Go

​

Installation

Install analytics-go using go get:

go get github.com/TONSolutions/telemetree-go

​

Quick Start

Create a Telemetree SDK client by providing the Project ID and API Key.

client, err := telemetree.NewClient(
	"YOUR_PROJECT_ID",
	"YOUR_API_KEY",
)

if err != nil {
	// handle error
}

​

Event Tracking

Send an event with user and event data.

err = client.Track(telemetree.Event{
	TelegramID: 112294972,     // User's Telegram ID (required)
	EventType:  "web",         // Event type (required)
	IsPremium:  true,          // Premium status flag (optional)


	Username:     "username",  // Username
	Firstname:    "firstname", // First name
	Lastname:     "Lastname",  // Last name
	Language:     "en",        // User's language
	ReferrerType: "web",       // Traffic source type
	Referrer:     "0",         // Traffic source
})

if err != nil {
	fmt.Println("Error track event:", err)
	return
}

Errors handling

The client returns typed errors, which are specifically defined in the github.com/Telemetree/telemetree-go/telemetree/errors package. These custom error types provide more detailed information about specific error scenarios, making error handling more precise and informative.

The following error types are defined in the github.com/Telemetree/telemetree-go/telemetree/errors package:

• ClientInitializationError: Represents errors occurring during client initialization, with an associated reason.
• EventValidationError: Represents validation errors for event fields, with the specific field that failed validation.
• EventPreparationError: Represents errors during event preparation, including a description of the failure.
• EventSendError: Represents errors encountered when sending events, with a description of the error.

You can use type assertion or errors.As to handle these errors in a type-safe manner and access the underlying details.

​

Encryption

The SDK uses RSA encryption to secure event data before sending it to the Telemetree service, ensuring data privacy. The publicKey is fetched automatically from the Telemetree configuration service during initialization, so there’s no need to manually set it.
