Why teams connect Hyperline and Iterable

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

Hyperline 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 Customers, Subscriptions, Products / prices, Invoices in Hyperline with Catalogs, Commerce / Purchases, Export data, Users 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 Create billing customers automatically when new accounts appear in the CRM or product database.
  • 02 Sync Hyperline customers and subscription status into a CRM so sales and success teams see billing state on the account record.
  • 03 Track product and revenue Events (custom events, trackPurchase, updateCart) into Iterable from an app or database so journeys trigger on live behavior.
  • 04 Export Iterable engagement data (emailSend, emailOpen, emailClick, emailBounce, purchase) into a warehouse for deliverability and campaign reporting.

Common sync patterns

Where Hyperline tracks lifecycle state: keep Iterable current

Trial, renewal, churn, or payment state from Hyperline 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.

Revenue and billing signals reach the audience

Plan tier, spend, or payment status from Hyperline lands on the matching record in Iterable, so segments and targeting reflect who actually pays and how much.

What you can sync between Hyperline 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.

Hyperline objects Iterable objects How this pairing syncs
Subscriptions Active plans and their lifecycle state, synced to show billing status elsewhere. 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. Subscriptions is specific to Hyperline and Lists to Iterable — each maps to any object or custom field on the other side.
Products / prices The catalog of products and price configurations referenced by subscriptions. Catalogs Named catalogs of items (products, content) used for personalization and recommendations; items upserted and read via /api/catalogs/{catalogName}/items. Products / prices is specific to Hyperline and Catalogs to Iterable — each maps to any object or custom field on the other side.
Invoices Issued billing documents synced into accounting and reporting systems. Commerce / Purchases Purchase and cart activity tracked via /api/commerce/trackPurchase and /api/commerce/updateCart, feeding revenue attribution and abandoned-cart journeys. Invoices is specific to Hyperline and Commerce / Purchases to Iterable — each maps to any object or custom field on the other side.
Payments Settlement records used to reconcile revenue against invoices. 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. Payments is specific to Hyperline and Export data to Iterable — each maps to any object or custom field on the other side.
Billable events Metered consumption events ingested to drive usage-based charges. 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. Billable events is specific to Hyperline and Users to Iterable — each maps to any object or custom field on the other side.
Credit notes Adjustments and refunds synced for accurate revenue reporting. 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}. Credit notes is specific to Hyperline and Events to Iterable — each maps to any object or custom field on the other side.

How changes propagate between Hyperline 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.

Hyperline Iterable Sub-second propagation

DetectionHyperline notifies Stacksync of record changes through webhook events. Webhooks for billing events, with polling as a fallback.

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

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

Rate-limit considerations

  • Hyperline: Subject to the platform's API rate limits.
  • 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.
