Use the Sequenzy community node for n8n to trigger workflows from Sequenzy outbound events, and to send form submissions, billing events, spreadsheet rows, and other workflow data into Sequenzy. The package is published as n8n-nodes-sequenzy. The source is available on GitHub.

​
Install the Community Node

Install Sequenzy from n8n’s Community Nodes screen:
  1. In n8n, go to Settings → Community Nodes.
  2. Select Install.
  3. Enter n8n-nodes-sequenzy.
  4. Confirm the install and restart n8n if your instance asks you to.
  5. Add a Sequenzy node to a workflow.
For self-hosted deployments, you can also install the package with npm in the n8n environment:
Install community nodes only in n8n workspaces where your team allows community packages. Sequenzy does not require any manual approval outside your n8n instance.

​
Authentication

The n8n node uses Sequenzy API key authentication.
  1. In Sequenzy, go to Settings → API Keys & SMTP.
  2. Create or copy a workspace API key. New workspace keys start with seq_live_; legacy ek_ keys remain supported.
  3. In n8n, create a credential of type Sequenzy API.
  4. Paste the API key and save the credential.
  5. Select that credential on each Sequenzy node.
By default, the credential sends requests to https://api.sequenzy.com/api/v1 with:

​
Supported Operations

The package includes a trigger node and an action node.

​
Trigger Events

Use Sequenzy Trigger when Sequenzy should start an n8n workflow. Choose one or more outbound events; the default is New Subscriber (subscriber.created). The trigger creates an ordinary Sequenzy outbound webhook endpoint using n8n’s production webhook URL, stores the one-time HMAC signing secret in the workflow’s node static data, and verifies X-Sequenzy-Signature before starting the workflow. Common trigger events:
  • subscriber.created for new subscribers
  • campaign.sent when an email or SMS campaign reaches its final sent state
  • email.replied for inbound replies
  • subscriber.unsubscribed for opt-outs
  • sequence.finished and sequence.failed for lifecycle automation
The trigger outputs the full Sequenzy event envelope, including id, type, created_at, metric, and data. Delivery uses the same durable outbound-webhook pipeline as every other Sequenzy endpoint: each request is HMAC-signed and failed deliveries are tried up to 16 times across seven days. Per-message events such as email.opened, email.clicked, and email.sent can start one n8n execution per recipient, so select them only when the workflow is sized for that volume.

​
Subscriber Fields

Create or Update supports:
  • Email or External ID
  • First name
  • Last name
  • Tags as a comma-separated list
  • Custom attributes as key-value pairs
  • Enroll in Sequences
Get and Delete accept either Email or External ID.

​
Tag Fields

Add and Remove require a tag plus either Email or External ID. Add also accepts first and last name values for cases where Sequenzy needs to create the subscriber before applying the tag.

​
Event Fields

Trigger requires an event name plus either Email or External ID. You can also send first name, last name, and event properties as key-value pairs. Use event names that match your Sequenzy automations, such as signup.completed, trial_started, checkout.completed, or subscription.canceled.

​
Example Workflows

​
Webhook or Form to Sequenzy Subscriber

Use this when a custom form, landing page, or internal app can POST to n8n.
Map the incoming email to the Sequenzy Email field. Put form answers you want to segment on into Custom Attributes, and add tags such as lead, demo-request, or newsletter.

​
Typeform, Tally, or Jotform to Sequenzy Subscriber

Use the native app node when your n8n instance has one, or use the app’s webhook feature with n8n’s Webhook node.
Recommended mapping:

​
Stripe Event to Sequenzy Event

Use this when payment activity should trigger Sequenzy automations.
Recommended events:
  • stripe.checkout_completed
  • stripe.subscription_created
  • stripe.payment_failed
  • stripe.subscription_canceled
Map the customer email or your own customer ID, then pass Stripe values such as price ID, product name, subscription status, amount, currency, or trial end as event properties.

​
Google Sheets Row to Sequenzy Subscriber

Use this when a spreadsheet is the source of leads or imported contacts.
Map the email column to Email. Map name columns to First Name and Last Name. Map other columns such as company, role, plan, or source to Custom Attributes.

​
Sequenzy Event to n8n Workflow

Use this when Sequenzy should notify n8n about email, campaign, subscriber, or sequence lifecycle events.
Add a Sequenzy Trigger node, select your Sequenzy API credential, and choose the events your workflow needs. n8n must provide a production HTTPS webhook URL when the workflow is activated. The API key must have account read and webhook read, write, and delete permissions (account:read, webhooks:read, webhooks:write, and webhooks:delete). Account read lets n8n validate the shared Sequenzy credential; the webhook permissions let the node create, reconcile, and clean up its managed outbound webhook endpoint.

​
Manual Fallback: Sequenzy Outbound Webhook to n8n Webhook Node

Use this if you prefer n8n’s generic Webhook node or cannot install community trigger nodes.
Create an n8n Webhook node first and copy its production URL. Then create a Sequenzy outbound webhook endpoint pointing to that URL. Subscribe to the Sequenzy events your workflow needs, such as campaign.sent, email.replied, subscriber.unsubscribed, sequence.finished, or email.clicked. See Outbound Webhooks for payloads, signatures, retries, and delivery behavior.

​
Limitations

  • The Sequenzy Trigger manages one Sequenzy outbound webhook endpoint per active workflow. Deactivating the workflow deletes that managed endpoint.
  • The node uses API key authentication. OAuth is not supported.
  • The node runs once per incoming n8n item. For high-volume imports, prefer the Sequenzy bulk API endpoints or batch your workflow carefully.
  • Custom attributes and event properties are configured as key-value pairs in the node UI. Use a Set or Code node before Sequenzy if you need to normalize complex source data.
  • Subscriber lookup returns data only when a matching subscriber is found. Build your workflow so the not-found path is handled explicitly.

​
Troubleshooting

​
Test Against a Local Sequenzy API

The node uses https://api.sequenzy.com/api/v1 by default. When developing the node locally, start n8n with SEQUENZY_API_BASE_URL set to the local API:
Restart n8n after changing the value. If the variable is unset or blank, the node uses the production Sequenzy API. This override is for local or self-hosted n8n because n8n Cloud does not expose custom environment variables to community nodes. To test the trigger locally, expose n8n’s port with ngrok:
Keep ngrok running, copy its HTTPS forwarding URL, and restart n8n:

​
Credential Test Fails

Confirm the workspace API key starts with seq_live_ (or the legacy ek_ prefix), has not been deleted, and was pasted into the Sequenzy API credential without extra spaces.

​
Subscriber Was Not Created

Confirm the workflow provides either Email or External ID. For new subscribers, Email is recommended because Sequenzy needs an address before it can send email.

​
Automation Did Not Start

Confirm the Sequenzy automation is published and listens for the exact event name or tag used by the n8n node. Event names and tag names are case-sensitive.

​
Outbound Webhook Did Not Reach n8n

For Sequenzy Trigger, confirm the workflow is active, n8n exposes a public HTTPS production URL, and the credential has account read plus webhook read, write, and delete permissions. Deactivate and reactivate the workflow to recreate an endpoint whose one-time signing secret is missing. Then check webhook delivery status in Sequenzy and execution history in n8n. For the manual fallback, use the production URL from the n8n Webhook node, not its temporary test URL.
