How to Send Asana Milestone Updates to Slack with Make

make.com > Scenarios > Create a new scenario

Create a new scenario in Make

Log in to Make at make.com and click the blue 'Create a new scenario' button in the top right of the Scenarios dashboard. You'll land on a blank canvas with a large circle in the center — this is where your first module goes. Click the circle to open the app search panel. Type 'Asana' and select it from the results.

1. 1Click 'Create a new scenario' in the top right
2. 2Click the large circle in the center of the canvas
3. 3Type 'Asana' in the search field
4. 4Select 'Asana' from the app list

Asana module list > Watch Tasks

Set the Asana trigger to watch tasks

From the Asana module list, select 'Watch Tasks'. This trigger polls Asana on a schedule you define and returns tasks that have changed since the last run. You'll be prompted to connect your Asana account — click 'Add' and authorize Make via OAuth. Once connected, you'll see fields to configure the workspace, project, and what to watch.

1. 1Select 'Watch Tasks' from the Asana module list
2. 2Click 'Add' next to the Connection field
3. 3Authorize Make in the Asana OAuth popup
4. 4Select your Asana workspace from the dropdown
5. 5Select the specific project or leave blank to watch all projects

Asana module > Clock icon > Scheduling

Configure the polling schedule

Click the clock icon at the bottom left of the Asana module to open the scheduling panel. Set the interval to 15 minutes — this is the minimum on most Make plans and gives a reasonable balance between freshness and operation cost. For deadline-proximity alerts (e.g., tasks due in 24 hours), 15 minutes is precise enough. Click 'OK' to save the schedule.

1. 1Click the clock icon at the bottom left of the Asana trigger module
2. 2Set 'Run scenario' to 'At regular intervals'
3. 3Set the interval to '15 minutes'
4. 4Click 'OK'

Asana module output > Wrench icon > Add a router

Add a router to split milestone vs. deadline logic

Click the small wrench icon on the Asana module output and select 'Add a router'. A router splits one data flow into multiple branches, each with its own filter. You need two branches: one for completed milestones and one for tasks with an approaching due date. The router appears as a diamond shape on the canvas with two output paths.

1. 1Hover over the output dot on the right side of the Asana module
2. 2Click the wrench icon that appears
3. 3Select 'Add a router' from the menu
4. 4Confirm two output paths appear from the router module

Router > Route 1 > Filter icon

Set the filter for completed milestones

Click the filter icon (a small funnel) on the first route coming out of the router. Set the condition: 'Completed' equals 'True'. If your Asana workflow uses a custom field or tag to mark milestones separately from regular tasks, add a second condition: the task name or custom field contains the text 'milestone' (case-insensitive). Click 'OK' to save the filter.

1. 1Click the funnel icon on the first route from the router
2. 2Set Condition 1: 'Completed' > 'Equal to' > 'True'
3. 3Click 'Add AND condition'
4. 4Set Condition 2: 'Name' > 'Contains (case insensitive)' > 'milestone'
5. 5Click 'OK'

Router > Route 2 > Filter icon

Set the filter for approaching deadlines

Click the filter icon on the second route. Set the condition to check if the task due date is within the next 24 hours. In Make's filter, use: 'Due On' is greater than or equal to 'now' AND 'Due On' is less than or equal to 'addDays(now; 1)'. This catches tasks due within one day. Adjust to 'addDays(now; 2)' if you want 48-hour warnings.

1. 1Click the funnel icon on the second route from the router
2. 2Set Condition 1: 'Due On' > 'Greater than or equal to' > 'now'
3. 3Click 'Add AND condition'
4. 4Set Condition 2: 'Due On' > 'Less than or equal to' > type 'addDays(now; 1)'
5. 5Click 'OK'

Route 1 > + > Slack > Create a Message

Add a Slack module to Route 1 (milestone complete)

Click the empty module slot at the end of Route 1 and search for 'Slack'. Select 'Create a Message'. Connect your Slack account via OAuth if you haven't already. Set the channel to the specific Slack channel for project updates (e.g., #project-milestones). In the message text field, build the message using Asana field variables — click inside the text field to open the variable picker.

