Why teams connect Amazon Lightsail and Coupa

Work with Coupa's financial data straight from Amazon Lightsail: 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 Contracts, Expense Reports, Requisitions, Purchase Orders from Coupa into Databases, Schemas, Tables, Views in Amazon Lightsail and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Amazon Lightsail, and rows your code writes or updates flow back into Coupa with validation, so the finance system stays the system of record.

Common use cases

  • 01 Mirror Purchase Orders and their status into an operational Postgres database for spend reporting and three-way match analytics.
  • 02 Export approved Invoices and their lines from Coupa into an accounting/ERP system to drive the AP pay cycle and GL posting.
  • 03 Sync a Lightsail-hosted application database with a CRM so customer records match what the app stores.
  • 04 Push cleaned or enriched records from central systems back into the Lightsail database behind a small web app.

Common sync patterns

Internal tools without API plumbing

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

Write back safely

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

React to financial events

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

What you can sync between Amazon Lightsail and Coupa

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 Lightsail objects Coupa objects How this pairing syncs
Views Query-backed read-only sources. Purchase Orders PO headers and lines; synced two-way with ERPs so orders raised in Coupa flow to the ledger and status updates flow back on the /purchase_orders resource. Views is specific to Amazon Lightsail and Purchase Orders to Coupa — each maps to any object or custom field on the other side.
Users and Grants Database accounts used to give the sync connection scoped access. Invoices Supplier/AP invoices with lines and approval status; polled out to accounting and ERP systems for the pay cycle, or created through the API. Users and Grants is specific to Amazon Lightsail and Invoices to Coupa — each maps to any object or custom field on the other side.
Managed Databases Lightsail-hosted MySQL or PostgreSQL instances that a sync connects to as standard databases. Suppliers Supplier master records; kept aligned with an ERP vendor master and onboarding tools, synced two-way on the /suppliers resource. Managed Databases is specific to Amazon Lightsail and Suppliers to Coupa — each maps to any object or custom field on the other side.
Databases Logical databases on the instance that scope a connection. Users Employee and user accounts with roles and content groups; provisioned and updated from an HRIS or identity provider. Databases is specific to Amazon Lightsail and Users to Coupa — each maps to any object or custom field on the other side.
Schemas Namespaces used when selecting tables to sync. Accounts Chart-of-accounts segments and GL codes; usually mastered in the ERP and written into Coupa so requisitions and invoices code correctly. Schemas is specific to Amazon Lightsail and Accounts to Coupa — each maps to any object or custom field on the other side.
Tables Relational tables read from and written to at row level. Contracts Supplier contract records with terms and dates; read out for reporting or created from a CLM system. Tables is specific to Amazon Lightsail and Contracts to Coupa — each maps to any object or custom field on the other side.

How changes propagate between Amazon Lightsail and Coupa

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 Lightsail Coupa Interval-based propagation

DetectionStacksync polls Amazon Lightsail for changes on an incremental schedule, reading only records changed since the previous pass. Polling on timestamp or key columns.

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

Coupa Amazon Lightsail Interval-based propagation

DetectionStacksync polls Coupa for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at and created-at filters (e.g.

DeliveryEach detected change is applied to Amazon Lightsail as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Amazon Lightsail: No API-style rate limits; capacity is fixed by the chosen Lightsail bundle.
  • Coupa: Coupa does not publish explicit rate limits or expose X-RateLimit/Retry-After headers; integrations page 50 records at a time and back off on 429/503 responses.

How the Amazon Lightsail and Coupa connectors work

Amazon Lightsail

Integration surface
MySQL or PostgreSQL wire protocol (SQL) to the managed database endpoint
Authentication
Database credentials; public endpoint access must be enabled or a tunnel used
Change detection
Polling on timestamp or key columns; log-based CDC depends on engine parameter access, which is more limited than on full RDS

No API-style rate limits; capacity is fixed by the chosen Lightsail bundle

Coupa

Integration surface
REST Core API (JSON or XML)
Authentication
OAuth 2.0 / OIDC via the client-credentials grant; scopes take the service.object.right form (e.g. core.accounting.read, core.accounting.write). Legacy API keys are being retired (no new keys since R34; API-key auth unsupported from R36). Access tokens last 24 hours.
Change detection
Polling on updated-at and created-at filters (e.g. updated-at[gt]=<timestamp>); Coupa has no native webhook subscriptions, though admins can configure outbound Call Out / external notifications.
