Steps and UI details are based on platform versions at time of writing β€” check each platform for the latest interface.

Best for

Teams that collect bug reports and feature requests in Slack channels but need them tracked in Trello.

Not ideal for

Teams needing complex conditional routing or those already using dedicated bug tracking tools like Jira.

Real-World Example

πŸ’‘

A 12-person product team uses this to automatically create Trello cards when team members or customers post messages with πŸ› or πŸ’‘ emojis in their #feedback Slack channel. Before automation, the product manager manually copied 15-20 reports per week into Trello, taking 90 minutes and occasionally missing urgent bugs buried in chat history.

Step-by-Step Setup

1

Zaps > Create Zap > Choose App & Event

Connect Slack to Zapier

Navigate to Zapier and create a new Zap. Search for Slack in the trigger apps list. Select 'New Message Posted to Channel' as your trigger event. This trigger fires instantly when messages appear in your designated channel.

  1. 1Click 'Create Zap' from your Zapier dashboard
  2. 2Type 'Slack' in the trigger app search box
  3. 3Select 'New Message Posted to Channel' from the event list
  4. 4Click 'Continue' to proceed to account connection
βœ“ What you should see: You should see 'New Message Posted to Channel' selected with a blue Continue button active.
2

Account Setup

Authorize Slack Account

Connect your Slack workspace to Zapier by signing in. Zapier needs read access to channels and messages to detect new posts. Make sure you're signing in with an account that has access to the channels where bug reports are posted.

  1. 1Click 'Sign in to Slack' button
  2. 2Select your workspace from the dropdown
  3. 3Click 'Allow' to grant Zapier permissions
  4. 4Wait for the green 'Connected' confirmation
βœ“ What you should see: You should see your Slack workspace name with a green checkmark and 'Connected' status.
⚠
Common mistake β€” If you don't see your target channel in the next step, you may need admin approval for the Zapier app in your Slack workspace.
3

Trigger Setup > Channel Selection

Configure Channel and Filter Options

Select the Slack channel where bug reports are posted. Set up filters to only trigger on relevant messages. You can filter by emoji reactions, specific keywords, or user mentions to avoid creating Trello cards for every casual message.

  1. 1Choose your target channel from the Channel dropdown
  2. 2Leave 'Trigger Word' blank to catch all messages initially
  3. 3Set 'Bot Messages' to 'No' to ignore automated posts
  4. 4Click 'Continue' to test the trigger
βœ“ What you should see: The channel name appears selected and you see a sample message from that channel in the test results.
⚠
Common mistake β€” Private channels won't appear in the list unless the Zapier bot is specifically invited to them.

Test Trigger

Test Slack Trigger

Zapier will pull recent messages from your selected channel to use as sample data. Pick a message that represents the type of content you want to convert into Trello cards. This sample data will populate the field mapping in later steps.

  1. 1Click 'Test trigger' to fetch recent messages
  2. 2Review the sample messages that appear
  3. 3Select a message that contains bug report content
  4. 4Click 'Continue with selected record'
βœ“ What you should see: You should see message details including text content, user name, timestamp, and channel information.
⚠
Common mistake β€” If no messages appear, post a test message in your Slack channel and run the test again.

Zap Steps > + > Filter

Add Filter Step for Bug Reports

Add a Filter step to only process messages containing bug report indicators. This prevents the Zap from creating Trello cards for every message. Set up conditions that look for specific emojis, keywords like 'bug' or 'feature request', or mentions of your product team.

  1. 1Click the + icon to add a step
  2. 2Select 'Filter by Zapier' from the built-in apps
  3. 3Choose 'Only continue if' condition type
  4. 4Set up rules for Text 'contains' keywords like 'bug', 'issue', or specific emojis
βœ“ What you should see: The filter shows your conditions and indicates it will 'Continue' or 'Stop' based on message content.
⚠
Common mistake β€” Be careful with emoji filtering - copy the actual emoji character from Slack rather than typing emoji codes.
6

Action > Choose App

Connect Trello Account

Add Trello as your action app and authorize your account. Zapier needs write access to create cards in your boards. Make sure you connect with a Trello account that has edit permissions on your target board.

  1. 1Click + to add another step
  2. 2Search for and select 'Trello'
  3. 3Choose 'Create Card' as the action event
  4. 4Click 'Sign in to Trello' and authorize access
βœ“ What you should see: Trello appears connected with your username displayed and access to your boards confirmed.
⚠
Common mistake β€” If your target board doesn't appear in the dropdown, check that your Trello account has edit access to that board.

