Why teams connect Coupa and Iterable

Put revenue reality behind every campaign: Coupa and Iterable share the same customers, contacts, and billing status in real time, in both directions.

Coupa records the money — who pays, how much, and whether they are current; Iterable decides who hears from the business and what they hear. The two overlap wherever the same customers and contacts matter to both, and when that overlap is bridged by CSV exports or an overnight batch, campaigns target on stale billing data and finance works from lists marketing has already changed underneath it.

Stacksync syncs Invoices, Suppliers, Users, Accounts in Coupa with Campaigns, Templates, Lists, Catalogs in Iterable field by field, in real time, and in both directions. You decide which system owns which fields — finance keeps the revenue and payment truth, marketing keeps consent and engagement — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Push chart-of-accounts segments and cost centers from the ERP into Coupa Accounts so Requisitions and Invoices code to the right GL.
  • 02 Provision and update Users in Coupa from an HRIS or identity provider as employees join, change roles, or leave.
  • 03 Two-way sync User profiles and their custom data fields between Iterable and a Postgres database or CRM so attributes and subscription state stay aligned in both systems.
  • 04 Push warehouse or CRM audience segments into Iterable as Users via bulkUpdate (up to 1000 per call) and subscribe them to static Lists to drive campaigns.

Common sync patterns

Where Iterable captures new people: clean records flow to finance

Registrants, form fills, or leads created in Iterable create or update the matching customer or contact in Coupa, so billing and reporting start from accurate details without re-entry.

Where Coupa tracks lifecycle state: keep Iterable current

Trial, renewal, churn, or payment state from Coupa updates the contact in Iterable, so lifecycle campaigns and audience suppression run on current billing reality.

Consent and contact details stay aligned

Email, phone, address, and opt-out flags kept in either system stay consistent in the other, so every send and record honors the latest preferences.

What you can sync between Coupa and Iterable

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 Iterable objects How this pairing syncs
Users Employee and user accounts with roles and content groups; provisioned and updated from an HRIS or identity provider. Users User profiles keyed by email or userId with custom data fields; upserted via POST /api/users/update, read via GET /api/users/{email} or getByUserId, bulk-written via /api/users/bulkUpdate (up to 1000 users per call), and deleted or GDPR-forgotten. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping.
Expense Reports Employee expense reports and their lines; exported to AP or ERP for reimbursement and GL posting. Lists Static subscriber lists; read via GET /api/lists and /api/lists/getUsers, with users added or removed via /api/lists/subscribe and /api/lists/unsubscribe to control who receives a send. Expense Reports is specific to Coupa and Lists to Iterable — 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. Catalogs Named catalogs of items (products, content) used for personalization and recommendations; items upserted and read via /api/catalogs/{catalogName}/items. Requisitions is specific to Coupa and Catalogs to Iterable — 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. Commerce / Purchases Purchase and cart activity tracked via /api/commerce/trackPurchase and /api/commerce/updateCart, feeding revenue attribution and abandoned-cart journeys. Purchase Orders is specific to Coupa and Commerce / Purchases to Iterable — 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. Export data Historical user and event records pulled through the Export API (/api/export/data.json, data.csv, and userEvents) across data types like emailSend, emailOpen, emailClick, emailBounce, purchase, and customEvent. Invoices is specific to Coupa and Export data to Iterable — 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. Events Custom and system events tracked via /api/events/track and /api/events/trackBulk (up to 1000 events per call); a single user's event history is read via GET /api/events/{email}. Suppliers is specific to Coupa and Events to Iterable — each maps to any object or custom field on the other side.

How changes propagate between Coupa and Iterable

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 Iterable 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 written to Iterable through its API, with automatic retries and rate-limit backoff.

Iterable Coupa Sub-second propagation

DetectionIterable notifies Stacksync of record changes through webhook events. System Webhooks push email/SMS/push/in-app and custom events (send, open, click, bounce, complaint, unsubscribe) as JSON POSTs in near real time.

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.
  • Iterable: Limits are per endpoint and per project/key; exceeding one returns HTTP 429, so exponential backoff is advised. Event tracking allows far higher volume than metadata endpoints like campaigns/templates, and the Export API is throttled more tightly. Since Nov 10, 2025, passing the key in the query string or body is rate-limited more strictly than the Api-Key header.

How the Coupa and Iterable 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.

Iterable

Integration surface
Iterable REST API (JSON over HTTPS): Users, Events, Campaigns, Templates, Lists, Catalogs, and Commerce endpoints, plus a bulk Export API for historical data
Authentication
API key sent in the Api-Key HTTP header (also accepted as Api_Key; the name is case-insensitive). Keys are scoped by type - Server-side, JavaScript (Web SDK), or Mobile - with optional JWT-enabled keys. US projects use api.iterable.com; EU projects use api.eu.iterable.com.
Change detection
System Webhooks push email/SMS/push/in-app and custom events (send, open, click, bounce, complaint, unsubscribe) as JSON POSTs in near real time; historical backfill and incremental catch-up run through the Export API over a date range.
