Learn how to send Signalgrid push notifications from .NET applications
Signalgrid makes it straightforward to send notifications from .NET / C#. The platform uses a simple model built around your client_key, a target channel, and a few core fields such as title, body, type, and optional critical.
.NET applications can use Signalgrid for deployment updates, monitoring alerts, admin workflows, and business systems that need a clean API integration.
What you need
- A Signalgrid account
- Your client key
- A channel token
- .NET / C# available in your environment
Basic example
The following example sends a simple notification with .NET / C#.
using System.Net.Http;
var client = new HttpClient();
var payload = new FormUrlEncodedContent(new[]
{
new KeyValuePair("client_key", Environment.GetEnvironmentVariable("SIGNALGRID_CLIENT_KEY") ?? ""),
new KeyValuePair("channel", Environment.GetEnvironmentVariable("SIGNALGRID_CHANNEL") ?? ""),
new KeyValuePair("title", "Deployment Finished"),
new KeyValuePair("body", "The production deployment completed successfully"),
new KeyValuePair("type", "SUCCESS")
});
var response = await client.PostAsync("https://api.signalgrid.co/v1/push", payload);
var result = await response.Content.ReadAsStringAsync();
Console.WriteLine(result); Required fields
