Make.com Best Practices: Build Scenarios That Last in Production

Scenario Organisation

Naming conventions:

Name every Scenario with a consistent pattern:

Folder structure:

• Sales
• Marketing
• Support
• Operations
• Finance

Group related Scenarios in folders. In Make.com, use Teams/Folders to organise.

Active vs Draft: Keep a copy of every Scenario before making significant changes. Right-click → Duplicate. Append " - ARCHIVE" to old versions rather than deleting immediately.

Error Handling

The most overlooked aspect of Make.com Scenarios. Without error handling, failures are silent.

Error routes: Every module can have an error route. Click a module → Add error handler:

• Rollback: Undo all previous module changes in this run (if supported by apps)
• Resume: Skip the failed item and continue with next
• Ignore: Continue from the failed module, as if it succeeded (risky — use carefully)

Recommended pattern for production:

1. Add error route to each critical module
2. Route to: Slack notification + Airtable error log
3. Slack message: "Scenario {{scenario_name}} failed at {{module_name}}: {{error_message}}"

Global scenario error notification: In Scenario settings → Advanced → enable "Email notification on error". Set to immediate for critical Scenarios.

Deduplication

Avoid processing the same record twice.

Data Store method:

1. Before processing: Data Store → Search Records (look for this record's unique ID)
2. Filter: Only continue if record NOT found
3. Process the record
4. After processing: Data Store → Add Record (save the unique ID)

Airtable flag method: Add a boolean field processed to Airtable. When you process a record, set it to true. Trigger/filter only looks at records where processed = false.

Webhook idempotency: Some apps send webhook duplicates. Add an idempotency check: store the event ID in Data Store; skip processing if already seen.

Testing Best Practices

Run with test data first:

1. Set up Scenario but don't activate
2. Use "Run once" button to test with real-but-limited data
3. Verify each module's output before proceeding to the next

Use filters in testing: Add a filter email = test@yourdomain.com or name = "TEST" before activating. This ensures the active Scenario only processes test records while you're building.

Test edge cases:

• What if a required field is empty?
• What if the API is down?
• What if the data has special characters?

Check execution history: Make.com stores execution history. After each test run, review the execution log to see exact data flowing through each module.

Security Best Practices

API keys in connections: Always use Make.com's native connection system for API keys — never hardcode them in HTTP module headers as plain text in the Scenario. If you must use an HTTP module with custom credentials, use Make.com's encrypted custom connections.

Webhook security: For custom webhooks, enable IP filtering (restrict to known sources) or implement signature verification. Without this, anyone who knows your webhook URL can trigger your Scenario.

Data minimisation: Only pass data that each module needs. Don't include PII (personal info) in Slack notifications unless necessary.

Access control: Use Make.com Teams with role-based access. Viewers can see Scenarios but not edit. Don't give everyone admin access.

Performance Optimisation

Reduce module count: Fewer modules = lower operation costs and faster execution. Combine logic where possible.

Use Set Variables module: When you need the same value multiple times downstream, calculate it once with "Set Variables" and reference {{variables.myVar}} throughout.

Parallel execution: Make.com doesn't have native parallel branches. To process multiple items simultaneously, use separate Scenarios triggered from one master Scenario via webhook.

Timeout settings: HTTP module default timeout is 40 seconds. For slow external APIs, increase to 300s. For fast APIs, reducing timeout catches hung requests faster.

Monitoring and Alerting

Weekly health check Scenario:

1. Schedule: every Monday
2. Make.com API: get all active Scenarios
3. Check last run date for each
4. Alert if any Scenario hasn't run in 48+ hours when it should be running hourly
5. Slack: "Scenario health report"

Operation usage monitoring:

1. Schedule: 25th of each month
2. Make.com API: check operation consumption vs limit
3. If > 80% used: Slack alert "Operations at 80% — consider upgrading or optimising"

Error rate tracking: Keep an Airtable error log. Weekly: count errors per Scenario. Any Scenario with >5% error rate needs investigation.

Documentation

Sticky notes in Scenario editor: Add sticky notes (right-click on canvas) to explain complex logic, document assumptions, or note where configuration is required.

Scenario description: Use the Scenario description field (in settings) to note: what it does, what triggers it, what it requires configured, when it was last updated.

Change log in Airtable: Keep a simple Airtable base tracking changes to each Scenario: date, what changed, why. This is invaluable when debugging months later.
