Why teams connect Iterable and Streak CRM

Keep the people you sell to and the people you market to in one shared view: Streak CRM and Iterable sync contacts, accounts, and engagement in real time, in both directions.

Streak CRM owns the customer relationship and the pipeline; Iterable runs the campaigns, audiences, and outreach that fill it. The two overlap on the same people and companies — a lead in one system is a subscriber, a segment member, an event registrant, or an ad audience in the other. When that overlap is bridged by CSV exports or a nightly job, sales works from lists that no longer match reality and marketing keeps targeting people whose status has already moved on.

Stacksync syncs Contacts, Organizations, Tasks, Email threads in Streak CRM with Campaigns, Templates, Lists, Catalogs in Iterable field by field, in real time, and in both directions. You decide which system owns which fields — Streak CRM can own account and opportunity status while Iterable owns engagement and campaign membership — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Push deals and contacts into a warehouse to report on pipeline alongside product and billing data
  • 02 Hand off closed-won boxes to billing or fulfillment systems and sync status back into the pipeline
  • 03 Stream Iterable System Webhook events into a database in near real time so opens, clicks, bounces, and unsubscribes land alongside CRM contact records.
  • 04 Write list subscribe/unsubscribe changes from a CRM back into Iterable Lists so suppression and opt-in state stay current before the next send.

Common sync patterns

Where Iterable generates leads: hand-off without re-keying

New leads or responders captured in Iterable flow into Streak CRM assigned and deduplicated, so nothing sits in a marketing list waiting for someone to export it.

New and updated people stay in step

When a contact or lead is created or edited in either system, the matching record appears or updates in the other, so campaigns reach real people and reps see who is already being marketed to.

Where Iterable captures engagement: activity lands on the record

Opens, clicks, form fills, event attendance, or ad responses recorded in Iterable post back to the contact or account in Streak CRM, so reps see interest before they reach out.

What you can sync between Iterable and Streak CRM

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.

Iterable objects Streak CRM objects How this pairing syncs
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. Stages Pipeline steps whose transitions are the usual trigger for downstream syncs. Lists is specific to Iterable and Stages to Streak CRM — each maps to any object or custom field on the other side.
Catalogs Named catalogs of items (products, content) used for personalization and recommendations; items upserted and read via /api/catalogs/{catalogName}/items. Contacts People linked to boxes, synced with marketing and support tools. Catalogs is specific to Iterable and Contacts to Streak CRM — each maps to any object or custom field on the other side.
Commerce / Purchases Purchase and cart activity tracked via /api/commerce/trackPurchase and /api/commerce/updateCart, feeding revenue attribution and abandoned-cart journeys. Organizations Company records associated with contacts and boxes. Commerce / Purchases is specific to Iterable and Organizations to Streak CRM — each maps to any object or custom field on the other side.
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. Tasks To-dos attached to boxes for follow-up tracking. Export data is specific to Iterable and Tasks to Streak CRM — each maps to any object or custom field on the other side.
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. Email threads Gmail threads linked to boxes, since the CRM lives inside the inbox. Users is specific to Iterable and Email threads to Streak CRM — each maps to any object or custom field on the other side.
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}. Custom fields Per-pipeline field definitions that determine what data a box can hold. Events is specific to Iterable and Custom fields to Streak CRM — each maps to any object or custom field on the other side.

How changes propagate between Iterable and Streak CRM

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.

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

Streak CRM Iterable Interval-based propagation

DetectionStacksync polls Streak CRM for changes on an incremental schedule, reading only records changed since the previous pass. Polling against pipeline, box, and contact endpoints.

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

Rate-limit considerations

  • 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.
  • Streak CRM: Subject to the platform's API rate limits; quotas are not prominently published.

How the Iterable and Streak CRM connectors work

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.
