Why teams connect Google Cloud Spanner and Ramp

Work with Ramp's financial data straight from Google Cloud Spanner: read it with ordinary queries, write to it from your own code, and let Stacksync keep both sides consistent.

Engineers need finance data more often than finance systems make it easy to get: for internal tools, reporting services, or logic that reacts to invoices and payments. Working through the vendor API means rate limits, pagination, and glue code that has to be maintained forever.

Stacksync mirrors Reimbursements, Bills, Vendors, Funds (Spend Controls) from Ramp into Tables, Rows, Interleaved tables, Secondary indexes in Google Cloud Spanner and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Google Cloud Spanner, and rows your code writes or updates flow back into Ramp with validation, so the finance system stays the system of record.

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 Run a two-way sync between Spanner and a SaaS tool so edits made by ops teams land back in the application database.
  • 04 Consolidate data from a globally distributed Spanner deployment into regional business systems.

Common sync patterns

Write back safely

Updates written to the synced tables in Google Cloud Spanner propagate into Ramp, so automations can create or correct finance records without custom integration code.

React to financial events

Changes in Ramp appear in Google Cloud Spanner as row changes, so you can trigger downstream logic with the database tooling you already use.

Query finance data like any other data

Customers, invoices, and payments from Ramp live in Google Cloud Spanner as regular tables or collections your team can join, index, and query.

What you can sync between Google Cloud Spanner 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.

Google Cloud Spanner objects Ramp objects How this pairing syncs
Rows The unit of read and write in each sync cycle, keyed by primary key. Cards Physical and virtual card records; created and managed through the API to provision or suspend cardholder spend. Rows is specific to Google Cloud Spanner and Cards to Ramp — each maps to any object or custom field on the other side.
Interleaved tables Child rows physically co-located with parents; synced as related records. Users Employee and cardholder records; invited, updated, and deactivated, commonly synced from an HRIS or identity provider. Interleaved tables is specific to Google Cloud Spanner and Users to Ramp — each maps to any object or custom field on the other side.
Secondary indexes Used to make incremental read queries efficient on non-key columns. Departments Org groupings for cost-center and GL allocation; pushed from an ERP/HRIS and referenced by cards and transactions. Secondary indexes is specific to Google Cloud Spanner and Departments to Ramp — each maps to any object or custom field on the other side.
Change streams Capture inserts, updates, and deletes for log-style change data capture. Reimbursements Out-of-pocket expense claims; read for reporting and marked ready-to-sync then synced to the ERP. Change streams is specific to Google Cloud Spanner and Reimbursements to Ramp — each maps to any object or custom field on the other side.
Views Read-only projections useful for shaping data before it leaves Spanner. Bills Accounts-payable bills; created, updated, approved, and paid, then posted ready-to-sync and synced to accounting. Views is specific to Google Cloud Spanner and Bills to Ramp — each maps to any object or custom field on the other side.
Databases Top-level containers that scope schema and sync configuration. Vendors Supplier records under the accounting namespace; uploaded and updated for AP matching and payments. Databases is specific to Google Cloud Spanner and Vendors to Ramp — each maps to any object or custom field on the other side.

How changes propagate between Google Cloud Spanner 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.

Google Cloud Spanner Ramp Sub-second propagation

DetectionChanges in Google Cloud Spanner are captured at the source via change data capture — no polling loop against its API. Change streams (log-style CDC), or timestamp-based polling queries.

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

Ramp Google Cloud Spanner 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 Google Cloud Spanner as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Google Cloud Spanner: Throughput is bounded by the instance's provisioned compute capacity rather than a fixed API quota.
  • 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.
