n8n-nodes-agentiff

Custom n8n community nodes for Agentiff.AI workflows. Reduces boilerplate in webhook-triggered, SSE-streamed, LLM-powered n8n workflows from ~15 nodes to ~5.

Node Documentation

Agentiff Webhook

Webhook trigger that auto-extracts the standard Agentiff payload structure.

Standard payload (sent by the Agentiff platform):

{
  "execution_id": "exec_abc123",
  "api_token": "sk-...",
  "inputs": { "max_results": 10, "query": "invoice" },
  "credentials": { "gmail": { "access_token": "ya29..." } },
  "prompts": { "system": "...", "user": "..." }
}

Output (with Auto-Extract enabled):

{
  "execution_id": "exec_abc123",
  "api_token": "sk-...",
  "max_results": 10,
  "query": "invoice",
  "_agentiff": {
    "execution_id": "exec_abc123",
    "api_token": "sk-...",
    "base_url": "https://api.agentiff.ai",
    "inputs": { "max_results": 10, "query": "invoice" },
    "credentials": { "gmail": { "access_token": "ya29..." } },
    "prompts": { "system": "...", "user": "..." }
  },
  "body": { /* original body */ }
}

The _agentiff context object is automatically consumed by downstream Agentiff nodes (SSE Event, LLM).

Parameters:

• Path: Webhook URL path
• Response Mode: onReceived, lastNode, or responseNode
• Auto-Extract Standard Fields: Extract and flatten standard payload (default: true)
• Extract Parameters: Additional custom parameters with type conversion and validation

Agentiff SSE Event

Send Server-Sent Events to stream progress updates to Agentiff clients.

Parameters:

• Execution ID: Auto-reads from _agentiff context or execution_id field
• Event Type: progress, status, data, error, complete, or custom
• Event Data: JSON payload

Automatically resolves base_url and api_token from _agentiff context injected by Agentiff Webhook.

Agentiff LLM

Call the Agentiff LLM Gateway (OpenAI-compatible /chat/completions) with built-in response parsing. Replaces the common pattern of HTTP Request + Code node for JSON extraction.

Parameters:

• API Token Source: From Agentiff Context (default) / From Credentials / Custom Expression
• Gateway URL: Defaults to credential base URL. Set ={{ $env.LLM_GATEWAY_URL }} for env-based config.
• Model: gpt-4o-mini, gpt-4o, gpt-4-turbo, gpt-3.5-turbo, Claude 3.5 Sonnet, Claude 3 Haiku, Grok, or Custom
• System Prompt: Optional system prompt (supports expressions)
• User Prompt: Required user prompt
• Response Mode:
  • Text Content: Returns choices[0].message.content as string
  • JSON Extraction (default): Extracts JSON from response with 3-strategy fallback
  • Full Response: Returns complete API response object

JSON extraction strategy (in json mode):

1. Try full content as JSON
2. Try to find JSON array [{...}]
3. Try to find JSON object {...}
4. Falls back to raw text with json_extracted: false

Output (json mode):

{
  "content": "raw LLM text",
  "parsed": { /* extracted JSON object/array */ },
  "json_extracted": true,
  "model": "gpt-4o-mini",
  "usage": { "prompt_tokens": 150, "completion_tokens": 200 }
}

Options: Temperature (0.3), Max Tokens (2000), Top P, Timeout (60s)

Agentiff PII Redact

Detect and redact personally identifiable information from text fields. Supports 15 PII patterns.

Parameters:

• Fields to Scan: Comma-separated field names, supports dot notation (e.g., content, user.email, nested.field)
• PII Types: Multi-select of patterns to detect:

Options:

• Include Findings Summary: Adds pii_redaction object with counts (default: true)
• Passthrough Unscanned Fields: Include unscanned fields in output (default: true)

Agentiff Gmail API

Gmail operations using automatically injected OAuth access tokens.

Operations: List Messages, Get Message, Send Message, Delete Message

Access Token Source:

• From Previous Node: Auto-reads access_token from upstream (e.g., from Agentiff Webhook's _agentiff.credentials)
• Custom Expression: Provide a custom expression

See INSTALLATION.md for detailed Gmail API setup.
