Why teams connect Coupa and Dynamo DB
Work with Coupa'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 Accounts, Contracts, Expense Reports, Requisitions from Coupa into DynamoDB Streams, Global Tables, Tables, Items 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 Coupa with validation, so the finance system stays the system of record.
Common use cases
- 01 Provision and update Users in Coupa from an HRIS or identity provider as employees join, change roles, or leave.
- 02 Mirror Purchase Orders and their status into an operational Postgres database for spend reporting and three-way match analytics.
- 03 Consolidate multi-region Global Tables data into a single reporting store.
- 04 Replace ad-hoc export scripts with continuous sync driven by DynamoDB Streams.
Common sync patterns
Query finance data like any other data
Customers, invoices, and payments from Coupa 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 Coupa.
Write back safely
Updates written to the synced tables in Dynamo DB propagate into Coupa, so automations can create or correct finance records without custom integration code.
What you can sync between Coupa and Dynamo DB
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.
| Coupa objects | Dynamo DB objects | How this pairing syncs | |
|---|---|---|---|
| Contracts Supplier contract records with terms and dates; read out for reporting or created from a CLM system. | DynamoDB Streams Ordered item-level change records consumed for incremental sync. | Contracts is specific to Coupa and DynamoDB Streams to Dynamo DB — each maps to any object or custom field on the other side. | |
| Expense Reports Employee expense reports and their lines; exported to AP or ERP for reimbursement and GL posting. | Global Tables Multi-region replicas relevant when syncs must read from a specific region. | Expense Reports is specific to Coupa and Global Tables to Dynamo DB — each maps to any object or custom field on the other side. | |
| Requisitions Employee purchase requests with lines and approval chains; read out to warehouses, or created via the API from upstream intake tools. | Tables The top-level containers a sync targets; each table is addressed independently. | Requisitions is specific to Coupa and Tables to Dynamo DB — each maps to any object or custom field on the other side. | |
| 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. | Items Schemaless records keyed by partition (and optional sort) key, mapped to rows or SaaS objects in syncs. | Purchase Orders is specific to Coupa and Items to Dynamo DB — each maps to any object or custom field on the other side. | |
| 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. | Attributes Per-item fields, including nested maps and lists, flattened or mapped during sync. | Invoices is specific to Coupa and Attributes to Dynamo DB — each maps to any object or custom field on the other side. | |
| Suppliers Supplier master records; kept aligned with an ERP vendor master and onboarding tools, synced two-way on the /suppliers resource. | Partition and Sort Keys The primary key pair used as the match key for bi-directional sync. | Suppliers is specific to Coupa and Partition and Sort Keys to Dynamo DB — each maps to any object or custom field on the other side. |
How changes propagate between Coupa and Dynamo DB
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.
Coupa Dynamo DB 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 Dynamo DB as a row-level write, with types converted between the two schemas.
Dynamo DB Coupa 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 Coupa through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- 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.
- Dynamo DB: Throughput is governed by the table's provisioned or on-demand capacity mode.

How the Coupa and Dynamo DB connectors work
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.

-
Change detection on Coupa: 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.
