Step-by-Step Setup

1

Dashboard > Create a New Scenario

Create new scenario in Make

Log into Make and click Create a New Scenario. You'll see the scenario builder with an empty canvas. Click the large plus icon in the center to add your first module. This opens the app selection dialog where you'll choose your trigger.

  1. 1Click 'Create a New Scenario' from your dashboard
  2. 2Click the large plus icon in the scenario canvas
  3. 3Search for 'Basecamp' in the app list
  4. 4Select 'Basecamp 3' from the results
What you should see: You should see the Basecamp module configuration panel open on the right side of the screen.
2

Basecamp 3 > Watch Events

Configure Basecamp webhook trigger

Select 'Watch Events' as your trigger module. This creates a webhook that Basecamp will ping whenever project events occur. Make generates a unique webhook URL that you'll need to copy for the next step. The webhook supports multiple event types from the same Basecamp account.

  1. 1Choose 'Watch Events' from the Basecamp module options
  2. 2Click 'Add' next to the Connection field
  3. 3Enter your Basecamp account credentials to authenticate
  4. 4Copy the webhook URL that Make generates
What you should see: You should see a webhook URL starting with 'https://hook.make.com' in the module settings.
Common mistake — The webhook URL is account-specific and changes if you recreate the module, so save it immediately.

Basecamp Project > Campfire > Configure Integrations

Set up Basecamp webhook in your account

Open your Basecamp account and navigate to the project you want to monitor. Go to the Campfire chat area and click on 'Configure integrations'. Add a new webhook integration using the URL from Make. Choose which events to send: recordings (updates), todos (tasks), and schedule items (milestones).

  1. 1Open the Basecamp project you want to monitor
  2. 2Click 'Campfire' in the project navigation
  3. 3Click 'Configure integrations' at the top
  4. 4Select 'Webhook' and paste your Make URL
  5. 5Check boxes for recordings, todos, and schedule events
What you should see: Basecamp shows 'Webhook configured' with a green checkmark next to your Make URL.
Common mistake — Webhooks are configured per-project in Basecamp, so repeat this for each project you want to monitor.
4

Make Scenario > Run Once

Test the Basecamp connection

Return to Make and click 'Run Once' to activate the webhook listener. Go back to your Basecamp project and create a test update or complete a task. Make should receive the webhook within 10 seconds and display the event data structure.

  1. 1Click 'Run Once' in the Make scenario
  2. 2Switch to your Basecamp project tab
  3. 3Post a message update or complete a task
  4. 4Return to Make and wait for the webhook to fire
  5. 5Click on the Basecamp module to see received data
What you should see: The Basecamp module shows a green badge with '1' and displays JSON data when clicked.
Common mistake — If no data appears after 30 seconds, check that your webhook URL in Basecamp exactly matches the one from Make.

Basecamp Module > + > Slack > Send a Message

Add Slack module

Click the plus icon after your Basecamp module to add Slack. Choose 'Send a Message' as the action type. This sends a formatted message to any Slack channel you specify. The module needs authentication to your Slack workspace and channel selection.

  1. 1Click the plus icon after the Basecamp module
  2. 2Search for and select 'Slack'
  3. 3Choose 'Send a Message' from the actions list
  4. 4Click 'Add' next to Connection and authenticate with Slack
What you should see: The Slack module opens with connection established and Channel dropdown populated.
6

Slack Module > Channel > Message Text

Configure Slack channel and message

Select your target Slack channel from the dropdown. For the message text, you'll map data from the Basecamp webhook. Use the mapping panel to insert dynamic content like project name, update title, author, and content. Include the Basecamp URL so team members can click through for details.

  1. 1Select your target channel from the Channel dropdown
  2. 2Click in the Text field to open the mapping panel
  3. 3Map 'Project Name' from Basecamp data
  4. 4Add static text like 'New update in'
  5. 5Map 'Title' and 'Content' fields from the webhook data
What you should see: The message field shows a mix of static text and blue mapped variables from Basecamp.
Common mistake — Basecamp sends HTML in content fields, so you may need text formatting to clean it up for Slack.
Message template

Module Connection > Filter Settings

Add conditional filtering

Click the wrench icon between modules to add a filter. This prevents spam by only sending certain types of updates to Slack. Set conditions like 'event type equals recording' for project updates, or 'todo completed equals true' for finished tasks. Multiple conditions can be combined with AND/OR logic.

