Introduction

Use the Cometly API to send events from all your data sources to Cometly.

The Cometly API will receive data from your data sources so Cometly can match events back to the correct site visitor profile and ad. It's a requirement that the Comet script is installed on each page of your site just above the </head> tag for Cometly to accurately attribute events.

The Cometly API will only work for Events spaces (workspaces). Please ensure your space is a Events space prior to setup.

For the highest attribution accuracy, we recommend sending a IP and fingerprint and comet_token.

The fingerprint should be obtained from the available cometFingerprint() function available via the Cometly Pixel base code present on all pages of the site.

The comet_token should be obtained from the available cometToken() function available via the Cometly Pixel base code present on all pages of the site.

The Cometly Pixel is a small piece of code that gives you a clearer insight into your website visitors. It tracks the pages they visit and automatically updates their profile when they submit forms. Be sure to place the pixel on every page of your website, right before the </head> tag ends.

And remember, it’s crucial to include it on every step of your customer's journey, whether that's within your sales funnels or across multiple domains. What’s more, the Cometly Pixel is intuitive—it doesn't just recognize users across different devices, it also knows when the same person returns to your site. This means you'll always know when someone comes back, giving you a full view of each visitor's interaction with your site over time.

Automatic Form Data Capture:
The Cometly base pixel will automatically updates the visitors profile when a form is filled out. You will automatically see the first name, last name, (or full name), email, and phone number inside Cometly if the visitor came from an ad. Each space in Cometly has a unique Cometly Pixel. You need to ensure you have the correct Cometly pixel if you are using multiple spaces in your account.

For any questions, please contact developers@cometly.com

Script Installation

Each space (workspace) inside Cometly has a unique script. It's a requirement that the script is installed on each page of your site just above the </head> tag for Cometly to accurately attribute events

Obtaining Your Script
Cometly accounts can have multiple spaces (workspaces) and each space has a unique script. Ensure you are installing the correct script on your site if you have multiple spaces.

Visit the Events Manager inside your Cometly account to retrieve the script.
‍

On the Events Manager page, click Setup Events and copy the pixel. Install the script just above the </head> tag on every page of your site.

Since you're using the API to send events, you do not need to proceed to 'Step 2: Add your events'.

API Token

Each space (workspace) inside Cometly has a unique API token.

Obtaining Your API Token
Cometly accounts can have multiple spaces (workspaces) and each space has an API token. Cometly API can only work for Comet Events spaces.

Visit the Space Settings Integrations page for the Cometly space that you want to receive data, click Cometly API, and generate a new API token.

For security reasons, the API token will only be shown once, make sure to copy this token to a safe place. If you lose the token, you can always regenerate a new token in the future.

Authentication

Authorization

Put the access token in the ‍Authorization: Bearer <TOKEN> header.
‍
Example: ‍Authorization: Bearer 123
‍

Required Headers
‍
Accept: ‍application/json
‍
Content-Type: ‍application/json

Endpoints

As of right now, we only have one endpoint which allows the posting of an event to our tracking engine.

All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail.

Important:
If your event is associated with personal identifiable information, please include the email, name, and phone strings to fully use the Customer Journey feature. Please include as many attributes as possible below to improve accuracy.

Note: It's highly recommended that you include an IP, email, comet_token and fingerprint for the best attribution accuracy.

If you cannot retrieve the fingerprint + IP or comet_token, you must send the email field and Cometly will attribute by email only. This could limit attribution accuracy depending on your marketing funnel. When only sending the email field, your marketing funnel must have a form in the beginning pages of the marketing funnel with an email field that our script will automatically capture.

For any questions, please contact developers@cometly.com

Required fields

event_name string
One of the following events is required:
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
email string
*required if both fingerprint and IP are missing
fingerprint string

*required if email is missing
‍
The fingerprint should be obtained from the available cometFingerprint() function available via the Cometly tracking code. The function returns a promise that resolves to the fingerprint value.
comet_token string

*required if email or fingerprint + IP are missing
‍
The comet_token should be obtained from the cometToken() function available via the Cometly tracking code. The function returns a string.
ip string
*required if email is missing

ALL fields

Customer & Event Data:
full_name string
first_name string
last_name string
user_agent string
phone string
Remove symbols, letters, and any leading zeros. Phone numbers must include a country code to be used for matching (e.g., the number 1 must precede a phone number in the United States). Always include the country code as part of your customers' phone numbers, even if all of your data is from the same country.

Example
Input: US phone number (650)555-1212
Normalized format: 16505551212
Event Data:
event_time timestamp, should be UTC timezone
*recommended
Ecommerce Data:
order_id string
order_name string
checkout_token string
amount number
Meta Deduplication:
idempotency_key string

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 Events Log to Verify Incoming POST Requests

Cometly features an in-built events log system designed to help you monitor and validate the data you send through POST requests. This tool is invaluable for troubleshooting, ensuring that the data you're transmitting to our services is received correctly and in its entirety. Below, we've outlined the steps on how to utilize the events log for this purpose.

Accessing the Events Log
‍
Visit the Events Log page in the app to access the logs section. Please allow up to 15 minutes for the events to process and display in the Events Log. If you are not seeing any events, please contact support@cometly.com and we will assist.

Request ID's

Each API request has an associated request identifier. You can find this value in the response headers, under Request-Id. You can also find request identifiers in the URLs of individual request logs in your Dashboard. If you need to contact us about a specific request, providing the request identifier will ensure the fastest possible resolution.

Your API keys carry many privileges, so be sure to keep them secure! Do not share your secret API keys in publicly accessible areas such as GitHub, client-side code, and so forth.

Something Else

The Stripe API uses API keys to authenticate requests. You can view and manage your API keys in the Stripe Dashboard.

Test mode secret keys have the prefix sk_test_ and live mode secret keys have the prefix sk_live_. Alternatively, you can use restricted API keys for granular permissions.

Your API keys carry many privileges, so be sure to keep them secure! Do not share your secret API keys in publicly accessible areas such as GitHub, client-side code, and so forth.

Authentication to the API is performed via HTTP Basic Auth. Provide your API key as the basic auth username value. You do not need to provide a password.

If you need to authenticate via bearer auth (e.g., for a cross-origin request), use -H "Authorization: Bearer sk_test_4eC39HqLyjWDarjtT1zdp7dc" instead of -u sk_test_4eC39HqLyjWDarjtT1zdp7dc.

All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail.
