Tracking API
Welcome to the Tracking API.
This API should be used when there is no module available for your language or they doesn't satisfy your needs.
We strive to keep it as simple as possible.
Type | Description | Requires extra data |
|---|---|---|
init | First event to send when starting the app | yes |
event | Default type, for reporting actions or anything else | no |
error | Submit an error, name should contain the error type | yes |
userid | Set a new user ID for this user | no |
props | Set propserties for this user ID based on the data field. | no |
heartbeat | Websockets only: send every minute to keep the connection on. This only require to pass the machineIdfield alongside | no |
The first thing you need to send when the user opens the app is an init event upon which most of the analytics relies on.
If you don't send it first, no data will appear in your dashboard.
Nucleus expect to receive the analytics data as a JSON object, containing a
data array property.This array should contain one or multiple events you want to report.
Basic events data
Parameter | Type | Optional | Description |
|---|---|---|---|
type | String | optional | Event type, see below for all the possible values (default: "event") |
name | String | required if type is event or error | Name of the event |
sessionId | Integer | required | 4-digits number that identifies the current session |
date | String | optional | Date/time of the event (ISO 8601 or milleseconds since 1970). If not provided we'll use the time the server receives the event. |
id | String | optional | Short ID that will be returned in confirmation |
userId | String | optional | Identify the user with user-facing ID like email, username.. |
anonId | String | optional | Unique user identifier. Ideally should be a nanoid of 12 chars. More reliable than userId and can be used to track anonymous users. |
deviceId | String | required | Hashed identifier of the machine (ie mac adress) |
payload | Object | optional | Aditionnal data attached to the event |
Extra events data
If you are reporting either an error or the first init event, you can attach those extra data:
Parameter | Type | Optional | Example | Description |
|---|---|---|---|---|
platform | String | required | darwin | Usually 'win32', 'windows', 'mac', 'darwin' or 'linux' |
osVersion | String | required | 18.2.0 | Current installed version of the OS |
totalRam | Integer | required | 8 | Total RAM available on the user device |
version | String | required | 0.1.0 | Version of the app installed |
language | String | required | en-US | Locale of the user |
They are not required with regular events to save bandwidth.
Example:
{
"data": [{
"event": String, // Name of the event
"id": String, // OPTIONAL A random id for the event that will be returned when the query succeeds, can be used to make sure no events are reported two times.
"userId": String, // A string to identify the user
"anonId": String, // 12 chars nanoid identifying the user
"deviceId": String, // A hashed identifier of the machine
"sessionId": Int, // A random 4-digits number that identifies the current session
"platform": String, //
"osVersion": String, // The version of the OS
"totalRam": Int, // The total number of RAM available, in GB
"version": String, // Installed version of the app
"language": String, // Locale of the user (i.e. 'en-US')
"payload": {} // Any additionnal data that you want to report along the event }]
}
This is the recommended protocol to submit data.
It is the most efficient in terms of bandwidth and battery. This is what the modules use behind the scenes.
Latency will be vastly better compared to normal HTTP requests.
Endpoint:
wss://app.nucleus.sh/:appId/Send your data as a JSON serialized string message.
To prevent data lost due to network errors, when Nucleus receives an event it will send your client a message containing an array
reportedIds of the previously reported events so you can safely assume they were handled by the server.
