Post to Twitch Chat from OpenClaw

OpenClaw can schedule Twitch chat messages and announcements through the Postiz skill. You message OpenClaw with the text, whether it should be a plain message or a colored announcement, and a time, and it calls the Postiz CLI to queue the message for your Twitch channel.

How do you set up OpenClaw to post to Twitch?

Setup takes three commands: install the Postiz skill, sign in, and confirm OpenClaw lists it as eligible. After that you talk to OpenClaw in plain language and it runs the Postiz CLI for Twitch.

Setup once, then just ask

# Install the Postiz skill (ClawHub or the skills CLI)
openclaw skills install @nevo-david/postiz
# or: npx skills add gitroomhq/postiz-agent

# Sign in (OAuth2 device flow) or use an API key
postiz auth:login
# or: export POSTIZ_API_KEY=your_api_key

# Confirm OpenClaw can see the skill
openclaw skills list --eligible

# Then just ask OpenClaw from any chat app:
> Post a purple announcement in my Twitch chat
  at 7pm: "Going live in 10 minutes!"

OpenClaw: Done! Your Twitch announcement is scheduled for 7:00 PM.

How Postiz Becomes an OpenClaw Skill

When you install Postiz Agent globally, OpenClaw automatically discovers it by reading the bundled SKILL.md file. This file tells OpenClaw what commands are available, what environment variables are needed, and how to compose Twitch messages with the right settings.

✓Install from ClawHub with one command: openclaw skills install @nevo-david/postiz
✓OpenClaw reads the SKILL.md and learns all Postiz commands
✓Run openclaw skills check to confirm the postiz binary and credentials are in place
✓Skills are loaded on-demand, keeping the agent context clean
✓Works with any LLM backend: Claude, GPT, Gemini, Llama, and more

Install from ClawHub

# Install the Postiz skill from ClawHub
openclaw skills install @nevo-david/postiz

# Or with the skills CLI
npx skills add gitroomhq/postiz-agent

# Sign in with OAuth2 (or set POSTIZ_API_KEY)

Scheduled & Proactive

openclaw automations for recurring content

OpenClaw automations run on cron expressions in an isolated session and can announce results to a chat channel. Create one that drafts and schedules your Twitch content through Postiz, so nothing waits on a manual trigger.

openclaw automations (cron)

openclaw automations create "0 9 * * 1-5" \
  "Post a blue announcement in Twitch chat that the stream starts in 10 minutes and link to the schedule." \
  --name "Twitch daily post" \
  --session isolated \
  --announce --channel telegram \
  --to "<your chat id>"

# openclaw cron is an alias for the same command

✓Cron jobs for hands-free pre-stream and during-stream announcements
✓Structured JSON output lets OpenClaw verify each step succeeded
✓Announcement colors applied automatically based on your instructions

Also Works with Claude Code

Postiz works with any AI agent that can run commands or call MCP tools — you ask, the agent does the work. That includes Anthropic's Claude Code, which has its own guide for posting to Twitch from Claude Code.

Claude Code

by Anthropic

Claude reads the Postiz skill so it knows what it can do, then autonomously discovers your Twitch integration, picks the right message type and color, and sends the message.

Claude Code

> Send a purple announcement to Twitch:
  "Stream starting now! Let's build!"

Claude: Done! Scheduled on Twitch for
  tomorrow at 9:00 AM.

Twitch + Other Platforms

Announce your stream on Twitch and other platforms in a single request. Each platform gets its own settings.

Example

> Post "Excited to announce our new feature!" to
  Twitch and LinkedIn tomorrow at 9am, then schedule
  a daily tip on Twitch every weekday at 10am

OpenClaw: Done! Scheduled:
  - Twitch + LinkedIn: tomorrow 9:00 AM
  - Daily tips on Twitch: Mon-Fri 10:00 AM

Twitch rules OpenClaw has to follow

Postiz enforces these Twitch constraints when OpenClaw creates a post. Knowing them up front avoids a failed request.

✓messageType is message or announcement. Announcements stand out with a color bar, and announcementColor only applies when messageType is announcement.
✓Colors are limited to primary, blue, green, orange, and purple. Ask for one of those names.
✓Twitch chat messages are capped at 500 characters. Keep announcements short and link out.
✓Messages post to your own channel's chat. OpenClaw cannot post into another streamer's chat through Postiz.

OpenClaw and Twitch: frequently asked questions

How do I post to Twitch chat from OpenClaw?

Install the Postiz skill in OpenClaw, run postiz auth:login, and connect your Twitch account in Postiz. Then message OpenClaw with the text, a message type, and a time. OpenClaw schedules it with postiz posts:create and Postiz sends it to your channel's chat.

Can OpenClaw send Twitch announcements with colors?

Yes. Set messageType to announcement and pick announcementColor from primary, blue, green, orange, or purple. Say "purple announcement" in your message and OpenClaw applies both settings, so the message appears with Twitch's highlighted announcement bar. Plain messages ignore the color setting entirely.

Can OpenClaw announce my stream across Twitch, Discord, and X together?

Yes. Ask for all three in one request. OpenClaw creates a single Postiz post with the Twitch chat message, a Discord channel post, and a tweet, each with its own settings, and schedules them for the same go-live time. Each channel keeps its own character limit.

Does OpenClaw need Twitch developer credentials?

No. Postiz holds the Twitch OAuth connection, and OpenClaw only runs the Postiz CLI. You authenticate OpenClaw with postiz auth:login or a Postiz API key. There is no Twitch application, client ID, or chat bot token to configure in OpenClaw.

Can OpenClaw post to Twitch chat on a schedule?

Yes. Create an OpenClaw automation with a cron expression matching your stream schedule and a prompt that posts the going-live announcement through Postiz. Because Postiz delivers the message, it arrives on time even if OpenClaw is busy with other tasks.
