This commit adds a new function `ConstructEvent` which is used to decode the contents of an HTTP request body into a type `WebhookEvent` that can be used to handle individual webhook events. The function also performs validation of the webhook signature prior to decoding. This is done by generating an HMAC256 hash of the request contents and checking that it matches the value provided in the `Signature` header. Signed-off-by: David Bond <[email protected]>