Action Setup > Board Selection

Select Target Board and List

Choose which Trello board and list will receive the new cards. Most teams use a 'Backlog' or 'Incoming' list for unprocessed reports. The board dropdown will show all boards where you have edit permissions.

  1. 1Select your project board from the Board dropdown
  2. 2Choose the target list (typically 'Backlog' or 'To Review')
  3. 3Verify the board and list names are correct
  4. 4Proceed to card details configuration
βœ“ What you should see: Both board and list names are populated and you can see the card setup fields below.

Action Setup > Card Details

Map Card Title and Description

Configure how Slack message content becomes the Trello card title and description. Use the message text for the description and create a descriptive title that includes the message type and user. This makes cards easily scannable in your Trello board.

  1. 1Set Name field to combine message type and username
  2. 2Map Description to the full message text from Slack
  3. 3Add the channel name and timestamp for context
  4. 4Include the original message permalink for reference
βœ“ What you should see: Card preview shows formatted title and description with Slack message content properly mapped.
⚠
Common mistake β€” Long Slack messages may get truncated in Trello - consider using a summary for the title rather than the full message text.

Action Setup > Labels & Members

Set Up Labels and Assignments

Configure automatic labeling and team member assignments based on message content or channel. Create rules that assign bug reports to developers and feature requests to product managers. Use existing Trello labels or create new ones for different report types.

  1. 1Select appropriate labels from your existing Trello labels
  2. 2Set up member assignments based on message content or channel
  3. 3Configure due dates if your team uses them for bug triage
  4. 4Add any custom fields your board requires
βœ“ What you should see: Cards will be created with consistent labels and assigned to the right team members automatically.
⚠
Common mistake β€” Team members must be added to the Trello board before you can assign cards to them - Zapier can't invite new members.
10

Test Action > Publish

Test and Activate Zap

Run a final test to ensure cards are created correctly with all fields populated. Check that the card appears in the right list with proper formatting, labels, and assignments. Once verified, turn on the Zap to start processing messages automatically.

  1. 1Click 'Test action' to create a sample Trello card
  2. 2Check your Trello board to verify the card was created correctly
  3. 3Review all field mappings and formatting
  4. 4Click 'Publish' to activate the Zap
βœ“ What you should see: A test card appears in your Trello board with all fields correctly populated and the Zap shows as 'On'.
⚠
Common mistake β€” The test will create a real card in your Trello board - remember to delete it if you don't want it in your actual workflow.

Analysis

VerdictWhy Zapier for this workflow

Use Zapier for this if your team already lives in Slack and Trello but wastes time manually copying bug reports between them. The setup is straightforward with good filtering options, and the webhook trigger means cards appear within seconds of reports being posted. Skip Zapier if you need complex conditional logic based on message content - Make handles multi-path routing much better.

Cost

Expect 1 task per message that matches your filter criteria. At 50 bug reports per month, you're looking at 50 tasks monthly on Zapier's paid plan ($19.99). Make would handle the same volume for free on their Core plan, saving you $240 annually if cost is your main concern.

Tradeoffs

Make beats Zapier here with better text parsing tools and conditional routing - their 'Text Parser' module handles regex patterns that Zapier's basic filters miss. N8n offers more sophisticated message analysis with its HTTP Request node for sentiment analysis APIs. Power Automate's 'AI Builder' can automatically categorize bug reports by severity better than keyword matching. But Zapier wins on setup speed - you'll have this running in 15 minutes versus an hour+ on other platforms.

You'll hit Slack's webhook delivery delays during high-traffic periods, causing 2-3 minute gaps between message posting and card creation. Trello's API occasionally returns duplicate card errors if users double-click the reaction emoji quickly - add a 5-second delay step to prevent this. Long message threads get truncated in Trello descriptions, so consider using the message permalink instead of copying full text for complex reports.

Ideas for what to build next

  • β†’
    Add Priority Detection β€” Use a Code step to analyze message content for urgency keywords and automatically set Trello due dates or priority labels.
  • β†’
    Create Status Updates β€” Set up a reverse automation that posts Slack notifications when Trello cards move to 'In Progress' or 'Complete' status.
  • β†’
    Implement Report Digest β€” Build a scheduled Zap that sends weekly summaries of all bug reports and feature requests to your product team.
