The Authentication overview | Pexip Infinity Docs documentation only appears to deal with inbound authentication but it doesn’t specify that it only deals with “inbound”.
It should either specify that it is only considering inbound authentication here, or it should be extended to also include “outbound” authentication configuration.
For instance, the documentation here doesn’t indicate that Basic Auth (a username and password) is the only configurable option for outbound Event Sinks.
If including outbound authentication, then the table in the documentation needs a new column “Basic Auth” and a new row “Event Sink”, and possibly an adjustment to visually indicate whether this authentication type relates to an inbound authentication or an outbound authentication.
