Nested Flows

Nested flows are automation workflows that call or trigger other workflows as part of their execution. In Activepieces, nested flows allow users to create reusable automation components by triggering sub-flows from within a flow, making complex automations easier to manage and scale.

What Are Nested Flows?

Nested flows are workflows embedded inside other workflows. Instead of repeating the same sequence of steps in multiple automations, a single reusable sub-flow can be created and triggered whenever needed.

This concept comes from software engineering, where modularity and reusability are key principles. Just like functions in programming allow developers to reuse code instead of duplicating it, nested flows allow automation designers to reuse components across different workflows.

For example, if multiple workflows require the same process, such as validating customer data or sending a confirmation email, it can be built once as a nested flow and called whenever needed.

In Activepieces, this makes automations cleaner, easier to maintain, and less error-prone.

How Do Nested Flows Work?

Nested flows work by linking one workflow to another. In Activepieces, this process typically looks like:

• Parent flow setup: A primary workflow is created to manage the main process.
• Sub-flow creation: A smaller, reusable workflow is designed to perform a specific task, such as data formatting or approval routing.
• Invocation: The parent flow includes a step that triggers the sub-flow.
• Execution: The sub-flow runs independently, performs its tasks, and returns results (if needed) to the parent flow.
• Reusability: The same sub-flow can be invoked by multiple parent flows, ensuring consistency across processes.

This layered structure makes complex automations modular and scalable.

Why Are Nested Flows Important?

Nested flows are important because they improve reusability, maintainability, and scalability of automations. Without them, automation designers might duplicate the same steps across multiple workflows, leading to inefficiency and increased risk of errors.

The main reasons nested flows matter include:

• Reusability: Build once and reuse across multiple workflows.
• Consistency: Ensure the same process runs identically across different flows.
• Maintainability: Update one sub-flow instead of editing multiple workflows.
• Efficiency: Reduce redundancy by centralizing common processes.
• Scalability: Make it easier to design large, complex automations in modular pieces.

For Activepieces, nested flows are a powerful feature that supports professional-grade automation design. By enabling sub-flows, the platform allows businesses to create modular building blocks for their processes.

Common Use Cases

Nested flows are valuable across many industries and business functions. Examples in Activepieces include:

• Customer support: A parent flow handles ticket intake, while a nested flow validates customer data before routing.
• Sales enablement: A parent flow manages new leads, while a nested flow qualifies them with AI-based scoring.
• Marketing campaigns: A parent flow launches campaigns, while a nested flow handles audience segmentation or email formatting.
• Operations: A parent flow processes invoices, while a nested flow validates vendor details and compliance.
• Finance: A parent flow logs transactions, while a nested flow performs fraud checks.
• HR workflows: A parent flow manages onboarding, while a nested flow handles account provisioning.

These scenarios highlight how nested flows make automations more modular, reusable, and scalable.

FAQs About Nested Flows

What are nested flows in automation?

Nested flows are workflows that trigger other workflows as sub-flows. They make automation modular, allowing common processes to be reused instead of duplicated across multiple workflows.

How are nested flows different from multi-step flows?

Multi-step flows handle multiple actions within a single workflow. Nested flows, on the other hand, call entirely separate workflows as reusable components, making them more modular and easier to maintain.

How does Activepieces support nested flows?

Activepieces supports nested flows by allowing users to trigger sub-flows from within parent flows. This enables the creation of reusable automation components, reducing duplication and improving scalability.
