Send a test delivery
Send one signed delivery to this webhook destination, so you can check that your server verifies the signature and reads the body.
The delivery's test is true. It carries one invented event, company.name.changed,
for Beispiel GmbH, with a company id no company has and no register data. It is not a
change we observed. The same object is what your server receives.
Webhook destinations only. An e-mail address or a Slack channel answers 400 invalid_request, and so do a disabled destination and a webhook whose host is not a public
address. A webhook the plan does not cover answers 403 destination_requires_plan. You may
send at most 10 test deliveries in a rolling hour, to all your destinations together; the
next answers 429 rate_limited with Retry-After.
A test is sent once, without retries, and its outcome does not count towards switching the
destination off. The delivery's id is the svix-id of the signed request. A test is not
listed by GET /deliveries.
Free.
