Base64Decode Step

Use this step to decode base64 text.

Last published at: December 28th, 2023


This step convert base64 text to a decoded string.



  • stringText – Text to decode
  • variableToStoreValue –  Variable to store the value



  • True – step executed successfully
  • False – step failed to execute






Let’s build and execute the Base64decodeDef example.

  • Create a new definition called “Base64decodeDef”
  • Select the definition and click the “design” button
  • Drag a “base64Encode” and “base64Decpde” step to the canvas
  • Connect the dots between the Start, base64Encode and base64Decode steps
  • Click on the “base64Encode” step to configure its “Settings” properties. Provide a name to the step. Provide a text string to encode. Provide a variable/global to store the value. 
  • Click on the “base64Decode” step to configure its “Settings” properties. Provide a variable/global having the text to decode. Provide a variable/global to store the decoded value. 
  • The “Logging” setting configuration is necessary for documentation and also measure the workflow progress and the percent complete. This is acheived by configuring the step state and percent fields individually as shown in the images below. Configure the “Logging” using the following properties.
  • Save the process definition, create a new process instance and execute. Render the process instance. Click on the process step to view the properties. The step should encode and decode the text and store the result in the variable/global.
