reimbursements into a finance database for cross-entity expense reporting and reconciliation without manual CSV exports.
- 03 Sync customer profiles between Klaviyo and the CRM or warehouse so segments can use fields beyond storefront data
- 04 Push offline, ERP, or subscription order events into Klaviyo as metrics to trigger post-purchase and win-back flows
Common sync patterns
Where Klaviyo tracks people or companies: one identity
A customer's details updated in either system update the other, so finance and the rest of the business stop maintaining two versions of the same customer.
Where Klaviyo handles customer conversations: billing context in view
Front-line teams see invoice and payment status from Ramp next to the customer they are helping, without logging into the finance system.
Where Klaviyo collects payments or triggers charges: events land in Ramp
Payment and charge activity flows into Ramp as it happens, so the books reflect reality without manual reconciliation.
What you can sync between Klaviyo 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.
| Klaviyo objects | Ramp objects | How this pairing syncs | |
|---|---|---|---|
| Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. | Bills Accounts-payable bills; created, updated, approved, and paid, then posted ready-to-sync and synced to accounting. | Profiles is specific to Klaviyo and Bills to Ramp — each maps to any object or custom field on the other side. | |
| Lists Static audience memberships sync in from CRMs and forms for targeting. | Vendors Supplier records under the accounting namespace; uploaded and updated for AP matching and payments. | Lists is specific to Klaviyo and Vendors to Ramp — each maps to any object or custom field on the other side. | |
| Segments Dynamic audiences are readable so other tools can mirror who qualifies. | Funds (Spend Controls) Spend controls governing card usage; read and created via the funds API to enforce budgets per user, department, or program. | Segments is specific to Klaviyo and Funds (Spend Controls) to Ramp — each maps to any object or custom field on the other side. | |
| Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows. | General Ledger Accounts Chart-of-accounts entries uploaded from the ERP; accounting codings are posted back against transactions and bills. | Events is specific to Klaviyo and General Ledger Accounts to Ramp — each maps to any object or custom field on the other side. | |
| Metrics Event type definitions organize the activity stream used in segmentation and attribution. | Transactions Card purchase records with merchant, amount, and state; read for spend/GL sync and written back via accounting codings and sync status. | Metrics is specific to Klaviyo and Transactions to Ramp — each maps to any object or custom field on the other side. | |
| Campaigns Email and SMS sends expose performance data for warehouse-based reporting. | Cards Physical and virtual card records; created and managed through the API to provision or suspend cardholder spend. | Campaigns is specific to Klaviyo and Cards to Ramp — each maps to any object or custom field on the other side. |
How changes propagate between Klaviyo 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.
Klaviyo Ramp Sub-second propagation
DetectionKlaviyo notifies Stacksync of record changes through webhook events. Polling on updated timestamps.
DeliveryEach detected change is written to Ramp through its API, with automatic retries and rate-limit backoff.
Ramp Klaviyo 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.

Rate-limit considerations
- Klaviyo: Per-endpoint burst and steady rate limits apply.
- 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.

FAQ
Klaviyo and Ramp integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Klaviyo and Ramp: authenticate both systems, choose the objects to sync (such as Klaviyo's Profiles and Lists), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Klaviyo and Ramp: Where Klaviyo tracks people or companies: one identity; Where Klaviyo handles customer conversations: billing context in view; Where Klaviyo collects payments or triggers charges: events land in Ramp. A customer's details updated in either system update the other, so finance and the rest of the business stop maintaining two versions of the same customer.

Klaviyo: REST API compliant with the JSON:API specification. Authentication: OAuth 2.0 for apps or private API keys. Ramp: 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). Stacksync manages authentication, retries, and rate limits on both sides.
-
Ramp: Rate limited to 200 requests per 10-second rolling window per source IP; a 429 is returned on exceed (higher limits available on request), so historical backfills must be paced with keyset pagination. Klaviyo: Profiles accept arbitrary custom properties, and events are append-only records tied to named metrics, which together form the segmentation model external data is synced into. Stacksync's field mapping accounts for these differences between Klaviyo and Ramp without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Klaviyo and Ramp records are not retained after a sync operation.
