How to Connect Iterable to n8n

Integrating your marketing stack requires establishing secure, authenticated communications between your data runner and the destination marketing engine. To connect Iterable's API to your n8n workflows, you must capture credential configurations that authorize REST calls. This foundation allows you to manage user subscriptions, trigger dynamic templates, and synchronize external events without manual work.

1. Generate a valid API key within your Iterable project dashboard. Navigate to Integrations and select API Keys from the sub-menu. Click the button to create a new API key, providing a recognizable name. Select the exact permission scopes your automation requires. Minimal privileges are recommended, such as setting write scopes specifically for users or events.
2. Configure a custom connection within your n8n instance. Add an HTTP Request Node to your workflow canvas. Under the Authentication section, set the dropdown selection to Header Auth. For the key property, define the header as Api-Key. For the value field, copy and paste the API key generated in the previous step. Save the credentials inside n8n to reference them across other workflows.
3. Test the active connection. Add a simple GET request within the HTTP Request Node pointing to the user profile lookup endpoint: https://api.iterable.com/api/users/{email}, replacing the placeholder with a known subscriber email address. Click the test execution button to verify that a successful HTTP 200 payload returns from the server with corresponding user fields.

Workflow 1: Syncing HubSpot CRM with Iterable Profiles via n8n

Synchronizing operational sales data with growth marketing campaigns ensures communication stays aligned with customer context. When sales development representatives update lead status or lifecycle stages in a CRM like HubSpot, those segments must immediately reflect inside your active email engines. This avoids sending top-of-funnel marketing emails to accounts already in late-stage sales discussions.

How It Works

This automated bridge initiates with a HubSpot Webhook Trigger node. This trigger listens specifically for lead lifecycle changes or deal movements. When an event fires, the payload captures contact properties, including email address, company name, and current lifecycle status. The data immediately processes through an Edit Fields node to filter out empty spaces and format key properties into standard JSON objects. Next, an If Node checks whether the contact's email is present and valid.

Once validated, the payload connects to an HTTP Request Node configured to make a POST call to https://api.iterable.com/api/users/update. This node uses the predefined Header Auth credentials. In the body parameters, the target email is mapped alongside custom fields in the dataFields object, updating parameters such as lifecycleStage, ownerEmail, and activeDealValue. Iterable parses this array, updating existing attributes or establishing a fresh contact record if the identifier is unrecognized.

Real-World Example

Consider a sales cycle where a prospect shifts from "Marketing Qualified Lead" (MQL) to "Sales Qualified Lead" (SQL) within your pipeline. The HubSpot contact webhook sends a JSON notification containing this update. The workflow captures this specific contact identifier:

{
  "email": "[email protected]",
  "lifecycleStage": "salesqualifiedlead",
  "salesRep": "[email protected]"
}

The n8n runner processes the parameters, injecting these values into an Iterable profile update call. Once completed, Iterable places the user in an automated sales-assist journey while suppressing generic company-wide promotional newsletters. This automated sync eliminates discrepancies between sales calls and active digital outreach campaigns.

Pro Tips

To avoid hitting HubSpot and Iterable API limits, structure your n8n routing to ignore passive field updates. Setting up your CRM webhooks to fire only when specific monitored fields change prevents redundant executions. This optimization maintains high throughput while protecting your platform API limits.

Workflow 2: Triggering Iterable Campaigns via Stripe Events with n8n

Transactional emails demand instantaneous execution when subscription billing events occur. Payment issues, invoice creation, and subscription renewals directly affect your bottom-line retention. Handling these events by routing billing statuses directly into customized email alerts keeps customers informed and reduces passive churn.

How It Works

This pipeline connects a Stripe Webhook Trigger node directly with campaign-triggering protocols. The Stripe node intercepts payment events like invoice.payment_failed or customer.subscription.deleted. Once received, the incoming customer ID is sent to a secondary Stripe Node to retrieve the customer's billing email and account details. An Edit Fields node then parses the subscription tier, outstanding balance, and localized currency settings.

With billing data compiled, an HTTP Request Node initiates a POST request targeting the Iterable campaign execution path: https://api.iterable.com/api/campaigns/trigger. The request body contains the target campaign ID, the user's email address, and an object of dataFields containing custom billing variables. This payload injects localized outstanding amounts and custom account management links directly into the designated email template, delivering the update in real time.

Real-World Example

A customer's subscription card fails to clear during regular monthly processing. Stripe emits an invoice.payment_failed hook payload. n8n intercepts the invoice ID, extracts the active billing email, and references the current failed invoice amount of $49.00. The workflow automatically sends a trigger command to Iterable campaign ID 50281 with dynamic parameters:

{
  "campaignId": 50281,
  "recipientEmail": "[email protected]",
  "dataFields": {
    "failedAmount": "$49.00",
    "retryDate": "2026-08-28",
    "updateBillingUrl": "https://billing.domain.com/update"
  }
}

Iterable processes the variables and immediately dispatches a specialized billing warning containing their personal checkout update portal. This configuration ensures no lag time occurs between a transaction failure and customer notifications, boosting payment recovery rates.

