This POST endpoint is used to create a new webhook configuration for your account.
To set up a webhook, provide a target url and an array of event_types that the webhook should listen to.
Upon successful creation, the response will include a unique webhook_token associated with the newly registered webhook as well as webhook_secret which will be used to encrypt the incoming payloads.
This token can be used for future management of the webhook.
