For a game server this is how you run `stop`, `say hello` or `op someone` without holding a WebSocket open. A newline is appended if you leave it off, because a console reads lines and a command without one sits in the buffer looking like nothing happened. **Nothing comes back but an acknowledgement.** stdin is one-way; read what the command did with `GET /apps/{id}/logs`. Only templates that asked for stdin have a console to write to (`template.stdin`). The rest refuse with `TEMPLATE_HAS_NO_STDIN` rather than accepting a line that goes nowhere. **Required API key permission:** `apps:write` ## OpenAPI ````yaml /openapi.json post /apps/{id}/stdin openapi: 3.0.0 info: title: Storiza API version: '1.0' description: Manage Storiza servers, apps and subscriptions programmatically. servers: - url: https://api.storiza.store security: - bearerAuth: [] tags: - name: Servers description: Create, order, renew and upgrade VPS servers, and read their details. - name: Server power & commands description: >- Start, stop, reboot and force-stop a server, check its status and run commands on it. - name: Server settings description: >- Rename a server, reinstall its operating system and follow its installation. - name: Server firewall description: Turn a server's firewall on or off and manage its rules. - name: Server metrics description: CPU, memory, disk and network usage, now and over time. - name: Server backups description: Order the backup add-on, and take, list and delete backups. - name: Server snapshots description: Take, list and delete snapshots of a server. - name: Server sharing description: A share link that lets someone else open the server. - name: Server catalog description: >- Plans, operating systems, categories, datacenters and backup plans.
