Why teams connect Azure Cosmos DB and Ramp

Work with Ramp's financial data straight from Azure Cosmos DB: 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 Stored procedures and triggers, Databases, Containers, Items (JSON documents) in Azure Cosmos DB and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Azure Cosmos DB, 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 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 Mirror Cosmos DB items into Postgres so teams can query operational data with standard SQL.
  • 04 Two-way sync between a Cosmos DB-backed product catalog and a PIM or commerce platform.

Common sync patterns

React to financial events

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

Internal tools without API plumbing

Build dashboards and back-office tools directly on Azure Cosmos DB; Stacksync handles the API calls, rate limits, and retries against Ramp.

What you can sync between Azure Cosmos DB 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.

Azure Cosmos DB objects Ramp objects How this pairing syncs
Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation. Users Employee and cardholder records; invited, updated, and deactivated, commonly synced from an HRIS or identity provider. Stored procedures and triggers is specific to Azure Cosmos DB and Users to Ramp — each maps to any object or custom field on the other side.
Databases Top-level namespaces that scope containers and throughput provisioning. Departments Org groupings for cost-center and GL allocation; pushed from an ERP/HRIS and referenced by cards and transactions. Databases is specific to Azure Cosmos DB and Departments to Ramp — each maps to any object or custom field on the other side.
Containers The unit of partitioning and throughput; each container maps to a synced collection. Reimbursements Out-of-pocket expense claims; read for reporting and marked ready-to-sync then synced to the ERP. Containers is specific to Azure Cosmos DB and Reimbursements to Ramp — each maps to any object or custom field on the other side.
Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed. Bills Accounts-payable bills; created, updated, approved, and paid, then posted ready-to-sync and synced to accounting. Items (JSON documents) is specific to Azure Cosmos DB and Bills to Ramp — each maps to any object or custom field on the other side.
Partition keys Determine data distribution and must be included on writes for the sync to route items correctly. Vendors Supplier records under the accounting namespace; uploaded and updated for AP matching and payments. Partition keys is specific to Azure Cosmos DB and Vendors to Ramp — each maps to any object or custom field on the other side.
Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync. Funds (Spend Controls) Spend controls governing card usage; read and created via the funds API to enforce budgets per user, department, or program. Change feed entries is specific to Azure Cosmos DB and Funds (Spend Controls) to Ramp — each maps to any object or custom field on the other side.

How changes propagate between Azure Cosmos DB 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.

Azure Cosmos DB Ramp Sub-second propagation

DetectionChanges in Azure Cosmos DB are captured at the source via change data capture — no polling loop against its API. Built-in change feed exposing inserts and updates in order within each partition key range.

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

Ramp Azure Cosmos DB 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 Azure Cosmos DB 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.
