Why teams connect OpenSearch and Ramp

Work with Ramp's financial data straight from OpenSearch: 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 Transactions, Cards, Users, Departments from Ramp into Ingest pipelines, Data streams, Snapshots, Indexes in OpenSearch and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against OpenSearch, 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 Stream CRM records such as accounts, contacts, and tickets into OpenSearch to power internal search across customer data.
  • 04 Sync product catalogs from an ERP or database into the indexes that back storefront search.

Common sync patterns

Write back safely

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

React to financial events

Changes in Ramp appear in OpenSearch 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 OpenSearch as regular tables or collections your team can join, index, and query.

What you can sync between OpenSearch 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.

OpenSearch objects Ramp objects How this pairing syncs
Snapshots Backup artifacts, relevant when reseeding an index from a repository Departments Org groupings for cost-center and GL allocation; pushed from an ERP/HRIS and referenced by cards and transactions. Snapshots is specific to OpenSearch and Departments to Ramp — each maps to any object or custom field on the other side.
Indexes The core container; synced records land in indexes with defined mappings Reimbursements Out-of-pocket expense claims; read for reporting and marked ready-to-sync then synced to the ERP. Indexes is specific to OpenSearch and Reimbursements to Ramp — each maps to any object or custom field on the other side.
Documents JSON records written via the index and bulk APIs and read via search queries Bills Accounts-payable bills; created, updated, approved, and paid, then posted ready-to-sync and synced to accounting. Documents is specific to OpenSearch and Bills to Ramp — each maps to any object or custom field on the other side.
Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills Vendors Supplier records under the accounting namespace; uploaded and updated for AP matching and payments. Index aliases is specific to OpenSearch and Vendors to Ramp — each maps to any object or custom field on the other side.
Index templates Mapping and settings presets applied to new indexes a sync creates Funds (Spend Controls) Spend controls governing card usage; read and created via the funds API to enforce budgets per user, department, or program. Index templates is specific to OpenSearch and Funds (Spend Controls) to Ramp — each maps to any object or custom field on the other side.
Ingest pipelines Server-side processors that transform documents as they are written General Ledger Accounts Chart-of-accounts entries uploaded from the ERP; accounting codings are posted back against transactions and bills. Ingest pipelines is specific to OpenSearch and General Ledger Accounts to Ramp — each maps to any object or custom field on the other side.

How changes propagate between OpenSearch 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.

OpenSearch Ramp Interval-based propagation

DetectionStacksync polls OpenSearch for changes on an incremental schedule, reading only records changed since the previous pass. No native change feed.

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

Ramp OpenSearch 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 OpenSearch through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • OpenSearch: Throughput bounded by cluster sizing rather than fixed API quotas.
  • 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.
