 If you're using any other type of endpoint, such as an HTTP trigger based Azure function, your endpoint code needs to participate in a validation handshake with Event Grid. Event Grid supports two ways of validating the subscription.
 
-1. **Synchronous handshake**: At the time of event subscription creation, Event Grid sends a subscription validation event to your endpoint. The schema of this event is similar to any other Event Grid event. The data portion of this event includes a `validationCode` property. Your application verifies that the validation request is for an expected event subscription, and returns the validation code in the reponse synchronously. This handshake mechanism is supported in all Event Grid versions.

-2. **Asynchronous handshake**: In certain cases, you can't return the ValidationCode in response synchronously. For example, if you use a third-party service (like [Zapier](https://zapier.com) or [IFTTT](https://ifttt.com/)), you can't programmatically respond with the validation code.

    Starting with version 2018-05-01-preview, Event Grid supports a manual validation handshake. If you're creating an event subscription with an SDK or tool that uses API version 2018-05-01-preview or later, Event Grid sends a `validationUrl` property in the data portion of the subscription validation event. To complete the handshake, find that URL in the event data and do a GET request to it. You can use either a REST client or your web browser.
