All URLs are validated through a simple token exchange mechanism so we may trust that you actually control the target server. Note that validation happens right at webhook creation, meaning that we will issue a request to you before successfully registering the webhook. The validation will send a
GET request to your
url with a query string of
check=<random_string>, your webhook server should respond back with the
<random_string> to be validated.
If you use Zapier webhooks instead of your own backend's, validation will be automatic.
