# Facebook Post

<!-- meta: type=facebook-post; location=Social › Facebook; category=Step (action); platforms=Joomla and WordPress (where applicable) -->

## Overview

Facebook Post is a **Step (action)** in **Social › Facebook**. Publishes a text post, link post, or photo to a Facebook Page via Graph API.

When the flow reaches this step, JOrchestrator executes **Facebook Post** against your linked site or an external integration, using the field values you set on **General** and **Design**. Downstream steps can read the output payload fields defined for this node.

## Why use this node

Facebook Post is a **action step** in the **Social › Facebook** group. Action steps run in the middle or end of a flow. They perform work on your CMS, call external services, or transform data for the next step.

Typical reasons teams add **Facebook Post** to a flow:

- Automate "Facebook Post" as part of a larger Joomla or WordPress workflow
- Replace manual facebook work with a repeatable, logged flow step
- Chain with triggers, logic, and messaging nodes on the same canvas

## Example workflows

Common patterns on the canvas:

1. **Trigger or Webhook** → upstream steps → **Facebook Post** → **Send Email** or CMS update
2. **Scheduled trigger** → **Facebook Post** → **Debug** (while testing) → production action

## How to set it up

Page ID and Page access token in Node Configuration → Facebook. Message, Link, and/or Photo source on the Design tab.

## Good to know

Photo URLs use the /photos endpoint; binary/base64 uploads use multipart. Link posts require a public https URL.

## Properties panel

The designer shows these tabs for this node:

| Tab | Purpose |
|-----|---------|
| **Info** | Plain-language description and output payload fields for downstream steps |
| **General** | Canvas label and read-only node ID |
| **AI** | Optional assistant to help draft settings from plain language |
| **Design** | Node-specific configuration fields |

### System (automatic — not edited by the user)

These fields are managed by the designer or runtime — you do not type into them directly:

| Property key | Label | Type | Required | Visible when | Notes |
|--------------|-------|------|----------|--------------|-------|
| `_nodeId` | Node ID | `node-id` | No | — | — |
| `_payloadFields` | Available Fields | `payload-panel` | No | — | — |

### User-configured — General tab

| Property key | Label | Type | Required | Visible when | Notes |
|--------------|-------|------|----------|--------------|-------|
| `label` | Label | `text` | No | — | Node label |

### User-configured — Design tab

| Property key | Label | Type | Required | Visible when | Notes |
|--------------|-------|------|----------|--------------|-------|
| `pageId` | Page ID (optional) | `payload-text` | No | — | Uses Joomla Node Configuration → Facebook default Page ID if empty |
| `message` | Message | `textarea` | No | — | Post text or {{node.caption}} |
| `link` | Link (optional) | `payload-text` | No | — | https://example.com/article Public https URL for a link preview post. Ignored when Photo source is set. |
| `photoSource` | Photo source (optional) | `textarea` | No | — | https://… or data:image/*;base64,… — publishes via /photos |

### CMS site configuration (not on this node's properties panel)

Credentials, API keys, mailers, SMTP, and integration defaults are configured in the CMS plugin under **Node Configuration**, not per step on this node. Link the flow to a domain before testing CMS-backed fields.

## Output payload fields

After this step runs, later nodes can reference these fields using placeholders such as
`{{facebook_post.success}}`.

| Field key | Type | Description |
|-----------|------|-------------|
| `success` | boolean | Whether the operation completed successfully. |
| `postId` | string | Text value from this node's output. |
| `message` | string | Human-readable status, error, or result summary. |
