Sending Events

Learn how to send events to your Eventicat aggregator using simple HTTP requests.

Event Basics

Every event sent to Eventicat requires two pieces of information:

1. Aggregator ID (_id) - Identifies which aggregator receives the event
2. Event Name (name) - A string identifying the type of event

Events are sent to the /api/event endpoint using either GET or POST requests.

Endpoint

https://app.eventicat.com/api/event

Required Parameters

Parameter	Type	Location	Description
_id	string	URL query	Your aggregator ID
_apikey	string	URL query or Header	Your API key (see Authentication)
name	string	URL query or Body	The event name

Using GET Requests

GET requests are the simplest way to send events. All parameters are passed in the URL.

Basic Example

GET https://app.eventicat.com/api/event?_id=YOUR_AGGREGATOR_ID&_apikey=YOUR_API_KEY&name=user_signup

With cURL

curl "https://app.eventicat.com/api/event?_id=YOUR_AGGREGATOR_ID&_apikey=YOUR_API_KEY&name=user_signup"

tip

For production applications, use environment variables to store credentials and prefer POST requests with Bearer token authentication. See Language Examples for ready-to-use helper functions.

Using POST Requests

POST requests are recommended for production use, especially when using Bearer token authentication or sending tags.

Basic Example

curl -X POST "https://app.eventicat.com/api/event?_id=YOUR_AGGREGATOR_ID" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name": "user_signup"}'

Success Response

{
  "status": "ok"
}

Event Naming

Eventicat accepts any event name you send. There are no strict naming conventions—use whatever makes sense for your application.

Only Requirement

Event names must be URL-compatible (if using GET requests) and not cause HTTP 414 errors (URL too long).

Recommended Practices

While not enforced, these practices help keep your events organized:

• Be descriptive - user_signup is clearer than event1
• Stay consistent - Use the same style across your application
• Keep it reasonable - Very long names may be hard to read in reports

Examples

All of these work fine:

// Lowercase with underscores
await sendEvent('user_signup');

// CamelCase
await sendEvent('UserSignup');

// Kebab-case
await sendEvent('user-signup');

// Spaces (encoded in URLs)
await sendEvent('user signup');

// Mixed
await sendEvent('User_Signup_Event');

Choose what works best for your team and stick with it.

Testing Events

You can test your event integration using cURL:

# Quick test with URL parameters
curl "https://app.eventicat.com/api/event?_id=YOUR_AGGREGATOR_ID&_apikey=YOUR_API_KEY&name=test_event"

# Test with Bearer token
curl -X POST "https://app.eventicat.com/api/event?_id=YOUR_AGGREGATOR_ID" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name": "test_event"}'

Check your aggregator dashboard to verify the event was received.
