Is there Azure equivalent to Amazon AWS Slack notifications?

Question

In AWS I have code, which is used to send Slack notifications as following:

using Amazon.SimpleNotificationService;
using Amazon.SimpleNotificationService.Model;
..................
var client = new AmazonSimpleNotificationServiceClient(); // connect using network creds
var request = new PublishRequest(slackTopicArn, message);
var response = await client.PublishAsync(request);

This provides a simple, concise way to send Slack messages.

Is there an Azure functionality similar to this, or I must use web client with Slack URL??
