Organise Workflows in Reusable Way – Flomenco

Sub-workflows

Flomenco allows you to call one workflow from another, enabling the creation of modular, reusable workflows. This approach significantly enhances maintainability, reusability, and organization. By structuring workflows into smaller, well-defined components, teams can improve collaboration, accelerate onboarding for new developers, and simplify troubleshooting and updates. To implement sub-workflows, use the Execute Workflow and Execute Sub-workflow Trigger nodes.

Creating the Sub-workflow

Create a new workflow.

Add the Execute Sub-workflow Trigger node (also listed under triggers as When Executed by Another Workflow).

Add other nodes to define the sub-workflow’s functionality.

Save the sub-workflow.

Note: The sub-workflow must not contain errors. Otherwise, the parent workflow will fail to trigger it.

Calling the Sub-workflow

Open the workflow where you want to call the sub-workflow.

Add the Execute Sub-workflow node.

Configure the Execute Sub-workflow node to target the desired sub-workflow. You can reference the sub-workflow using “Workflow ID”

Tip: The sub-workflow’s ID is found at the end of its URL.

Provide the required input parameters as defined by the sub-workflow.

Save the workflow.

Once executed, the workflow sends data to the sub-workflow and runs it.

Data Flow Between Workflows

Consider an example where Workflow A calls Workflow B using an Execute Sub-workflow node:

The Execute Sub-workflow node in Workflow A sends data to the Execute Sub-workflow Trigger node in Workflow B.

The final node in Workflow B returns processed data back to Workflow A.

By leveraging modular workflows in Flomenco, teams can improve workflow organization, enhance code reusability, and streamline onboarding for new developers. This approach ensures workflows are scalable, easy to maintain, and adaptable to future changes.
