What it does
Monitors a specific Trello board for card movements between lists. When a task changes status, it extracts the task name and previous/new steps. It then formats this information into a bolded message and posts it to a designated Slack channel or user.
Step by step
- Configure the Trello trigger to listen for cardMoved events on a specific board ID.
- Map the extracted card title and list names to the Slack message payload structure.
- Use standard HTTP POST requests with API keys in headers for both Trello and Slack authentication.
Where the LLM does the work
- Generate concise, human-readable phrasing for the status change notification to ensure clarity in a busy channel.
- Design the formatting logic to bold key elements like task names while keeping the message scannable.
- Create error handling messages that explain integration failures without exposing sensitive API tokens.
Watch out for
Trello's webhook history only retains events for a short window so you must handle missed events gracefully or use polling as a fallback.
Incorrect board ID configuration will cause silent failures so validate the board connection immediately after setup.

Everything your agent needs, including the gotchas. Copy it and go.
You are helping me build the following AI agent workflow. ## Goal Trello to Slack Task Move Alerts: Monitors a Trello board for card moves and posts the task name and status change to a specified Slack channel or user. ## Specification - What it does: Monitors a specific Trello board for card movements between lists. When a task changes status, it extracts the task name and previous/new steps. It then formats this information into a bolded message and posts it to a designated Slack channel or user. - Trigger: Triggered by an event (Event · on Trello card move) - Autonomy: Fully hands-off - Expected setup effort: about an afternoon - Tools/services involved: - Trello: Trigger and data source for task moves - Slack: Send notification messages - HTTP Request: Retrieve Trello board ID via API ## Known pitfalls, handle each one explicitly in your implementation 1. Trello's webhook history only retains events for a short window so you must handle missed events gracefully or use polling as a fallback. 2. Incorrect board ID configuration will cause silent failures so validate the board connection immediately after setup. ## Reference implementation https://n8n.io/workflows/7616 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Project Management than Trello?
Yes. Trello is only the example project management in this recipe. The same flow works with Asana, Awork, ClickUp and Clockify. Swap the project management connection and keep the rest of the setup as written.
Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
Who it's for
Built for Ops-IT teams who need one more recurring task off a human's plate.
Founders and execs get the same output without having to ask someone else to run it.
