There are six categories of blocks in GoLess:

  • General: To conduct a general action within the workflow. For example, make an HTTP request or run another workflow.

  • Browser: To control the browser.

  • Web Interaction: To interact with the active tab of the workflow. Prior to using blocks in this category, you should use a New Tab or Active Tab block.

  • Control Flow: To add logic to the workflow.

  • Online Services: Services that connect to GoLess.

  • Data: Change or manage variables or tables of a workflow.

Block Settings

The blocks are accompanied by a menu and parameters that may be configured.

To find the block menu, place your mouse on a block in the editor's canvas, and it will show up above the block.

  • Delete: remove the block

  • Block settings: open up current block parameters.

  • Move block to group blocks: move the block to the Group blocks by dragging and dropping the icon.

  • Enable/disable block: deactivate block

  • Run: execute the workflow from the active block.

  • Edit: access block properties or click twice on the block.

You can also right-click on the block for more menus.


The Block settings enable you to set up the block execution, error handling, and how it looks like.
