n8n-nodes-posteverywhere

An n8n community node for PostEverywhere.

Use it to create, schedule and publish social media posts from your n8n workflows. One post can go to Instagram, TikTok, YouTube, LinkedIn, Facebook, X, Threads, Pinterest, Bluesky, Telegram and Discord, and to WordPress as a blog post.

The node calls the PostEverywhere REST API.

Install

In n8n (self-hosted):

1. Go to Settings > Community Nodes.
2. Select Install.
3. Enter n8n-nodes-posteverywhere and confirm.

For other install options, see the n8n community nodes install guide.

Credentials

You need a PostEverywhere account and an API key.

1. Sign in to PostEverywhere and open app.posteverywhere.ai/developers.
2. Create an API key. It starts with pe_live_.
3. In n8n, create a new PostEverywhere API credential and paste the key.
4. Select Save. n8n tests the key by calling GET /me.

The node sends the key as Authorization: Bearer <key>.

Connect your social accounts in the PostEverywhere app first. The node lists the accounts you already connected.

Operations

Post

Fields for Create:

• Content: the post text.
• Account Names or IDs: pick accounts from the list (shown as platform: account name), or pass IDs with an expression, for example {{ [2280, 2291] }}. Optional for drafts.
• Mode and, for Schedule, Scheduled For.
• Additional Fields:
  • Media IDs: comma-separated IDs from Media > Upload From URL.
  • Platform Content (JSON): per-platform overrides, for example {"x": {"content": "Short version"}, "linkedin": {"content": "Longer version"}}. See the platform guides in the API docs.
  • Timezone: an IANA timezone such as Europe/London.

Account

Media

Images are ready at once. Videos import in the background: the response has media_status: "uploading". Wait until the video is ready before you attach it to a post.

Trigger

The PostEverywhere Trigger node starts a workflow when something happens in PostEverywhere.

1. Add the PostEverywhere Trigger node and pick your credential.
2. Choose one or more Events.
3. Activate the workflow. The node creates a webhook in PostEverywhere for this workflow. When you deactivate the workflow, the node deletes the webhook.

Events:

Each run outputs the event as PostEverywhere sends it:

{
	"event": "post.published",
	"event_id": "0f9a2c1e-8b7d-4e6f-a5c4-3b2a1d0e9f8a",
	"created_at": "2026-10-05T14:30:05.000Z",
	"organization_id": "5d1c...",
	"data": {
		"post_id": "7c1e8a52-3f4b-4d6e-9a0b-1c2d3e4f5a6b",
		"destination_id": "d2b4f6a8-1c3e-4a5b-8d7f-9e0a1b2c3d4e",
		"platform": "instagram",
		"account_id": 2280,
		"account_name": "acme.co",
		"published_at": "2026-10-05T14:30:04.000Z",
		"platform_post_url": "https://www.instagram.com/p/C8abcdEFGhi/"
	}
}

Every call is signed. The node checks the X-PostEverywhere-Signature header and rejects calls with a bad signature (HTTP 401).

Your n8n instance must be reachable from the internet. PostEverywhere does not send webhooks to localhost or private network addresses. An organization can have up to 25 webhooks.

Example workflows

1. RSS feed item to LinkedIn and X

Share each new blog article on LinkedIn and X one hour after it appears.

1. RSS Feed Trigger: set the feed URL of your blog.
2. PostEverywhere: Resource Post, Operation Create.
   • Content: New on the blog: {{ $json.title }} {{ $json.link }}
   • Account Names or IDs: pick your LinkedIn and X accounts.
   • Mode: Schedule.
   • Scheduled For: {{ $now.plus(1, 'hour') }}
   • Additional Fields > Platform Content (JSON) (optional, a shorter text for X):
     {{ JSON.stringify({ x: { content: $json.title + ' ' + $json.link } }) }}

Want PostEverywhere to pick the time? Set Mode to Add to Queue instead.

2. Google Sheets row to a post with an image

Plan posts in a sheet with the columns text, image_url, publish_at and account_ids (for example 2280,2291).

1. Google Sheets Trigger: on row added.
2. PostEverywhere: Resource Media, Operation Upload From URL.
   • URL: {{ $json.image_url }}
3. PostEverywhere: Resource Post, Operation Create.
   • Content: {{ $('Google Sheets Trigger').item.json.text }}
   • Account Names or IDs (expression): {{ $('Google Sheets Trigger').item.json.account_ids.split(',') }}
   • Mode: Schedule.
   • Scheduled For: {{ $('Google Sheets Trigger').item.json.publish_at }}
   • Additional Fields > Media IDs: {{ $json.media_id }}

To check the outcome later, add a PostEverywhere node with Post > Get Results and the post ID from step 3.

How the node behaves

• Scheduled times. The API reads a time without an offset as UTC. n8n date fields have no offset. So the node reads such a time in the Timezone field, or in the workflow timezone when that field is empty, and converts it to UTC. A time with an offset or Z is used as is. The time must be in the future.
• Responses. The API wraps every response as { data, error, meta }. The node returns data. List operations return one n8n item per post, account or media item.
• Errors. API errors show the API message, the error code and the request ID. Quote the request ID when you contact support.
• Continue On Fail. When it is on, a failed item returns { "error": "<message>" } and the workflow continues.
• Rate limits and retries. On HTTP 429 the node waits for Retry-After (up to 30 seconds) and tries again, up to 2 times. Server errors (5xx) are retried only for read requests. A create or update is never sent twice, so a post is never duplicated by a retry.
• AI tool. The node can be used as a tool by the n8n AI Agent.

Development

npm install
npm run build   # compile to dist/
npm run lint    # n8n community node lint rules
npm test        # unit tests (mocked HTTP, no API key needed)
npm run dev     # start n8n with this node loaded
