Webhooks

Webhooks are unique per partner and company!

Only one webhook can exists for a partner and company. You will only get updates notifications on candidates created under this context.

E.g. If you subscribe to a webhook using your Account API token you won't be get notified about updates on candidates created directly on the web application or other partners.

:global parameter

:global parameter is the only exception to the above. If global=true you will get notifications on all candidates created through the API. You still won't get notifications on candidates created from the web application as they don't belog to the API.
