How to integrate Azure Functions, GIPHY and Microsoft Teams?

Today I have pretty funny topic to show you all - we'll try to create a simple Azure Function, which will... find a random GIF image and post in on a channel in Microsoft Teams! Why such article? Well, we can't always do serious things :)

To bo honest, such triangle shows easily how to achieve integration on a corporate level using minimal resources. 


To start you have to have a Microsoft Teams channel created. I won't go into details of creating one(since it's pretty basic stuff) and just assume, you already have one. What we're interested in are the Connectors available:

When you click on the menu item, you'll see a window with many available connectors. We're searching for a particular one named Incoming Webhook:

When you click Configure, you'll see a simple wizard where you can insert a name of a WebHook and select an image. Once you click Create, a webhook URL will be provided so copy and save it. It'll look like this:

Now we have to create a function.


I decided to create a function, which will be triggered from Monday to Friday at 9:30 AM. To do so selected TimerTrigger with the following signature:

[TimerTrigger("0 30 9 * * 1-5")]TimerInfo myTimer

The whole code looks like this:

public static class GiphyTrigger
	private const string WebhookUrl = "";

	private static Lazy<HttpClient> HttpClient = new Lazy<HttpClient>(() => new HttpClient());

	public static async Task Run([TimerTrigger("0 30 9 * * 1-5")]TimerInfo myTimer, TraceWriter log)
		log.Info($"C# Timer trigger function executed at: {DateTime.Now}");

		var randomGif = await HttpClient.Value.GetAsync("");
		var content = await randomGif.Content.ReadAsStringAsync();
		var model = JsonConvert.DeserializeObject<GiphyModel>(content);

		log.Info($"Sending GIF to Microsoft Teams");
		var result = await HttpClient.Value.PostAsync(WebhookUrl, new StringContent($"{{\"@type\": \"MessageCard\",\"@context\": \"\",\"summary\": \"This is GIF\",\"themeColor\": \"0075FF\",\"sections\": [{{\"startGroup\": true,\"title\": \"**GIPHY says:**\",\"text\": \"![Text]({model.Data.Url})\"}}]}}"));

		log.Info($"Result is {result.StatusCode}");

public sealed class GiphyModel 
		public GiphyDataModel Data {get;set;}

public class GiphyDataModel
	public string Title {get;set;}
	public string Url {get;set;}

In general it's more or less generic code, which calls GIPHY API and obtains a random gif. One thing is important however - when calling a webhook, the body of a request is a valid Actionable message, which is a special schema used within Office 365. You can find more info here.


When a function is triggered, you may see following result:

I named my webhook Squirrel Commando, and now it greets me everyday with a random GIF. Of course you can use Incoming Webhooks in Microsoft Teams for more serious tasks(like some reports, alerts or notifications) and integrate all using Azure Functions(with Consumption Plan it'll cost you almost nothing...) - with such generic functionality, only the sky is the limit.
