Why teams connect ClickHouse and Ramp

Land the financial records from Ramp in ClickHouse continuously, and write results back, without building or maintaining a pipeline.

Finance data belongs in the warehouse: revenue, invoices, payments, and customers joined with everything else the business measures. Getting it there usually means an extraction pipeline that breaks quietly and delivers yesterday's numbers.

Stacksync syncs Transactions, Cards, Users, Departments from Ramp into tables in ClickHouse in real time, and the connection works in both directions: values computed in ClickHouse can be written back to fields in Ramp where you want them operational. Schema changes are handled, API limits are managed, and the sync is something you configure rather than code you maintain.

Common use cases

  • 01 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.
  • 02 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.
  • 03 Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.
  • 04 Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.

Common sync patterns

Write-back of computed fields

Scores or segments computed in ClickHouse, like payment-risk flags or customer tiers, sync back onto records in Ramp where the finance team can act on them.

Queryable history for audit and reconciliation

A continuously synced copy in ClickHouse gives you a durable, queryable record of financial data for month-end and audit questions.

Finance analytics without ETL

Invoices, payments, and customer records from Ramp arrive in ClickHouse as queryable tables, current within seconds instead of a day behind.

What you can sync between ClickHouse 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.

ClickHouse objects Ramp objects How this pairing syncs
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Cards Physical and virtual card records; created and managed through the API to provision or suspend cardholder spend. Materialized views is specific to ClickHouse and Cards to Ramp — each maps to any object or custom field on the other side.
Distributed tables Query-routing tables over cluster shards in self-managed deployments. Users Employee and cardholder records; invited, updated, and deactivated, commonly synced from an HRIS or identity provider. Distributed tables is specific to ClickHouse and Users to Ramp — each maps to any object or custom field on the other side.
Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Departments Org groupings for cost-center and GL allocation; pushed from an ERP/HRIS and referenced by cards and transactions. Dictionaries is specific to ClickHouse and Departments to Ramp — each maps to any object or custom field on the other side.
Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Reimbursements Out-of-pocket expense claims; read for reporting and marked ready-to-sync then synced to the ERP. Tables (MergeTree family) is specific to ClickHouse and Reimbursements to Ramp — each maps to any object or custom field on the other side.
Databases Namespaces that group tables and scope permissions for sync users. Bills Accounts-payable bills; created, updated, approved, and paid, then posted ready-to-sync and synced to accounting. Databases is specific to ClickHouse and Bills to Ramp — each maps to any object or custom field on the other side.
Views Saved queries used as curated, read-only sync sources. Vendors Supplier records under the accounting namespace; uploaded and updated for AP matching and payments. Views is specific to ClickHouse and Vendors to Ramp — each maps to any object or custom field on the other side.

How changes propagate between ClickHouse 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.

ClickHouse Ramp Interval-based propagation

DetectionStacksync polls ClickHouse for changes on an incremental schedule, reading only records changed since the previous pass. No log-based CDC for consumers.

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

Ramp ClickHouse 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 applied to ClickHouse as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • 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.

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.
