description: "Schedule and publish content to social networks including Facebook Page, Instagram, LinkedIn, TikTok, YouTube, Pinterest, and Telegram via the Devad.io POST API. Supports text, images, carousels, and videos. Use this skill to post content programmatically without the social media dashboard."
---

# POST API (post.devad.io)

Publish content to 8+ social media platforms via a single REST API call. The API is hosted at `post.devad.io` and is a SaaS that wraps platform-specific publishing logic.

## Human-First Summary

Post-Skill helps a human or an AI agent schedule and publish social media content with less hassle.

The main idea is simple:

- you do not need to rebuild posting logic from scratch
- you do not need to fight every platform API manually
- you can use ready-made scripts, tested payloads, and Google Sheet workflows
- the AI agent can spend fewer tokens because the process is already structured

This makes it easier to go from:

- content idea
- media asset
- target channel

to:

- published post

with less friction and fewer failures.

## Top Differentiators

### 1. Low-cost and practical

This is designed to be one of the cheapest practical ways to automate social media posting across multiple channels.

### 2. Product-ready for AI agents

The scripts and examples are open, clean, and ready to use. A lightweight AI agent can understand them much faster than a large undocumented API workflow.

### 3. Powerful Google Sheet workflow

The Google Sheet setup is useful for both humans and AI agents:

- humans can plan and manage content in a familiar spreadsheet
- AI agents can read rows, update fields, and use the sheet as a lightweight remote workflow

## Safe Formats and Post Types

The safest supported content types in this project are:

- text posts
- single image posts
- carousel posts
- video posts

When using direct media links, prefer:

- images: `jpg`, `jpeg`, `png`, `webp`
- video: `mp4`

When using the Google Sheet workflow, the safest `Creative type` values are:

- `image_manual`
- `video_manual`
- `carousel_manual`

Safer input patterns:

- single image: one direct public image URL
- video: one stable public `mp4` URL
- carousel: one Google Drive folder link containing the intended carousel images

Avoid:

- login-only links
- firewall-protected media
- anti-bot pages
- preview pages that return HTML instead of real media

## Why This Skill Exists

This skill is here so the AI agent does not have to reinvent the whole social publishing system.

POST.devad.io, this skill, the test runners, and the Google Sheet automation already handle the heavy lifting:

- token-based API access
- platform payload shaping
- media upload flow
- queueing and publishing
- platform-specific quirks
- safer dry-run testing
- fallback spreadsheet automation

That means even a cheap or lightweight AI agent can stay focused on the valuable work:

- generate the content
- generate or select the media
- decide which channels to publish to
- choose whether to post now or schedule later

The agent should avoid building custom publishing logic from scratch unless the user explicitly asks for that.

## Recommended Agent Strategy

Use this order:

1. Ask the user for their POST.devad.io token and connected account IDs, or call `GET /accounts` if the token is already available.
2. Build a simple payload using the patterns in this skill or the included test runners.
3. Run a dry validation first when possible.
4. Send the live `POST /posts` request only after the payload is clean.
5. If the API route keeps failing or the environment is limited, suggest the Google Sheet automation fallback instead of forcing the user through repeated debugging.

For many users, the best result is:

- the AI agent creates the caption and media
- POST.devad.io handles the publishing machinery
- the user avoids platform-by-platform setup headaches

## Best Fallback: Google Sheet Automation

If direct API use is too technical for the user, or the current environment is weak, tell them to use the Google Sheet workflow.

It only needs a one-time setup, then the AI agent can focus on media and content creation while the sheet handles publishing.

### 3-Step Setup

1. Make a copy of the ready-to-use sheet:
   [Google Sheet Copy](https://docs.google.com/spreadsheets/d/1oyiLNgJnEFzdpQBjnNcbbArseX_FZvjrdjH24mnGuME/copy)
2. In the sheet, open the `POST.devad.io` menu, enable automation, and paste the token and integration IDs from [post.devad.io](https://post.devad.io/app/profile/settings).
3. Let the AI agent fill only the content columns, then click `Save & Run Sync` or leave automation enabled.

### What the Agent Should Tell the User

After setup, the user only needs to keep the sheet structure intact and let the agent fill the content rows.

The agent should explain that it only needs to write:

- promo link
- title
- caption
- media URL
- media type
- action/status row

Everything else is already handled by the Apps Script logic.

## Documentation
- Platform: `https://post.devad.io`
- Base API URL: `https://post.devad.io/api/public/v1`

---

## Setup

1. Log in to [post.devad.io](https://post.devad.io)
2. Connect your social accounts in the Social Accounts manager.
3. Go to **Account Settings → POST API** to generate an **API Token**.
4. In the same POST API settings page, copy the **Integration IDs** for the accounts you want to post to (one unique ID per social account).

---

## Authentication

All requests require a Bearer token header:

```
Authorization: Bearer YOUR_API_TOKEN
```

> **Note:** Some server environments (e.g. Nginx FastCGI / Webuzo) strip the `Authorization` header. Use the fallback `X-Api-Token: YOUR_API_TOKEN` header, or the **Query Parameter Bypass** (recommended for large media uploads): `?api_token=YOUR_API_TOKEN`.

