Go to make.powerautomate.com and sign in. In the left sidebar, click 'My flows', then click '+ New flow' in the top left. Select 'Automated cloud flow' from the dropdown. Give your flow a name like 'Slack Reaction to Notion Task'. You'll be prompted to choose a trigger — type 'Slack' in the search box.

1. 1Click 'My flows' in the left sidebar
2. 2Click '+ New flow' in the top left corner
3. 3Select 'Automated cloud flow' from the dropdown menu
4. 4Name the flow 'Slack Reaction to Notion Task'
5. 5In the trigger search box, type 'Slack' and press Enter

Flow editor > Trigger picker > Slack > When a reaction is added to a message

Set the Slack trigger to 'When a reaction is added to a message'

From the Slack trigger list, select 'When a reaction is added to a message'. This fires every time any user adds an emoji reaction in any channel your Slack bot has access to. You'll filter it to a specific emoji in a later step. Click 'Create' to confirm the trigger and open the flow editor.

1. 1Scroll through the Slack trigger list or search for 'reaction'
2. 2Select 'When a reaction is added to a message'
3. 3Click 'Create' to open the flow canvas with this trigger at the top

Flow canvas > Slack trigger block > Sign in

Connect your Slack workspace

Click the Slack trigger block. Power Automate will ask you to sign in to Slack. Click 'Sign in' and complete the OAuth flow in the popup window. You must authorize with an account that has access to the channels you want to monitor. After authorization, the trigger block will show your Slack workspace name next to a green checkmark.

1. 1Click the Slack trigger block to expand it
2. 2Click the 'Sign in' button that appears
3. 3Complete the Slack OAuth flow in the popup window
4. 4Grant Power Automate the requested permissions including reactions:read and channels:history
5. 5Return to the flow canvas — the trigger should now show your workspace name

Flow canvas > + New step > Control > Condition

Add a Condition to filter for your specific emoji

Click '+ New step' below the trigger. Search for 'Condition' and select the 'Condition' Control action. In the left value field, click inside and select 'Reaction' from the dynamic content panel — this is the emoji name that fired the trigger (without colons, e.g., 'ticket'). Set the operator to 'is equal to'. Type your chosen emoji name in the right value field, e.g., 'ticket'. This prevents the flow from creating a Notion entry for every single reaction in your workspace.

1. 1Click '+ New step'
2. 2Search for 'Condition' and select it from the Control category
3. 3Click the left value field in the Condition block
4. 4Select 'Reaction' from the dynamic content panel on the right
5. 5Set the operator dropdown to 'is equal to'
6. 6Type your emoji name in the right value field, e.g., 'ticket' (no colons)

Flow canvas > Condition > If yes > + Add an action > Slack > Get message

Fetch the original Slack message text

Inside the 'If yes' branch of the Condition, click '+ Add an action'. Search for 'Slack' and select 'Get message'. This action retrieves the full message text using the Channel ID and Message Timestamp from the trigger. Both fields are available in the dynamic content panel from the trigger. You need this step because the reaction trigger does not include the original message body — only the reaction name and message reference.

1. 1Click '+ Add an action' inside the 'If yes' branch
2. 2Search for 'Slack' in the action picker
3. 3Select 'Get message' from the Slack connector
4. 4In the 'Channel' field, select 'Channel ID' from the dynamic content panel
5. 5In the 'Message Timestamp' field, select 'Message Timestamp' from the dynamic content panel

Flow canvas > + Add an action > Data Operation > Parse JSON

Add a Parse JSON action to extract message fields

After the 'Get message' step, click '+ Add an action' and search for 'Parse JSON'. Select the 'Parse JSON' Data Operation action. In the Content field, insert the 'Body' output from the 'Get message' step using dynamic content. You need a schema — click 'Generate from sample' and paste in a sample Slack message payload. This makes individual fields like 'text', 'user', and 'ts' available as clean dynamic content tokens in subsequent steps.

1. 1Click '+ Add an action' after the 'Get message' block
2. 2Search for 'Parse JSON' and select it from Data Operation
3. 3In the 'Content' field, click the dynamic content panel and select 'Body' from the 'Get message' step
4. 4Click 'Generate from sample'
5. 5Paste a sample Slack message JSON payload and click 'Done'

Flow canvas > + Add an action > Slack > Get user

Resolve the Slack user ID to a display name

Click '+ Add an action' and search for 'Slack', then select 'Get user'. In the 'User' field, insert the 'user' token from the Parse JSON output. This call returns the user's profile including 'display_name' and 'real_name'. You'll use 'real_name' in the Notion task so reviewers know who flagged the message without decoding a user ID.

