What is Flow Designer in ServiceNow?

You can easily create an end-to-end digital workflow. It can be a simple productivity workflow to a complex transformation in a no-code, natural language environment with ServiceNow Flow Designer.

Flow Designer is a ServiceNow feature that allows you to automate business processes in a single design environment without writing any complex code. Also, it allows natural language to automate tasks, approvals, notifications. Flow Designer also supports integration with the external system by using IntegrationHub.

ServiceNow is a cloud-based platform that automates business processes and allows organizations to enhance operational efficiencies by simplifying and automating regular work tasks.

With its beginnings in IT Service Management, ServiceNow has expanded into an Enterprise Service Management platform for businesses, bringing together all business operations such as customer support, HR, security, and more.

Characteristics of Flow | ServiceNow Workflow vs Flow Designer

  • A flow automates that business logic for an application or process.
  • A flow is defined as an automated series of actions that occurs every time a pre-condition is met.
  • A flow is repeatable.
  • A flow executes the same predefined process whenever it runs.

Note: Creating Flow Designer content within a scoped application rather than the "Global" is considered a good design practice.

Flow Designer components

  • Flows:
    • Flow is an automated process that has a sequence of actions and a trigger that automates the business logic for a particular application or process.
  • Subflows:
    • A subflow is an automated process that has a sequence of actions; Still, it takes data inputs that enable the process to start from flow, subflow, or script.
  • Actions:
    • Action is a reusable operation that enables users to automate different features in the ServiceNow platform without writing code.
  • Core actions:
    • Core actions are out-of-the-box actions available in a flow and these actions cannot be editable by the action designer.
  • Action steps:
    • It is a reusable operation within an action.
  • Spokes:
    • A spoke is a scoped application containing Flow Designer content that is dedicated to the application or type of record.
  • Flow Logic:
    • Flow logic is the process where conditions are involved, e.g. If/Else, For Each, Call a Workflow, etc.

Flow Designer vs. Workflow

If you are creating something new, always use Flow Designer. but there are a few circumstances we should still use workflow.

  • The Instance is running on an earlier release than Kingston.
  • Complex process which requires scripted logic, then workflow can be used and call from a flow.
  • Changing logic already developed using Workflow.

Benefits of Flow Designer

  • Flow Designer blends multiple platform automation functions, configurations, and runtime information so that developers and process owners can operate, create, and troubleshoot flows through a single interface.
  • Non-technical users can understand triggers, actions, inputs, and outputs with the help of natural language descriptions. You don't have to script.
  • Flow Designer reduces development costs by providing a library of reusable flow components in the base system which is created by ServiceNow developers.
  • Flow Designer reduces upgrade cost with the help of upgrade-safe platform logic instead of complex custom scripts.
  • We can reuse and share our custom flow components with other Flow Designers.
  • Extend Flow Designer to integrate with external instances and third-party applications with a particular subscription to IntegrationHub.
  • Flow Designer Increase speed of development as users can create actions, flows, and manage flow execution in a single design environment.
