Documentation

n8n-nodes-promptui

npm version

PromptUI's n8n community node — publish to X, Facebook, Instagram, TikTok, and LinkedIn from any n8n workflow, and trigger workflows when PromptUI events fire.

Features

  • Publish action — post to X, Facebook, Instagram, TikTok, or LinkedIn via your connected PromptUI account.
  • Webhook trigger — run a workflow when published or generated events fire. Signature-verified (HMAC SHA-256).
  • Auto-registered webhook — activating a trigger registers a webhook in PromptUI; deactivating deletes it.
  • Platform API key auth — pui_xxx keys generated from the PromptUI dashboard.

Installation

Current distribution status:

  • n8n-nodes-promptui is not yet published to npm.
  • Until npm publication lands, install from a local checkout using the development workflow below.
  • After npm publication, self-hosted n8n operators will be able to install it through Settings → Community Nodes or with npm install n8n-nodes-promptui.
  • Unverified community nodes aren't available on n8n Cloud.

Reviewer readiness

Credentials

Field Value
API Key Your pui_... key (PromptUI dashboard → Settings → API Keys)
Base URL https://www.promptui.co (default)

Nodes

PromptUI (action)

Operation Platforms
Publish X · Facebook · Instagram · TikTok · LinkedIn

Each platform exposes only the fields its endpoint accepts. Errors from the underlying /api/publish/* routes are surfaced as NodeApiError so n8n's retry/continue-on-fail semantics apply.

PromptUI Trigger

Event Fires when…
published /api/publish/* successfully posts to a platform
generated GTM content generation completes

Every incoming webhook is verified against the X-PromptUI-Signature HMAC header. Requests with a bad or missing signature return 401.

Supported platforms

Platform Endpoint Required parameters
X POST /api/publish/x text
Facebook POST /api/publish/facebook pageId, message
Instagram POST /api/publish/instagram igUserId, caption, imageUrls
TikTok POST /api/publish/tiktok body
LinkedIn POST /api/publish/linkedin text
