Node Configuration

There are two types of nodes in the workflow editor:

1. Custom Node: Create your own node by providing the node function and the UI schema.
   • Use AI to create Custom Node
2. Template Nodes: Select pre-defined nodes that you can directly use as part of your workflow

There are several configurations available for nodes in the workflow editor.

1. Input Configuration

• Input Mappings (Define how data flows into the node)

  Each input mapping has:

  1. Name: The parameter name in the node function
  2. Variable Type: How the input is provided
     • USER_INPUT: Value provided by user through UI
     • WORKFLOW_VARIABLE: Value from another node's output
     • CONSTANT: Fixed value defined at node creation
     • IGNORE: Input is ignored, useful for template nodes where you can't delete the existing inputs
  3. Source Node: For workflow variables, specifies which node provides the value. A node can take inputs from any ancestor node, not just the predecessor node.
  4. Output Name: For workflow variables, specifies the output name of the source node
  5. Required: For user inputs, whether the input is mandatory to be provided by the user

• Input Schema (Configure UI)

  • Customize the UI form for user inputs using JSON and UI Schema. Refer JSON Schema Playground for AI Agents for more details.
  • Supports: Text fields, File uploads, Checkboxes, Radio buttons, Dropdowns, Number inputs, Date inputs

2. Node Source Code (function) Configuration

• Node Function Name: Name of the Python function implementing the node's logic
• Source Code: The actual Python code for the node's function, which will be executed when the node is run. Use the abacusai module to interact with the Abacus.AI platform.

3. Output Configuration

• Output Mappings

  Define what data the node produces. Each output has:

  • Name: Identifier for the output value
  • Variable Type: The data type of the output. Examples: STRING, INTEGER, ATTACHMENT, BOOLEAN, ANY
  • Display in UI: Whether the output should be displayed in the UI

Advanced Configurations

• Template Configuration (When using node templates)

  • Template Name: Identifier for the template being used
  • Configs: Template-specific configuration values

• Trigger Configuration (For nodes that act as workflow triggers)

  • Sleep Time: Time in seconds to wait before re-executing the workflow (for periodic triggers)
