Visitor Kinds

Visitor Kind	Description
`contact`	Identified visitor with contact information (email, name)
`company`	Anonymous visitor identified only at company level

The company and contact objects are only included when that data is available. Anonymous visitors may only have company-level identification.

Payload Data: AI Search Detection

The visitor.identified webhook automatically includes AI search detection:

AI Engine	Detection Method
ChatGPT	UTM source parameter contains “chatgpt”
Perplexity AI	Referrer URL contains “perplexity.ai”
Google Gemini	Referrer URL contains “gemini.google.com” or “bard.google.com”
Claude AI	Referrer URL contains “claude.ai”
Phind	Referrer URL contains “phind.com”
You.com	Referrer URL contains “you.com”
Bing Chat	Referrer URL contains “bing.com/chat”
Poe	Referrer URL contains “poe.com”

ChatGPT is detected via UTM source parameter (e.g., ?utm_source=chatgpt) since ChatGPT doesn’t send a referrer header.

Payload Data: Traffic Classification

All traffic is classified into categories in the ref_medium field:

Category	Description
`ai_search`	AI search engines (ChatGPT, Perplexity, etc.)
`paid_search`	Paid advertising (UTM medium contains “cpc”, “ppc”, or “paid”)
`search`	Organic search (Google, Bing, DuckDuckGo, etc.)
`social`	Social media (LinkedIn, Twitter/X, Facebook, Reddit, etc.)
`email`	Email campaigns (UTM medium is “email” or “newsletter”)
`referral`	Other website referrals
`direct`	Direct traffic (no referrer)

Payload Data: CMS Content Attribution

The pages_viewed array in the webhook identifies which pages are Relixir-managed content:

is_cms_content: Boolean indicating if the page is Relixir CMS content
cms_content_item_id: UUID of the Relixir content item if applicable

This enables attribution of which Relixir blogs drive traffic and engagement.

CMS Content Webhooks

When CMS content is published, updated, or deleted, Relixir sends a webhook with the following payload structure:

Payload Structure

{
  "event": "content.published",
  "timestamp": "2026-02-13T15:30:00Z",
  "data": {
    "item_id": "uuid-of-content-item",
    "slug": "my-article-slug",
    "title": "My Article Title",
    "collection_id": "uuid-of-collection",
    "organization_id": "uuid-of-organization",
    "action": "published"
  }
}

CMS Event Types

Event	Action	Description
`content.published`	`published`	First-time publish of a content item
`content.updated`	`updated`	Republish of an existing content item
`content.deleted`	`deleted`	Content item was deleted

Payload Fields

Field	Type	Description
`item_id`	string (UUID)	Unique identifier of the content item
`slug`	string	URL slug of the content item
`title`	string	Title of the content item (may be null)
`collection_id`	string (UUID)	ID of the collection containing the item
`organization_id`	string (UUID)	ID of your organization
`action`	string	Action that triggered the webhook

CMS webhooks are triggered for all deployment modes including hosted blogs, spreadsheet deployments, and external CMS integrations.

Troubleshooting

Webhooks are not arriving

Verify your endpoint URL is correct and publicly accessible
Ensure your endpoint returns a 2xx status code within 10 seconds
Check your server logs for incoming POST requests

CMS content not being tracked

Verify your blog posts are published (not drafts)
Check that deployment slugs match URL paths
Confirm BlogSettings.blogSlugPrefix is configured correctly

AI search not being detected

AI search detection uses referrer URLs and UTM parameters
ChatGPT doesn’t send a referrer, so it requires utm_source=chatgpt in your URLs
Verify UTM parameters are preserved when visitors land on your site

Missing company or contact data

Not all visitors can be identified at the contact level
Some visitors only have company-level identification
The company and contact fields are only present when data is available

Webhook Delivery

Relixir uses the following delivery behavior:

Setting	Value
Timeout	10 seconds
Retries	3 attempts with exponential backoff
Content Type	`application/json`

Your endpoint should return a 2xx status code to acknowledge receipt. Non-2xx responses (except 4xx client errors) trigger automatic retries.
