Master Make.com Scenario Execution Flow

Understanding how scenarios run in make.com is essential if you want predictable, reliable automations. This how-to guide walks you through the complete execution flow, so you can design scenarios that behave exactly as intended, even when they work with multiple records, branches, and errors.

How make.com Executes a Scenario

When you click Run once or your schedule triggers, make.com runs your scenario as a series of operations. Each operation is one successful communication with an app or service, or one internal data-processing step.

The platform processes incoming data in bundles. A bundle is a single unit of data (for example, one Google Sheets row, one email, or one record). The scenario moves each bundle through your modules according to the module configuration and the scenario structure.

Key Terms for Make.com Scenario Flow

Before following the step-by-step walkthrough, review the core terms used in make.com scenario execution:

• Scenario – The entire workflow you design on the canvas.
• Module – A single step, such as a trigger, search, action, iterator, or aggregator.
• Bundle – One item of data processed by the scenario.
• Operation – One completed communication or processing action.
• Execution – One full run of the scenario, from the trigger to the end.

Step-by-Step: How Make.com Processes One Execution

The following steps describe how a typical scenario execution proceeds in make.com from start to finish.

1. Triggering the Scenario in Make.com

Every execution starts with a trigger module. Triggers can be:

• Instant webhooks that react to an event
• Polling triggers that check for new data at intervals
• Manual runs launched with Run once

When the trigger runs, it creates one or more bundles. Each bundle then moves through the scenario independently.

2. Passing Bundles from Module to Module

After the trigger, make.com sends each bundle to the next module in line. For each module:

1. The module reads input from the incoming bundle.
2. It calls an external service or performs an internal function.
3. It outputs one or more new bundles.

If a module returns multiple bundles (for example, a search result with several records), make.com processes each output bundle separately in the following modules.

3. Handling Multiple Bundles in Make.com

Many scenarios work with several items at once. When a module returns multiple bundles, execution follows these rules:

• Bundles are processed in the order they arrive.
• Each bundle completes the entire downstream path before make.com starts the next bundle on that same path.
• Branches and filters can route bundles differently, so not all bundles will necessarily visit all modules.

This behavior helps you reason about the scenario flow and avoid confusion when the same module appears in more than one branch.

Branching and Filters in Make.com Scenarios

Branches and filters control conditional paths. They do not change the fundamentals of how bundles move, but they decide which modules receive each bundle.

4. Using Filters to Route Bundles

Filters on connections define conditions. For each bundle that reaches a connection with a filter:

1. make.com evaluates the condition using values from the bundle.
2. If the condition is true, the bundle continues through that connection.
3. If the condition is false, the bundle stops on that path and does not proceed further there.

You can add multiple branches with different filters to send different types of bundles through different processing steps.

5. Independent Branch Execution in Make.com

When a module sends bundles into multiple branches:

• Each branch processes its bundles independently.
• An error or stop in one branch does not automatically affect the others, unless you configure error handling to do so.
• Bundles may complete branches in different orders, depending on how long downstream modules take.

This design makes it possible to build complex scenarios that, for example, send notifications in one branch and update databases in another.

Error Handling and Stopping Criteria in Make.com

Errors are part of real-world automations. make.com provides flexible error-handling options so you can decide what should happen when something goes wrong.

6. Default Error Behavior

By default, if a module encounters an error for a particular bundle:

• The current bundle fails on that module.
• The execution log shows the error details.
• Other bundles already being processed can continue, unless you configure the opposite.

This means a single failed bundle does not have to stop the entire scenario run.

7. Custom Error Handlers in Make.com

You can also define custom error handlers on modules. Typical responses include:

• Resume the scenario with a fallback value or alternative module.
• Ignore the error and continue.
• Stop the execution completely.
• Route the failed bundle to a dedicated error-handling branch.

By planning these behaviors carefully, you make your make.com scenarios resilient to intermittent API failures and data problems.

Iterators, Aggregators, and Advanced Flow in Make.com

Some modules change how bundles are grouped or split, which affects the scenario flow.

8. Splitting Data with Iterators

An iterator module in make.com takes an array or list and produces one bundle per item. After an iterator:

• Each item becomes its own bundle.
• Downstream modules run once for each bundle.
• You can add filters and branches to treat items differently.

9. Combining Data with Aggregators

An aggregator module does the opposite. It collects multiple bundles and outputs fewer bundles, often just one:

• Batches bundles based on your aggregation settings.
• Waits until all required bundles arrive or conditions are met.
• Produces a new bundle containing a combined array or summary.

This is useful when you want to send a single email with multiple results or post a combined payload to an external system.

How to Predict Scenario Behavior in Make.com

To reliably predict how your scenario will behave in make.com, follow these steps whenever you design or modify a workflow:

1. Map your bundles – Identify where bundles are created, split, and combined.
2. Trace each path – For a sample bundle, list the modules it will visit and in which order.
3. Check filters and branches – Confirm which bundles should pass each filter.
4. Plan error handling – Decide what to do if any module fails for a given bundle.
5. Use Run once – Inspect live bundles and execution logs to confirm that the real behavior matches your design.
