Have you had experience using marketing platforms or tools for promotion and analytics?

Questions about my experience with marketing platforms or tools for promotion and analytics imply familiarity with systems that help collect user data, analyze behavior, and manage advertising campaigns.

Such tools include, for example:

• Google Analytics — for collecting and analyzing website visit statistics.
• Facebook Ads Manager — for setting up and monitoring advertising campaigns.
• Mixpanel or Amplitude — for advanced user behavior analytics.
• Mailchimp — for email marketing.

In the context of Go development, I have used APIs of these platforms to integrate analytics into applications, send events, and generate reports. For example, I sent user action events to Google Analytics via the Measurement Protocol.

An example of sending an event to Google Analytics (simplified):

import (
    "net/http"
    "net/url"
)

func sendEvent(category, action string) error {
    data := url.Values{}
    data.Set("v", "1")
    data.Set("tid", "UA-XXXXXX-Y") // Tracking ID
    data.Set("cid", "555")        // Client ID
    data.Set("t", "event")
    data.Set("ec", category)
    data.Set("ea", action)

    resp, err := http.PostForm("https://www.google-analytics.com/collect", data)
    if err != nil {
        return err
    }
    defer resp.Body.Close()
    return nil
}

This experience helps better understand how to integrate marketing analytics into applications.