1. 1Click '+ Add an action' after the Parse JSON block
2. 2Search for 'Slack' and select 'Get user'
3. 3In the 'User' field, select the 'user' token from the Parse JSON dynamic content

Paste this expression into the 'Task Title' field of the Notion 'Create database item' action instead of the raw 'text' token. It trims whitespace, strips any leading emoji characters that Slack sometimes prepends, and truncates the title at 200 characters so Notion's title field doesn't overflow. Switch to the Expression tab in the dynamic content panel and replace the current value with this formula.

if(
  greater(length(trim(body('Parse_JSON')?['text'])), 200),
  concat(

if(
  greater(length(trim(body('Parse_JSON')?['text'])), 200),
  concat(
    substring(
      trim(body('Parse_JSON')?['text']),
      0,
      200
    ),
    '...'
  ),
  trim(body('Parse_JSON')?['text'])
)

Flow canvas > + Add an action > Notion > Create database item

Connect your Notion workspace

Click '+ Add an action' and search for 'Notion'. Select 'Create database item'. Click 'Sign in' to connect your Notion account via OAuth. You must be an admin or have full access to the target Notion database. After sign-in, the action will prompt you to select a Database — choose the Notion database where tasks should land.

1. 1Click '+ Add an action'
2. 2Search for 'Notion' and select 'Create database item'
3. 3Click 'Sign in' and complete the Notion OAuth flow in the popup
4. 4In the 'Database' dropdown, select your task tracking database

Flow canvas > Notion > Create database item > property fields

Map Slack data to Notion database fields

With the Notion 'Create database item' action open, map each Notion property to the corresponding Slack data. Set the Name/Title field to the 'text' token from Parse JSON. Set an Assignee or Reported By text field to 'real_name' from the 'Get user' step. Set a Source URL field to the Slack message permalink. Set a Status field to a default value like 'To Do'. Set a Created Date field using the expression 'utcNow()'. All tokens are available in the dynamic content panel.

1. 1Click the Title/Name field and select 'text' from the Parse JSON dynamic content
2. 2Click the Reported By field and select 'real_name' from the Get user dynamic content
3. 3Click the Source URL field and select 'permalink' from the Parse JSON dynamic content
4. 4Click the Status field and type 'To Do' as a static value
5. 5Click the Created Date field, switch to Expression tab, and type utcNow()

Flow canvas > + Add an action > Slack > Post message

Add a Slack reply to confirm task creation

After the Notion step, click '+ Add an action' and search for 'Slack', then select 'Post message'. Set the Channel field to the Channel ID from the trigger. In the Message Text field, compose a confirmation like: 'Task created in Notion: ' followed by the Notion page URL from the 'Create database item' output. Set Thread Timestamp to the Message Timestamp from the trigger so the reply threads under the original message instead of posting to the channel.

1. 1Click '+ Add an action' after the Notion step
2. 2Search for 'Slack' and select 'Post message'
3. 3Set Channel to 'Channel ID' from the trigger dynamic content
4. 4In Message Text, type 'Task created: ' then insert the Notion page URL from the Create database item output
5. 5Set Thread Timestamp to 'Message Timestamp' from the trigger to thread the reply

Flow canvas > Save > Test > Manually

Test and enable the flow

Click 'Save' in the top right, then click 'Test' and select 'Manually'. Go to Slack, find any message, and react to it with your chosen emoji. Switch back to Power Automate — the test run should appear within 60-90 seconds. Expand each action to confirm green checkmarks and review the outputs. Check Notion to verify a new database entry was created with the correct fields. If everything looks right, click 'Turn on' to activate the flow for production.

1. 1Click 'Save' in the top right corner
2. 2Click 'Test' and choose 'Manually'
3. 3Go to Slack and react to any message with your trigger emoji
4. 4Return to Power Automate and wait for the test run to appear (up to 90 seconds)
5. 5Expand each action block and confirm green checkmarks, then check Notion for the new entry
