Getting Started with the Make.com Code App

The Make.com Code App lets you write and run JavaScript code directly in your scenarios so you can extend and customize automations without leaving make.com. This how-to guide walks you through enabling the app, creating your first function, and managing code securely.

What is the Make.com Code App?

The Code App is a built-in feature of Make.com that allows you to execute JavaScript as part of your workflows. Instead of relying only on prebuilt modules, you can add custom logic, transform data, and integrate with APIs in a flexible way.

The app works by letting you define JavaScript functions in a dedicated interface, then reuse those functions across one or more scenarios. This helps you centralize logic and avoid duplicating complex steps in multiple automations.

How to Enable the Make.com Code App

The Code App is available directly within your Make.com interface. You do not need a separate account, but you must enable and configure it inside your organization space.

Step 1: Check Availability in Make.com

1. Sign in to your Make.com account in a web browser.
2. Open the organization and team where you build scenarios.
3. Confirm that the Code App option is visible in the left navigation or in the tools or apps section.

If you do not see it, verify that your plan and permissions allow access to advanced features, or contact your organization admin.

Step 2: Open the Make.com Code App

1. From the dashboard, navigate to the area where apps and tools are listed.
2. Click the Code or Code App entry to open the code workspace.
3. Review any introductory information, limits, or usage notes displayed by Make.com for the Code App.

Once open, you will see an interface for managing functions, editing code, and connecting code to scenarios.

Create Your First Function in Make.com

After enabling the Code App, you can define your first JavaScript function. This function can be reused in multiple scenarios in Make.com, which helps you maintain cleaner and more maintainable automations.

Step 3: Add a New Code Function

1. In the Code App interface, select New function or a similar action.
2. Enter a clear name that reflects the function purpose, such as formatDate or calculateTotal.
3. Optionally add a short description to document how the function should be used within Make.com scenarios.

Step 4: Write Your JavaScript Code

1. Use the built-in editor to enter a JavaScript function. For example, you might create a function that:
   • Parses incoming text
   • Transforms JSON data
   • Calculates values for reports
2. Follow any syntax guidelines shown in the editor, including how input variables and outputs must be structured.
3. Make sure to handle errors safely, catching exceptions when needed.

The Code App editor in Make.com is designed for concise, scenario-focused functions. Keep your code small, purposeful, and well commented so other team members can understand it.

Use the Make.com Code App in a Scenario

With a function saved, the next step is to connect it to a live scenario in Make.com so that it can run automatically as part of your workflow.

Step 5: Add the Code App Module to a Scenario

1. Open the Scenarios section in Make.com.
2. Create a new scenario or edit an existing one where you want to run custom code.
3. From the module catalog, search for the Code or Code App module.
4. Drag the module onto the canvas and connect it at the appropriate point in your workflow.

Step 6: Configure the Code Module

1. Select the Code module on the canvas to open its configuration panel.
2. Choose the function you created earlier from the dropdown list.
3. Map input fields from preceding modules to the function parameters defined in the Code App.
4. Review the output mapping so the function outputs are available to the following modules in Make.com.

Once configured, running the scenario will trigger your JavaScript function automatically, using real data from your connected apps.

Test and Debug Your Make.com Code

Reliable automations depend on thoroughly tested code. The Code App inside Make.com provides options to test and validate your functions before using them in production scenarios.

Step 7: Run a Test from the Code App

1. Open the function in the Code App editor.
2. Look for a Run or Test button provided by Make.com.
3. Provide sample input values if prompted.
4. Review the output and any error messages returned by the code.

Adjust your JavaScript until the outputs match your expectations. Testing from the Code App helps you isolate problems before they affect live scenarios.

Step 8: Test in a Live Scenario

1. Return to the scenario using the Code module.
2. Use the Run once feature to execute the flow in Make.com.
3. Inspect the Code module output in the execution log.
4. Verify that downstream modules receive the expected data.

If you see unexpected behavior, refine the function in the Code App and retest. This iterative process ensures stable automations.

Best Practices for the Make.com Code App

Following best practices will help you keep your Make.com projects organized, scalable, and secure.

• Use clear naming: Choose descriptive names for functions so other users in Make.com understand their purpose.
• Keep functions focused: Each function should have a single responsibility, such as validation, transformation, or formatting.
• Document usage: Add comments and descriptions that explain inputs, outputs, and edge cases.
• Handle errors: Use try/catch patterns where appropriate so failures do not break entire scenarios.
• Reuse code: Instead of duplicating logic in multiple modules, centralize it in the Code App and reference the same function across scenarios.

Security and Limits in Make.com Code App

When using the Code App, be aware of the runtime constraints and security practices defined by Make.com.

• Avoid logging or returning sensitive data unnecessarily.
• Respect execution time and memory limits when designing complex operations.
• Use environment variables or secure configuration features for API keys and secrets, if available.
• Review organization-level settings that may affect who can edit or run code.

For the most accurate, up-to-date details on limits and behavior, consult the official documentation.
