Step 2: Add Actions: Once the trigger is defined, you can add actions to the workflow. Actions are the individual steps or tasks that need to be performed. They can include updating records, sending notifications, calling APIs, or performing calculations.

Step 3: Configure Actions: Configure each action by specifying the necessary parameters and data inputs. For example, if you are updating a record, you would specify the fields to update and the new values. Flow Designer provides a user-friendly interface for configuring actions without the need for coding.

Step 4: Connect Actions: Connect the actions in the desired sequence by dragging connectors between them. This defines the flow of execution and ensures that actions are performed in the correct order.

Step 5: Define Outputs: If your flow generates outputs or results, define them in the Flow Properties. Outputs can be used to pass data to subsequent actions or to external systems.

Step 6: Test and Validate: Before publishing your flow, it’s essential to test and validate it. Flow Designer provides testing capabilities to simulate the execution of your workflow. This enables you to identify and resolve any issues or errors before deploying it in a live environment.

Step 7: Publish and Activate: Once you are satisfied with your flow, publish and activate it to make it available for use. Published flows can be triggered manually or automatically based on predefined events.

Advanced Flow Design Techniques

Now that you have mastered the basics of Flow Designer, it’s time to explore advanced techniques and best practices for creating efficient and robust workflows. This section will cover various tips and tricks to enhance your flow design skills.

Error Handling

When designing workflows, it’s essential to consider error handling to ensure smooth execution and prevent disruptions. Flow Designer provides several mechanisms for handling errors:

1. Try-Catch Blocks: Use try-catch blocks to encapsulate actions that may generate errors. The try block contains the actions, while the catch block handles any errors that occur. This allows you to define alternative actions or error recovery mechanisms.

2. Error Notifications: Configure error notifications to alert relevant stakeholders when errors occur. This ensures prompt action and enables quick resolution of issues.

3. Error Logging: Implement error logging to capture and store details about errors. This helps in troubleshooting and identifying patterns or recurring issues that may require further investigation.

Parallel Flows

In some scenarios, it may be necessary to execute multiple actions concurrently. Flow Designer supports parallel flows, allowing you to run actions simultaneously. This can significantly improve the performance and efficiency of your workflows.

To create parallel flows, simply drag connectors from a common trigger or action and connect them to separate sets of actions. This enables the actions to be executed in parallel, reducing overall execution time and improving throughput.


Subflows are reusable flow components that can be called from within other flows. They allow you to encapsulate a set of actions and invoke them as a single unit. This promotes code reuse, simplifies flow design, and enhances maintainability.

To create a subflow, design a flow as you would for a regular flow and save it. Then, in the main flow, drag the subflow component from the palette and configure it to call the desired subflow. This enables you to modularize your workflows and create more modular and scalable designs.
