Why teams connect Dynamo DB and Ramp

Work with Ramp's financial data straight from Dynamo 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 Funds (Spend Controls), General Ledger Accounts, Transactions, Cards from Ramp into Global Tables, Tables, Items, Attributes in Dynamo DB and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Dynamo 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 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 Mirror SaaS objects into DynamoDB items to serve low-latency lookups from production services.
  • 04 Consolidate multi-region Global Tables data into a single reporting store.

Common sync patterns

React to financial events

Changes in Ramp appear in Dynamo 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 Dynamo 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 Dynamo DB; Stacksync handles the API calls, rate limits, and retries against Ramp.

What you can sync between Dynamo 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.

Dynamo DB objects Ramp objects How this pairing syncs
Global Tables Multi-region replicas relevant when syncs must read from a specific region. Transactions Card purchase records with merchant, amount, and state; read for spend/GL sync and written back via accounting codings and sync status. Global Tables is specific to Dynamo DB and Transactions to Ramp — each maps to any object or custom field on the other side.
Tables The top-level containers a sync targets; each table is addressed independently. Cards Physical and virtual card records; created and managed through the API to provision or suspend cardholder spend. Tables is specific to Dynamo DB and Cards to Ramp — each maps to any object or custom field on the other side.
Items Schemaless records keyed by partition (and optional sort) key, mapped to rows or SaaS objects in syncs. Users Employee and cardholder records; invited, updated, and deactivated, commonly synced from an HRIS or identity provider. Items is specific to Dynamo DB and Users to Ramp — each maps to any object or custom field on the other side.
Attributes Per-item fields, including nested maps and lists, flattened or mapped during sync. Departments Org groupings for cost-center and GL allocation; pushed from an ERP/HRIS and referenced by cards and transactions. Attributes is specific to Dynamo DB and Departments to Ramp — each maps to any object or custom field on the other side.
Partition and Sort Keys The primary key pair used as the match key for bi-directional sync. Reimbursements Out-of-pocket expense claims; read for reporting and marked ready-to-sync then synced to the ERP. Partition and Sort Keys is specific to Dynamo DB and Reimbursements to Ramp — each maps to any object or custom field on the other side.
Global Secondary Indexes Alternate access paths used when sync queries filter on non-key attributes. Bills Accounts-payable bills; created, updated, approved, and paid, then posted ready-to-sync and synced to accounting. Global Secondary Indexes is specific to Dynamo DB and Bills to Ramp — each maps to any object or custom field on the other side.

How changes propagate between Dynamo 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.

Dynamo DB Ramp Sub-second propagation

DetectionChanges in Dynamo DB are captured at the source via change data capture — no polling loop against its API. Item-level change streams via DynamoDB Streams or Kinesis Data Streams integration.

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

Ramp Dynamo 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 Dynamo DB as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Dynamo DB: Throughput is governed by the table's provisioned or on-demand capacity mode.
  • 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.