  1. 1Click the wrench icon on the line between modules
  2. 2Select 'Set up a filter'
  3. 3Choose 'kind' field from Basecamp data
  4. 4Set condition to 'Text operators > Equal to'
  5. 5Enter 'recording' to only catch project updates
What you should see: A filter icon appears on the connection line with your condition displayed.
Common mistake — Basecamp uses different 'kind' values for different events - check your test data to see the exact strings.

Basecamp > + > Text Formatter > Replace

Format message with rich content

Enhance your Slack message with better formatting using the Text Formatter module. Add this between Basecamp and Slack to clean HTML from Basecamp content, truncate long updates, and format dates properly. This makes notifications more readable in Slack.

  1. 1Add Text Formatter module between Basecamp and Slack
  2. 2Choose 'Replace' operation
  3. 3Map Basecamp content field as input text
  4. 4Set 'Search for' to HTML tags like '<p>|</p>'
  5. 5Leave 'Replace with' empty to strip HTML
What you should see: Text Formatter module processes Basecamp HTML and outputs clean text for Slack.
Common mistake — Test with actual Basecamp content since HTML structure varies between update types.

Scenario > Run Once

Test the complete workflow

Run the scenario end-to-end by creating different types of updates in Basecamp. Try posting a message update, completing a task, and adding a milestone. Check that each triggers the workflow correctly and sends properly formatted messages to your Slack channel.

  1. 1Click 'Run Once' to start the scenario
  2. 2Create a message update in Basecamp
  3. 3Complete a task in the same project
  4. 4Check your Slack channel for both notifications
  5. 5Verify the formatting and content accuracy
What you should see: Your Slack channel receives formatted messages with project name, update type, and clean content from Basecamp.

Scenario Settings > ON/OFF Toggle

Activate and monitor

Turn on the scenario by clicking the ON toggle. Set up error notifications so you know if the webhook fails or Slack messages bounce. Monitor the execution history for the first few days to catch any edge cases with different types of Basecamp content.

  1. 1Click the ON/OFF toggle to activate the scenario
  2. 2Go to Scenario Settings > Error Handling
  3. 3Enable email notifications for errors
  4. 4Set the scenario to run continuously
  5. 5Monitor the History tab for successful executions
What you should see: Scenario shows 'Active' status and begins processing live Basecamp webhooks automatically.
Common mistake — Webhook failures can go unnoticed for hours, so error notifications are essential for production use.

This formula creates smart notification formatting based on the type of Basecamp event, showing different emojis and text for updates vs completed tasks.

Frequently Asked Questions

Common questions about this workflow.

Analysis

VerdictWhy Make for this workflow

Use Make for this if your team needs real-time Basecamp notifications in Slack with custom formatting and filtering. Make's visual builder makes it easy to add conditional logic for different project types, and the text formatting tools clean up Basecamp's HTML content perfectly. Skip Make if you just need basic notifications - Basecamp's native Slack integration might be enough.

Cost

This costs 2 operations per notification - one for the webhook trigger, one for the Slack message. At 50 project updates per day, you're looking at 3,000 operations monthly, which fits comfortably in Make's free 1,000-operation tier if you filter smartly. Zapier would cost $20/month for the same volume since their free tier maxes out at 100 tasks.

Tradeoffs

Zapier's Basecamp integration has more trigger options including specific project filtering, so you don't need separate webhook setups per project. n8n gives you better text processing with full JavaScript for cleaning up Basecamp's messy HTML formatting. Power Automate connects better if your team uses Microsoft Teams instead of Slack. But Make's visual filtering and text formatting modules handle the most common customization needs without code, plus the webhook approach works reliably across all Basecamp account types.

You'll hit Basecamp's webhook quirks where different event types send completely different data structures - completed tasks look nothing like message updates. The HTML cleaning gets tricky because Basecamp sometimes sends malformed HTML that breaks simple regex patterns. Also, if someone reconfigures a Basecamp project's integrations, your webhook disappears without warning and notifications just stop flowing.

Ideas for what to build next

  • Add digest notificationsCreate a second scenario that sends daily summaries of all project activity instead of individual updates.
  • Include file attachmentsExtend the workflow to detect when files are uploaded to Basecamp and include download links in Slack notifications.
  • Route to different channelsAdd logic to send notifications to different Slack channels based on Basecamp project names or client tags.
