Port

To change the port which Secured Signal API uses, you need to set service.port in your config. (default: 8880)

Token-specific ports (port realms)

You can additionally define a port per Token config.

note

Each port spawns a separate listener, beware that this can affect performance

When a token specifies a port, a new realm is created for that port.
Only tokens that explicitly belong to the same realm are accepted on that port.

Example

• TOKEN_1 → port 8880
• TOKEN_2 → port 8890

Requests behave as follows:

Token	Port	Result
TOKEN_1	8880	✅
TOKEN_2	8880	⛔️
TOKEN_1	8890	⛔️
TOKEN_2	8890	✅

If a token config does not specify a port, it automatically gets assigned to the default realm.

This allows strict separation of access by port without running multiple instances.
