ConvertKit Trigger

Start workflow from ConvertKit events

Overview

Starts a workflow when ConvertKit sends a webhook notification for subscriber events such as form subscriptions, tag changes, link clicks, sequence completions, product purchases, and subscriber state changes. Receives POST requests from ConvertKit’s automation hooks and normalizes the payload for downstream processing.

Parameters

Parameter	Type	Required	Default	Description
Event	options	Yes	—	The ConvertKit event that triggers the workflow.
				Options: formSubscribe, linkClick, productPurchase, purchaseCreate, courseComplete (Sequence Complete), courseSubscribe (Sequence Subscribe), subscriberActivate, subscriberUnsubscribe, tagAdd, tagRemove
Form ID	string	Yes	—	The ID of the form to monitor for subscriptions. (shown when Event is formSubscribe)
Sequence ID	string	Yes	—	The ID of the sequence (course) to monitor. (shown when Event is courseSubscribe, courseComplete)
Initiating Link	string	Yes	—	The URL of the link to monitor for clicks. (shown when Event is linkClick)
Product ID	string	Yes	—	The ID of the product to monitor for purchases. (shown when Event is productPurchase)
Tag ID	string	Yes	—	The ID of the tag to monitor for additions or removals. (shown when Event is tagAdd, tagRemove)

The Purchase Created, Subscriber Activated, and Subscriber Unsubscribe events need no extra parameter — selecting the event is enough.

Output Data

Each delivery from ConvertKit produces one output item. The webhook payload is copied onto the item unchanged, and three fields are added:

• _trigger — always convertkit_webhook
• _timestamp — ISO 8601 timestamp of when the request arrived
• _webhookEvent — the event name reported by ConvertKit, taken from the payload’s event field

Subscriber events carry a subscriber object with id, first_name, email_address, state, created_at, and a fields object holding the subscriber’s custom fields.

Reference the payload downstream by expression, e.g. {{ $json.subscriber.email_address }}.

Usage Examples

• trigger workflow when someone subscribes to a ConvertKit form
• start workflow when a subscriber clicks a link
• run automation when a ConvertKit tag is added to a subscriber
• process ConvertKit purchase events in real time
• react when a subscriber completes a ConvertKit sequence

Example Configuration

Fire when someone subscribes through a specific form:

{
  "id": "convertkit-trigger",
  "name": "ConvertKit Form Subscribe",
  "type": "convertkit_trigger",
  "parameters": {
    "event": "formSubscribe",
    "formId": "123456"
  }
}

Fire when a subscriber finishes a sequence:

{
  "id": "convertkit-trigger",
  "name": "ConvertKit Course Complete",
  "type": "convertkit_trigger",
  "parameters": {
    "event": "courseComplete",
    "courseId": "789012"
  }
}

Fire when a subscriber clicks a tracked link:

{
  "id": "convertkit-trigger",
  "name": "ConvertKit Link Click",
  "type": "convertkit_trigger",
  "parameters": {
    "event": "linkClick",
    "link": "https://example.com/special-offer"
  }
}

Fire when a specific product is purchased:

{
  "id": "convertkit-trigger",
  "name": "ConvertKit Product Purchase",
  "type": "convertkit_trigger",
  "parameters": {
    "event": "productPurchase",
    "productId": "345678"
  }
}

Fire when a tag is added to a subscriber:

{
  "id": "convertkit-trigger",
  "name": "ConvertKit Tag Add",
  "type": "convertkit_trigger",
  "parameters": {
    "event": "tagAdd",
    "tagId": "901234"
  }
}

Fire on subscriber activation — no extra parameter needed:

{
  "id": "convertkit-trigger",
  "name": "ConvertKit Subscriber Activate",
  "type": "convertkit_trigger",
  "parameters": {
    "event": "subscriberActivate"
  }
}

Track unsubscribes for list management:

{
  "id": "subscriber-unsubscribe-trigger",
  "name": "Subscriber Unsubscribed",
  "type": "convertkit_trigger",
  "parameters": {
    "event": "subscriberUnsubscribe"
  }
}

Trigger Behavior

• Activation: When the workflow is activated, a webhook endpoint is registered with the service.
• Deactivation: The webhook is automatically unregistered when the workflow is deactivated.
• Payload: The incoming webhook payload is parsed and output as workflow items.
• Verification: Supports signature verification where applicable.

Tips

Entry point that fires when ConvertKit sends an automation hook event. Configure which event to listen for (form subscribe, tag add/remove, link click, purchase, sequence complete/subscribe, subscriber activate/unsubscribe) and optionally filter by a specific form, tag, sequence, product, or link. Outputs the subscriber and event data for downstream processing.
