Foundry REST API
Connect
Waystone talks to a Rolemaster Unified world through the Foundry REST API module (the public relay at foundryrestapi.com, or your own). Keys stay in this browser and are sent only to the relay — never written into the app.
Step 1
Install the module in Foundry
In Foundry, install Foundry REST API from the package directory, or with the manifest URL from the module's GitHub releases. Enable it in the RMU world you want on this table (system id rmu).
Step 2
Get an API key
Create a free key at foundryrestapi.com (or on your self-hosted relay). In module settings, paste that key and set the WebSocket relay to wss://foundryrestapi.com unless you host your own.
Step 3
Paste the same key here
What Waystone calls
GET /clients, /world-info, /search, /get, POST /roll, /chat, /macro/:uuid/execute, /execute-js (to open journals on the canvas), and PUT /update for hits and power points.
