šHelp Me Title: ChatGPT Slack event-trigger registration says ā@ChatGPT isnāt in the channel,ā but Slack API confirms membership
Hi everyone,
Iām a German user, and English isnāt my first language. Please excuse any awkward wording. I used ChatGPT to translate this post into English so I could explain the problem as clearly as possible. Thank you for your patience and help.
Iām trying to configure an event-triggered task in ChatGPT Work using a connected Slack workspace. The intended flow is:
- An n8n workflow posts a completed taskās result to a dedicated public Slack channel.
- A Slack event triggers a ChatGPT task.
- ChatGPT reads and reviews the result.
Step 1 works. ChatGPT can also read the channel through its connected Slack tools. However, creating the event-triggered task fails with:
āI couldn't create an immediate Slack monitor because u/ChatGPT isn't in [channel].ā
What we have verified:
- Iām using ChatGPT Plus in a desktop web browser.
- The connected Slack workspace and selected public channel are correct.
- A current Slack API channel-membership query explicitly lists both my user and the ChatGPT bot.
- Slackās installed-app configuration also lists the bot as belonging to that channel.
- OAuth authorization was renewed previously, but the registration error persisted.
- Slackās āAI agent experienceā setting is enabled for the ChatGPT app.
- No pending permission-update request was visible in the app-management pages we inspected.
- A manually sent channel message with a correctly resolved u/ChatGPT mention received no thread reply when checked about ten minutes later. A direct-message test also showed no response.
- Signing into admin.openai.com with the same account used for ChatGPT displays āAccess required.ā
- The setup link suggested by the registration error, https://chatgpt.com/slack-ai-app-install, redirects to the normal ChatGPT homepage without showing a setup flow.
One potentially relevant detail: Slack shows extensive permissions granted on behalf of my user, but the app-level permission shown in the installed configuration is limited to viewing messages that directly mention u/ChatGPT. I donāt know whether this is expected for this integration.
OpenAI Support has an open case. Its latest response has not confirmed the root cause or whether this feature is enabled for my specific Plus account.
We are keeping two questions separate:
- Why does event-trigger registration reject a bot whose channel membership is confirmed?
- Why does the installed bot not respond to an explicit mention?
We do not yet know whether these share a cause. The existing n8n-to-Slack workflow works, so Iād prefer to avoid another blind reinstall.
Has anyone successfully configured this exact setup with a personal Plus account?
Could we be confusing the personal Slack connector with a separately configured ChatGPT-in-Slack deployment? Is there a specific permission, installation step, or account eligibility requirement we should check?
Iām looking for a concrete diagnostic step or a confirmed working configuration. Happy to provide redacted screenshots or additional non-sensitive details.
Thanks for your help!
