Events subscription via webhooks

[Surbhidhingra]

Hi,

I am implementing events subscription using MS graph android SDK. Below is the code.

IGraphServiceClient mGraphServiceClient = GraphServiceClientManager.getInstance(context).getGraphServiceClient(); mGraphServiceClient.getSubscriptions().buildRequest().post(getSubscription(email, expirationDate), subscriptionICallback);

private Subscription getSubscription(String email, Calendar expirationDate) {
        Subscription subscription = new Subscription();
        subscription.expirationDateTime = expirationDate;
        subscription.notificationUrl = "<Webhook link>";
        subscription.changeType = "created,updated";
        subscription.resource = "me/events";
        subscription.clientState = Base64.encodeToString(email.getBytes(), Base64.URL_SAFE | Base64.NO_PADDING | Base64.NO_WRAP);

        return subscription;
    }

The request body generated through this always throws the error:

but the same request body is working fine in graph explorer, I have tried many things now but unable to resolve it. Please help me how to work for subscription in android as I can't find any resources for this online.

It's urgent, appreciate your help. Thanks!

The issue was due to the BaseSubscription model in Microsoft graph SDK where it is setting "@odata.type":"microsoft.graph.subscription" by default and subscription api is not supporting this in request body and throwing the error: 400

So I resolved it by explicitly making "@odata.type" to null in the subscription model and pass it to post request which worked successfully for me.

Thanks!
