Why teams connect Coupa and Postgres Heroku

Work with Coupa's financial data straight from Postgres Heroku: 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 Users, Accounts, Contracts, Expense Reports from Coupa into Follower Databases, Tables, Views, Materialized Views in Postgres Heroku and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Postgres Heroku, 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 Reflect billing and subscription records into the app database so product logic reads local rows
  • 04 Expose CRM objects as Postgres tables the Heroku application can query and join directly

Common sync patterns

React to financial events

Changes in Coupa appear in Postgres Heroku 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 Coupa live in Postgres Heroku 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 Postgres Heroku; Stacksync handles the API calls, rate limits, and retries against Coupa.

What you can sync between Coupa and Postgres Heroku

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 Postgres Heroku objects How this pairing syncs
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. Tables Standard Postgres tables; the primary two-way sync target for app data. Purchase Orders is specific to Coupa and Tables to Postgres Heroku — 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. Views Read-side projections exposed to outbound syncs. Invoices is specific to Coupa and Views to Postgres Heroku — 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. Materialized Views Precomputed result sets synced outward on refresh. Suppliers is specific to Coupa and Materialized Views to Postgres Heroku — each maps to any object or custom field on the other side.
Users Employee and user accounts with roles and content groups; provisioned and updated from an HRIS or identity provider. Schemas Namespaces that scope which tables a sync reads and writes. Users is specific to Coupa and Schemas to Postgres Heroku — each maps to any object or custom field on the other side.
Accounts Chart-of-accounts segments and GL codes; usually mastered in the ERP and written into Coupa so requisitions and invoices code correctly. Primary and Unique Keys Match keys for idempotent upserts from connected systems. Accounts is specific to Coupa and Primary and Unique Keys to Postgres Heroku — each maps to any object or custom field on the other side.
Contracts Supplier contract records with terms and dates; read out for reporting or created from a CLM system. JSONB Columns Semi-structured payloads for nested SaaS objects and metadata. Contracts is specific to Coupa and JSONB Columns to Postgres Heroku — each maps to any object or custom field on the other side.

How changes propagate between Coupa and Postgres Heroku

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 Postgres Heroku 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 Postgres Heroku as a row-level write, with types converted between the two schemas.

Postgres Heroku Coupa Interval-based propagation

DetectionStacksync polls Postgres Heroku for changes on an incremental schedule, reading only records changed since the previous pass. Trigger-based capture or polling in most configurations.

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.
  • Postgres Heroku: No API rate limits; connection counts and performance are bounded by the Heroku Postgres plan.

How the Coupa and Postgres Heroku 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.

Rate limits
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.

Postgres Heroku

Integration surface
SQL wire protocol (standard PostgreSQL)
