Why teams connect Amazon RDS and Ramp

Work with Ramp's financial data straight from Amazon RDS: 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 Views, Columns, Primary and Unique Keys, Read Replicas in Amazon RDS and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Amazon RDS, 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 RDS tables so product features can join business data with application data in one query
  • 04 Keep an RDS reporting database hydrated from operational tools without maintaining ETL jobs

Common sync patterns

Internal tools without API plumbing

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

Write back safely

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

React to financial events

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

What you can sync between Amazon RDS 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.

Amazon RDS objects Ramp objects How this pairing syncs
Tables The core sync target; rows map to records in connected SaaS systems. Vendors Supplier records under the accounting namespace; uploaded and updated for AP matching and payments. Tables is specific to Amazon RDS and Vendors to Ramp — each maps to any object or custom field on the other side.
Views Read-side projections exposed to outbound syncs. Funds (Spend Controls) Spend controls governing card usage; read and created via the funds API to enforce budgets per user, department, or program. Views is specific to Amazon RDS and Funds (Spend Controls) to Ramp — each maps to any object or custom field on the other side.
Columns Field-level mapping targets, typed per the underlying engine. General Ledger Accounts Chart-of-accounts entries uploaded from the ERP; accounting codings are posted back against transactions and bills. Columns is specific to Amazon RDS and General Ledger Accounts to Ramp — each maps to any object or custom field on the other side.
Primary and Unique Keys Match keys for idempotent upserts. Transactions Card purchase records with merchant, amount, and state; read for spend/GL sync and written back via accounting codings and sync status. Primary and Unique Keys is specific to Amazon RDS and Transactions to Ramp — each maps to any object or custom field on the other side.
Read Replicas Low-impact read endpoints often used as the source side of a sync. Cards Physical and virtual card records; created and managed through the API to provision or suspend cardholder spend. Read Replicas is specific to Amazon RDS and Cards to Ramp — each maps to any object or custom field on the other side.
Stored Procedures Engine-specific logic that can react to synced rows. Users Employee and cardholder records; invited, updated, and deactivated, commonly synced from an HRIS or identity provider. Stored Procedures is specific to Amazon RDS and Users to Ramp — each maps to any object or custom field on the other side.

How changes propagate between Amazon RDS 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.

Amazon RDS Ramp Sub-second propagation

DetectionChanges in Amazon RDS are captured at the source via change data capture — no polling loop against its API. Engine-native log-based CDC: MySQL/MariaDB binlog, PostgreSQL logical replication, SQL Server CDC.

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

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

Rate-limit considerations

  • Amazon RDS: No API rate limits; throughput depends on instance class, storage IOPS, and connection limits.
  • 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.

How the Amazon RDS and Ramp connectors work

Amazon RDS

SQL wire protocol of the chosen engine (PostgreSQL, MySQL, MariaDB, SQL Server, Oracle)
Authentication
Database credentials over SSL/TLS, or IAM database authentication on supported engines
Change detection
Engine-native log-based CDC: MySQL/MariaDB binlog, PostgreSQL logical replication, SQL Server CDC; enabled through RDS parameter groups, with polling as a fallback
Capabilities

Rate limits
No API rate limits; throughput depends on instance class, storage IOPS, and connection limits

Ramp

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.
