zoom-websockets

zoom-websockets is a skill for Claude Code from zoom/skills. It costs 59 tokens per session (1,991 once invoked), scanned A, original, MIT.

A persistent connection that lets Zoom send real-time event notifications to an application over WebSockets, a two-way connection that stays open.

In plain words
What is it for?
Use it for fast Zoom event updates, especially when the application needs a continuing connection, two-way communication, or tighter control over its exposed network surface.
Why use it?
It can deliver updates with low delay and without exposing a public notification endpoint, though it requires more connection and authentication setup than webhooks.

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

zoom-websockets scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 264 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Zoom WebSockets

Receive real-time event notifications from Zoom via persistent WebSocket connection.

WebSockets vs Webhooks

Aspect WebSockets Webhooks
Connection Persistent, bidirectional One-time HTTP POST
Latency Lower (no HTTP overhead) Higher (new connection per event)
Security Direct connection, no exposed endpoint Requires endpoint validation, IP whitelisting
Model Pull (you connect to Zoom) Push (Zoom connects to you)
State Stateful (maintains connection) Stateless (each event independent)
Setup More complex (access token, connection) Simpler (just endpoint URL)

Choose WebSockets when:

  • Real-time, low-latency updates are critical
  • Security is paramount (banking, healthcare, finance)
  • You don't want to expose a public endpoint
  • You need bidirectional communication

Choose Webhooks when:

  • Simpler setup is preferred
  • Small number of event notifications
  • Existing HTTP infrastructure

Prerequisites

  • Server-to-Server OAuth app or admin-managed General App in Zoom Marketplace
  • Client ID and Client Secret; S2S also requires the Account ID
  • WebSocket subscription with events enabled

Need to create/configure the app first? Use Marketplace app management for app creation, manifest validation, app-owned WebSocket/event subscription scopes, and the WEB_SOCKET subscription enum before connecting. Start from the General admin or S2S WebSocket base, then select the WebSocket delivery method under Features > Access.

Need help with S2S OAuth? See the zoom-oauth skill for complete authentication flows.

For a General App WebSocket subscription, use the app-owned token flow documented for that app. Do not copy the S2S account_credentials example below into a General App implementation.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
