Lambda Input

Lambda Input

What it does: Defines what data your reusable workflow components need to receive from other workflows.

Perfect for: Reusable workflows • Template workflows • Modular design • Data processing pipelines

Simple process: Other workflow calls → Lambda Input receives data → Validates format → Starts your reusable workflow

Common Use Cases

Reusable components - Create workflows that can be used by multiple other workflows Template workflows - Build workflow templates that work with different data Data processing - Create specialized data processing workflows API integration - Standardize how workflows handle external data

Real Example

Scenario: Create a reusable workflow that extracts content from any website URL

Lambda Input Configuration:

{
  "parameterName": "websiteUrl",
  "inputSchema": {
    "type": "object",
    "properties": {
      "url": {"type": "string"},
      "timeout": {"type": "number", "default": 5000}
    },
    "required": ["url"]
  }
}

When another workflow calls this lambda:

{
  "url": "https://news.example.com/article/123",
  "timeout": 10000
}

Lambda Input outputs for your workflow:

{
  "websiteUrl": "https://news.example.com/article/123",
  "timeout": 10000
}

Simple Configuration Tips

Basic text input:

{
  "parameterName": "userText",
  "inputSchema": {"type": "string"}
}

URL with validation:

{
  "parameterName": "websiteUrl",
  "inputSchema": {"type": "string", "format": "uri"}
}

Optional parameters with defaults:

{
  "parameterName": "config",
  "inputSchema": {
    "type": "object",
    "properties": {
      "retries": {"type": "number", "default": 3},
      "timeout": {"type": "number", "default": 5000}
    }
  }
}

Common Workflow Patterns

Simple data processing:

[Lambda Input] → [Process Data] → [Lambda Output]

Web content extraction:

[Lambda Input] → [Get Page Content] → [Extract Text] → [Lambda Output]

AI analysis workflow:

[Lambda Input] → [AI Analysis] → [Format Results] → [Lambda Output]

Quick Troubleshooting

Schema validation fails: Check that the calling workflow sends data in the expected format

Parameter not available: Make sure the parameterName matches what you’re using in other nodes

Workflow won’t start: Verify that all required parameters are being provided
