Use curl and jq with the Rack4 API
Drive the Rack4 API from a shell with curl and jq: filter servers, take snapshots and wait for them, read errors, page invoices, edit the firewall.
Receive Rack4 webhooks in Node.js and Python
A dependency-free webhook receiver in Node.js or Python that checks every Rack4 signature, refuses replays, skips duplicates and runs under systemd.
Relay Rack4 webhooks to Slack and Discord with Node.js
When the built-in Slack and Discord channels don't fit, run a small relay that verifies webhook signatures and posts events in your own format.
Script your infrastructure with the TypeScript SDK
Use @vpsnine/sdk from TypeScript to list servers, snapshot before a reboot, order a server safely and handle errors, with retries and idempotency keys built in.