Workflow 3: Enriching Iterable Profiles with Database Records in n8n

Marketing teams often face limitations when user telemetry and product interaction data are locked inside internal application databases. To build segment criteria based on active application usage, teams require access to structured backend telemetry. By pulling SQL records and uploading them directly to user profiles, you enable behavior-based targeting.

How It Works

This data enrichment system runs on a scheduled cadence using an n8n Schedule Trigger node configured to execute daily during low-traffic overnight hours. The workflow proceeds immediately to a PostgreSQL or MySQL Node, which runs an optimized analytics query. This query extracts aggregated active days, files created, and subscription statuses for all active users over the past 24 hours.

Because querying thousands of databases produces extensive datasets, the n8n runner uses a Split In Batches node to divide records into batches of 1,000 items. Each batch feeds directly into an HTTP Request Node making a POST request to the bulk update endpoint: https://api.iterable.com/api/users/bulkUpdate. This payload sends a JSON array of users and dataFields, which updates thousands of matching profiles in a single API round-trip.

Real-World Example

An application team tracks customer interaction levels inside a database. A SQL query isolates records showing a user created over 50 documents, indicating power-user status. The n8n automation parses the query's outputs and builds a unified payload:

{
  "users": [
    {
      "email": "[email protected]",
      "dataFields": {
        "documentsCreated": 52,
        "tierStatus": "Power User"
      }
    },
    {
      "email": "[email protected]",
      "dataFields": {
        "documentsCreated": 60,
        "tierStatus": "Power User"
      }
    }
  ]
}

The bulk update updates user records in Iterable overnight, shifting them into a VIP messaging segment. This allows your growth team to send targeted invitations for premium training webinars or exclusive feature feedback panels.

Pro Tips

When running large database syncs, always execute updates using bulk endpoints rather than running loop updates on single profiles. Individual calls exhaust API limits quickly and increase workflow memory footprint. Batching profile updates keeps execution flows brief and predictable.

Workflow 4: Syncing Offline Purchases to the Iterable Track API using n8n

Many legacy enterprise applications register sales, retail point-of-sale activities, or physical event check-ins as isolated data silos. Bridging these physical touchpoints into your online campaigns ensures your marketing campaigns reflect the customer's complete purchase history, even when transactions happen offline.

How It Works

This automated flow begins by checking target directories using an AWS S3 Node or SFTP Node on an interval schedule. When it detects a new purchase registry CSV upload, the workflow retrieves the document as binary data. This data passes directly to an Extract From File (CSV) Node, which parses rows of comma-separated columns into structured JSON elements.

After transforming the spreadsheet data into JSON arrays, an Edit Fields node maps values such as transactional IDs, purchase locations, items bought, and customer emails. An HTTP Request Node then routes individual events to the Iterable Track endpoint: https://api.iterable.com/api/events/track. This maps purchase records directly to customer timelines, triggering automated post-purchase workflows based on physical store visits.

Real-World Example

An physical store locations manager uploads transactional sales registers to an SFTP server every evening at close. n8n fetches this CSV file, parses the data, and identifies a customer who purchased a premium jacket in-store. The parsed transaction records are sent to the track API:

{
  "email": "[email protected]",
  "eventName": "offlinePurchase",
  "dataFields": {
    "storeLocation": "Downtown Chicago",
    "itemCategory": "Apparel",
    "totalValue": 189.00
  }
}

Iterable records the offline event, instantly initiating a post-purchase series that sends garment-care instructions and related accessory discounts. This matches your physical footprint with digital personalization.

Workflow 5: Syncing Iterable Bounce and Unsubscribe Events to Postgres in n8n

Maintaining high deliverability rates depends on tracking email bounce and opt-out rates across all active channels. Failing to capture unsubscribes or hard bounces inside internal databases can lead to compliance violations or poor sender reputation if other systems continue sending outreach emails to inactive addresses.

How It Works

This automated loop starts with an n8n Webhook Trigger node that exposes a dedicated web entry link to receive outgoing events from Iterable. Inside the Iterable system dashboard, you configure a system webhook to stream events like emailBounce or userUnsubscribe directly to your n8n entry URL. When an email bounces, a payload containing recipient information, bounce classification, and timestamp details is instantly transmitted to n8n.

Once received, the webhook payload goes through a Switch Node to analyze the payload's event type. If it identifies an email hard bounce or opt-out event, the data routes to a Postgres or MySQL Node. The database node executes an SQL INSERT or UPDATE statement to update the recipient's status to inactive or adds them to an internal database suppression list, protecting your outbound messaging channels from sending to invalid mailboxes.

Real-World Example

An email to a contact hard bounces due to a closed or invalid account. Iterable detects this status change and sends an event packet to the n8n endpoint. The workflow parses the event structure:

{
  "email": "[email protected]",
  "eventType": "emailBounce",
  "bounceClass": "hardBounce",
  "timestamp": 1787654400
}

The workflow evaluates the hard bounce status and inserts the record directly into your internal global suppression database table. Any future sales outreach, billing notices, or secondary platform updates query this suppression list first, protecting your server reputation.