1. 1Click the empty module at the end of Route 1
2. 2Search for 'Slack' and select it
3. 3Choose 'Create a Message'
4. 4Click 'Add' to connect your Slack account via OAuth
5. 5Set the Channel field to your target channel (e.g., #project-milestones)
6. 6Click inside the Text field and use the variable picker to build your message

Slack module > Text field > Variable picker

Build the milestone completion message

In the Slack 'Create a Message' text field, compose the message using Asana variables. Click the variables panel to insert fields directly. Build a message like: ':white_check_mark: *Milestone Complete:* {{task.name}} | Project: {{task.projects[].name}} | Completed by: {{task.assignee.name}} | Due was: {{formatDate(task.due_on; "MMM D, YYYY")}}'. This gives Slack readers the key facts without needing to open Asana.

1. 1Click inside the Text field in the Slack module
2. 2Type ':white_check_mark: *Milestone Complete:*'
3. 3Click the variable picker icon and insert 'Name' from the Asana task data
4. 4Insert 'Projects > Name' for the project name
5. 5Insert 'Assignee > Name' for the assignee
6. 6Insert 'Due On' wrapped in formatDate() for the due date

📬 New entry: {{1.name}}
Email: {{1.email}}
Details: {{1.description}}

Route 2 > + > Slack > Create a Message

Add a Slack module to Route 2 (deadline approaching)

Repeat the Slack module setup for Route 2. This time, post to a different channel if relevant (e.g., #project-deadlines) or the same channel with different text. Build a warning-style message: ':warning: *Deadline in 24 hours:* {{task.name}} | Project: {{task.projects[].name}} | Assignee: {{task.assignee.name}} | Due: {{formatDate(task.due_on; "MMM D, YYYY")}}'. The urgency framing helps readers act faster.

1. 1Click the empty module at the end of Route 2
2. 2Search for and select 'Slack', then 'Create a Message'
3. 3Reuse the existing Slack connection
4. 4Set the Channel to your deadline alert channel
5. 5Build the deadline warning message using Asana variables

Canvas > Run once button (bottom left)

Run the scenario once manually to test

Click 'Run once' at the bottom left of the canvas. Make will execute the scenario immediately against real Asana data. Watch the bubbles above each module — green means data flowed through, blue with a number means that many records were processed, red means an error. Click any bubble to inspect the exact data that passed through that module. Confirm the Slack message appears in the target channel.

1. 1Click 'Run once' at the bottom left of the scenario canvas
2. 2Watch the execution bubbles appear above each module
3. 3Click the bubble on the Asana module to verify task data was fetched
4. 4Click the bubble on each Slack module to confirm message payload
5. 5Check the target Slack channel for the test message

Canvas > Scenario toggle (bottom left) > On

Activate the scenario

Once the test passes, click the toggle at the bottom left of the canvas to switch the scenario from Off to On. The toggle turns blue. Make will now run the scenario automatically on your 15-minute schedule. Check the 'History' tab after the first scheduled run to confirm it executed cleanly and no errors appear in the log.

1. 1Click the toggle switch at the bottom left of the canvas
2. 2Confirm the toggle turns blue and shows 'On'
3. 3Navigate to the 'History' tab in the scenario header
4. 4After 15 minutes, refresh and confirm a successful run entry appears

Paste this formula into the Slack message Text field on both Route modules to build clean, conditional messages. The if() handles null assignees, substring() truncates long task names to 60 characters, and formatDate() normalizes the Asana date string. Replace the variable names with the actual Make variable tokens from the picker — the formula logic stays identical.

{{if(length(1.name) > 60; substring(1.name; 0; 60) & "..."; 1.name)}}

:white_check_mark: *Milestone Complete*
