Response status code does not indicate success: 400 (Bad Request)

Alex Prismotrov

Hi! Getting error 400. My code:
 

public async Task TrackEventAsync(string userId, string eventType, object eventProperties)<br />{<br />    var eventData = new<br />    {<br />        api_key = _apiKey,<br />        event_type = eventType,<br />        user_id = userId,<br />        event_properties = eventProperties<br />    };<br /><br />    var json = JsonSerializer.Serialize(eventData);<br />    var content = new StringContent(json, Encoding.UTF8, "application/json");<br /><br />    try<br />    {<br />        var response = await _httpClient.PostAsync("https://api.amplitude.com/2/httpapi", content);<br />        response.EnsureSuccessStatusCode();<br />        _logger.LogInformation("Event tracked successfully: {EventType}", eventType);<br />    }<br />    catch (HttpRequestException ex)<br />    {<br />        _logger.LogError(ex, "Error sending event to Amplitude: {EventType}", eventType);<br />    }<br />}

Any ideas how to figure out the issue?
