Overview

This endpoint allows you to send event data to Cometly for tracking conversions, page views, and other user interactions. Events are processed asynchronously and will be queued for processing.

Request Body

Identification Requirements

At least one of the following identification methods is required:

Email: User’s email address
Comet Token: Cometly tracking token
Fingerprint + IP: Both fingerprint and IP address must be provided together

string

required

The name of the event being tracked. Use one of the standard events or a configured custom event.Standard Events:

lead_generated
view_content
schedule
purchase
subscribe
add_to_cart
contact
initiate_checkout
add_payment_info
complete_registration
start_trial
sign_up
submit_application
webinar_registration

Custom Events: Custom events are named custom_event_1 through custom_event_50. View our help article to learn how to configure custom events prior to sending to Cometly.

Tracking Parameters

string

User’s email address. Can be used as the primary identification method.

string

Cometly tracking token. Can be used as the primary identification method.

string

Browser fingerprint for user identification. Must be provided together with ip.

string

User’s IP address. Must be provided together with fingerprint.

string

Custom tracking identifier. Events with the same tracking_id will be attributed to the same contact.

string

Groups this contact into a company using your own account or company identifier. Nullable; accepts a string or integer, trimmed, 1–190 characters after trimming. The value is case-preserved and stored byte-exact — it is never lowercased. A blank string is treated as absent (null). Sending a float, array, or boolean returns a 422.This is unrelated to tracking_id: tracking_id merges events into a single contact and never groups companies, while company_external_id groups contacts into a company and never merges contacts or takes part in contact matching. Never send a shared account ID as tracking_id.Only honored when the Space’s company identity mode is set to External ID in Space Settings. In the default Auto mode (companies grouped by business-email domain), the value is still accepted and stored, but ignored for grouping.

string

Display name for the company identified by company_external_id. Nullable; accepts a string or integer, trimmed, 1–255 characters after trimming. A blank string is treated as absent (null). Sending a float, array, or boolean returns a 422.Last write wins, and the value is never used for matching — two companies with the same name stay separate. Ignored when company_external_id is not also provided, since company_name alone doesn’t identify a company to name.

User Information

string

User’s full name

string

User’s first name

string

User’s last name

string

User’s phone number

Session Information

string

Browser user agent string

string

Timestamp of when the event occurred. Accepts ISO 8601 format or Unix timestamp in seconds.

string

The URL where the event occurred

Ecommerce Data

number

Transaction amount (for purchase events)

string

Unique order identifier. This field is used in our deduplication logic — if multiple events are sent with the same order_id, they may be treated as duplicates. Ensure each distinct order uses a unique value.

string

Order name or description

string

Checkout session token

boolean

Indicates if this is an upsell transaction

string

Common identifier linking upsells to original orders

Custom Fields

string

Custom profile field values passed as root-level properties. Fields 1-15 accept text, 16-25 accept numbers, 26-30 accept dates.Example: "profile_field_1": "Enterprise", "profile_field_16": "500"

Advanced Options

string

Unique key to prevent duplicate event processing. Use this to safely retry requests.

boolean

Set to true to prevent this event from being sent to Conversions API integrations

Response

Success Response

number

HTTP status code (202)

string

Success message indicating the event was queued

Error Response

string

Error description explaining what went wrong

Meta Deduplication

The idempotency_key in our API is a unique identifier that ensures data consistency and prevents duplication of events. You can extract the event_id from the Meta browser pixel and use it as the idempotency_key when interacting with our API. Upon an attributed Meta ad conversion event, we will send this value as event_id to prevent duplication, enabling Meta to recognize the event_id and deduplicate browser events.

Use the idempotency_key parameter to safely retry requests without creating duplicate events. The same idempotency key will prevent the event from being processed multiple times.
