n8n community node for Latitude. run versioned LLM prompts, continue multi-turn conversations, and push external logs back into Latitude — all from n8n workflows.

# in n8n: settings > community nodes
n8n-nodes-latitude

three operations, all working per-item across your n8n workflow:

• run prompt — execute a Latitude prompt by path, with dynamic parameters extracted from {{ variable }} placeholders. supports version pinning and custom identifiers
• chat — continue a multi-turn conversation using the conversationUuid from a previous run
• create log — push externally-generated conversations into Latitude for observability

also works as an AI agent tool — drop it into n8n's agent node and let the LLM call Latitude prompts dynamically.

settings > community nodes > install n8n-nodes-latitude

cd /path/to/n8n
npm install n8n-nodes-latitude
# restart n8n

create Latitude API credentials in n8n with:

select a prompt from the dropdown (fetched live from your Latitude project). parameters are auto-detected from {{ placeholder }} syntax in the prompt content and presented as a dynamic dropdown.

options:

• custom identifier — tag the run for filtering in Latitude dashboard
• version UUID — pin to a specific prompt version instead of live

pass the conversationUuid from a previous run result, plus one or more messages with role (user / assistant / system) and content.

select a prompt path, provide the conversation messages, and optionally include the AI response text. useful for logging conversations that happened outside Latitude.

enabled by default. strips the full conversation history and returns:

{
  "uuid": "conversation-uuid",
  "text": "model response",
  "usage": { "promptTokens": 150, "completionTokens": 42, "totalTokens": 192 },
  "cost": 0.0023,
  "toolCalls": [{ "id": "...", "name": "...", "arguments": {} }]
}

disable simplify to get the raw SDK response including full conversation array.

• per-item error isolation — if continueOnFail is enabled in n8n, failed items return { error, errorCode, status } instead of halting the workflow
• API keys are automatically redacted from error messages before they reach n8n logs

pnpm install
pnpm build          # tsc + gulp (copies icons to dist/)
pnpm lint           # eslint
pnpm format         # prettier

output goes to dist/. only dist/ is published to npm.
