All About ServiceNow Flow Designer

ServiceNow is trying to make things easy for both customers and developers. Customers are getting a better UI day by day, whereas developers or administrators are happy with this new feature of Flow Designer. It is a revolutionary feature that allows you to design things or automate the work without coding and can be reused at any time.

Yes, you heard it right. By using Flow Designer, you can develop most of the stuff in minutes, which previously took time, energy, and coding.

It is the default Now Platform process automation builder that replaces the legacy Workflow graphical editor.

Benefits of Flow Designer

Using ServiceNow’s flow designer comes with so many benefits. Below is a list of a few:

  • Automate repetitive work to improve efficiency and experience
  • Describe a workflow in natural language to help non-technical users understand what it does
  • Display flows as diagrams to help builders see available paths and connections
  • Create and test a workflow from a single interface to ensure it works as expected
  • Promote process automation by enabling subject matter experts to develop and share reusable actions with flow authors
  • Reduce upgrade costs with upgrade-safe Now Platform logic replaces complex custom scripts.
  • Reduce development costs by providing a library of reusable actions
  • Scale with separate subscriptions for integration and Robotic Process Automation (RPA) functionality

Flow Designer components


A flow is an automated process consisting of a trigger and a sequence of reusable actions. The trigger specifies when to run the flow. The actions perform a sequence of operations on your data.

Flow execution details

A flow execution details page allows a flow author to view run-time information about an action or flow directly from the design environment. You can view details such as the current sate, actions or steps run, output values generated, and errors produced.

Flow error handler

A flow error handler enables a flow to catch and report errors from the flow execution details. Run a sequence of actions and subflows to identify and correct issues. For example, have flows log output values, send notifications, and run corrective subflows when they produce an error.


A subflow is an automated process consisting of a sequence of reusable actions, data inputs, and outputs. In contrast to flows, subflows do not have a trigger but instead run when called from a flow, from another subflow, or from a script. Building and managing subflows requires that you have some familiarity with the Now Platform tables and fields that the application or process uses. Process analysts can create subflows using available actions or use an existing subflow as a template.


An action is a reusable operation that enables process analysts to automate Now Platform features without having to write code. For example, the Create Record action allows process analysts to generate records in a particular table with particular values when certain conditions occur.


A spoke is a scoped application containing Flow Designer actions and subflows for managing specific tables. For example, the ITSM Spoke contains actions for managing Incident and Problem records.


A step is a single reusable operation within an action. For example, the Create Record step allows action designers to specify the table and field values to use during record creation.
