Building a Workflow

  1. Open Workflow page of desired workflow,
  2. Use Open Workflow button to open Workflow Builder and start building.

1. Adding Nodes

To add a Library node (Tool, Script, or Splitter), in Left Sidebar’s Library tab, select node you want to add and drag it into the Canvas.

Let’s see how to add both amass tool and cat-all-in script as a workflow nodes:

2. Connecting Nodes

Library nodes (Tools, Scripts, and Splitters) are connected with each other via data dependencies defined between their inputs and outputs. Data is passed from one node’s output to another node’s input. Both node inputs and outputs are represented by small circles (called “ports”) on the perimeter of the node. Left sided ports represent inputs, right sided ports represent outputs.

Tool Ports Visibility

By default, tool output ports are exposed and visible on canvas, while input ports are partially visible:

Required inputs: Each tool has a set of required inputs to be set for successful

execution. By default, required input ports are visible on canvas and

ready to be utilized.\

Additional inputs: Beside required inputs, each tool has a set of additional inputs

to be set optionally. By default, additional input ports are not

visible on canvas. To utilize any of those inputs, you need to

expose its port in following way:

  1. Single-click on Tool node to open Object Inspector in Right Sidebar,
  2. Find desired input in Disconnected section,
  3. Switch its toggle to ON to expose / visualize it in Canvas.

To connect 2 Library nodes, hover over the output port on the first node and drag it to the desired input port of another node.

Ley’s see how to connect the previously added amass tool and cat-all-in script. We are also adding subfinder. As both amass and subfinder produce files as an output, we can connect them to the cat-all-in script file input.

3. Setting Inputs

Input Nodes

Inputs (parameters) for Tool/Script are defined using Input Nodes - by adding Input Node, connecting Input Node to desired Tool/Script input port, and populating Input Node's value.

1. Single-click on the Tool/Script in the Canvas.
2. In the Object Inspector (Right Sidebar) all possible inputs are listed, divided into 2 sections - Connected inputs and Disconnected inputs:


In this section, all inputs available to be set are listed.

For Tools, additional Show/Hide option is available for each Tool input. Toggle is set on OFF (Hide) by default. By switching displayed toggle on ON (Show), input will be shown in the Canvas and ready to be populated with some value. Once its value is populated, it will be moved from disconnected to connected state.

CONNECTEDIn this section, all populated inputs are listed. For each input, its value is shown within a non-editable box.

3. In the case of Tools, expose the desired Tool’s input port to be visible on the Canvas using the Show/Hide option.

4. Set appropriate Input Node for desired input and populate its value in one of the following ways:

Drag&Drop Input Node Adding (1)

  1. In the Left Sidebar (Inputs tab), according to the type of Library node’s input, find appropriate Input node and add it to Canvas (drag and drop).
  2. Connect it with the Library node by hovering over the port on the Input node and dragging it to the input port of the Library node.
  3. Single-click on the Input node, and set its value in Right Sidebar.

Drag&Pull Input Node Adding (2)

  1. Hover over the input port on the Library node you want to set and drag from port to the empty space in Canvas. Release. Input Node will be created and shown.
  2. Single-click on the Input node, and set its value in Right Sidebar.

Example - setting amass tool inputs

Let’s see how to set up amass tool with domain, with a passive flag (activated with Boolean node) and this resolver file (previously uploaded to Platform using principals from Uploading and using private files).

4. Nodes command line

Click on the Node in Canvas to see its traditional command, at the bottom in CLI’s COMMAND tab.

For Tool Node**, the command shown in CLI's COMMAND tab is **immutable** - it just reflects the selected tool and its parameters to give you a better insight.

For Script Node, the command shown in CLI’s COMMAND tab is editable - script behaviour can be changed.

Bellow, you can see the command for the previously prepared amass tool.

/bin/amass enum -d -passive -rf in/http-input-0/resolvers.txt 
-o out/amass-0/output.txt
