Send a test event

Preview — this feature is being built; the design below is the spec.
POST https://app.syntic.ai/v1/webhooks/{webhook_id}/testSend a webhook.test event to the endpoint right away and report what happened. Use it after registering an endpoint or changing your verification code.
For how this fits into a full workflow, see Webhooks.