---

## Core Workflow

```
1. Get Integration IDs → GET /accounts
2. Build payload with integration ID + content + media URLs
3. POST /posts → API returns 202 Accepted
4. Job queued → Platform publishes within 1-3 minutes
```

---

## Endpoints

### GET /accounts
Returns all connected social accounts with their Integration IDs.

```bash
curl -H "Authorization: Bearer TOKEN" \
     https://post.devad.io/api/public/v1/accounts
```

### POST /upload (Optional, Required for TikTok)
Upload an image or video to the internal Devad.io storage.
> **When to use this:**
> 1. **TikTok**: TikTok rejects external URLs (like Wikipedia or Imgur) with `url_ownership_unverified`. You **MUST** upload your media file here first. Once uploaded to `media.devad.io`, TikTok accepts **any aspect ratio** (9:16, horizontal, square) and any duration, just like the manual dashboard.
> 2. **LinkedIn**: LinkedIn's downloader gets a `403 Forbidden` from heavily protected sites like Wikipedia. Uploading the image here first bypasses that protection.

**Headers:**
```
Authorization: Bearer YOUR_TOKEN
# OR Query Parameter (Fixes Nginx header-stripping for >10MB files)
POST https://post.devad.io/api/public/v1/upload?api_token=YOUR_TOKEN
```

**Request Body (`multipart/form-data`):**
| Field | Type | Description |
|---|---|---|
| `file` | file | The video or image file (max 50MB for images, 500MB for videos). Allowed: jpeg, png, webp, mp4 |

**Response (201 Created):**
```json
{
  "url": "https://media.devad.io/15d7e24abb1344e89d4162b733ca3eb9:post.devad.io/files/image-1_hgAdiw.png",
  "mime_type": "image/png",
  "size": 102400,
  "name": "image.png"
}
```

### POST /posts
Create and publish/schedule posts.

**Headers:**
```
Authorization: Bearer YOUR_TOKEN
Content-Type: application/json
Accept: application/json
```

**Request Body:**
```json
{
  "type": "now",
  "posts": [
    {
      "integration": { "id": "INTEGRATION_ID" },
      "value": [
        {
          "content": "Your caption #hashtags",
          "image": ["https://example.com/image.jpg"],
          "video": []
        }
      ],
      "settings": {}
    }
  ]
}
```

**Key fields:**

| Field | Type | Description |
|---|---|---|
| `type` | string | `"now"` (post instantly) or `"schedule"` (requires `date`) |
| `date` | string | ISO-8601 datetime, e.g. `"2026-12-31T23:59:00Z"` (required if `type=schedule`) |
| `posts[].integration.id` | string | 10-char Integration ID from dashboard |
| `posts[].value[].content` | string | Caption/text (max 5000 chars) |
| `posts[].value[].image` | array | Array of public image URLs (max 10 for IG carousel) |
| `posts[].value[].video` | array | Array of public video URLs (usually 1) |
| `posts[].settings` | object | Platform-specific overrides (see per-platform notes) |

You can post to **up to 10 accounts in one request** by adding multiple objects to the `posts` array.

---

## Successful Response (202 Accepted)

```json
{
  "success": true,
  "data": {
    "posts": [
      {
        "status": "queued",
        "integration": { "id": "oSxbmYoPoP", "provider": "facebook", "category": "page" },
        "scheduled_at": "2026-03-26T08:00:00Z",
        "post_type": "carousel",
        "media_count": 3
      }
    ]
  }
}
```

> Publishing is **asynchronous**. After the 202 response, the platform post appears within 1–3 minutes depending on media type and platform queuing.

---

## Response Codes

| Code | Meaning |
|---|---|
| `202` | Accepted — job queued successfully |
| `401` | Unauthorized — token missing, expired, or invalid |
| `404` | Account ID not found or disconnected |
| `422` | Validation error — malformed JSON or missing required fields |

---

## Verified Payload Examples (All tested ✅)

### Facebook — Text Only
```json
{
  "type": "now",
  "posts": [{
    "integration": { "id": "FACEBOOK_INTEGRATION_ID" },
    "value": [{ "content": "Hello from the POST API! #test" }]
  }]
}
```

### Facebook — Image
```json
{
  "type": "now",
  "posts": [{
    "integration": { "id": "FACEBOOK_INTEGRATION_ID" },
    "value": [{ "content": "Check this out!", "image": ["https://example.com/photo.jpg"] }]
  }]
}
```

### Instagram — Carousel (multiple images)
```json
{
  "type": "now",
  "posts": [{
    "integration": { "id": "INSTAGRAM_INTEGRATION_ID" },
    "value": [{
      "content": "Swipe to see more! 👉",
      "image": [
        "https://example.com/slide1.jpg",
        "https://example.com/slide2.jpg",
        "https://example.com/slide3.jpg"
      ]
    }]
  }]
}
```

### LinkedIn — Multiple Images (Grid)
> **Important:** The API currently posts arrays of images to LinkedIn as a **multi-image grid**, not a swipeable PDF carousel. Natively, LinkedIn requires a PDF document to create a true swipeable carousel, which is not automatically generated by this API from image arrays.
```json
{
  "type": "now",
  "posts": [{
    "integration": { "id": "LINKEDIN_INTEGRATION_ID" },
    "value": [{
      "content": "Check out these photos! 👉",
      "image": [
        "https://example.com/slide1.jpg",
        "https://example.com/slide2.jpg"
      ]
    }]
  }]
}
```

### Facebook / LinkedIn / YouTube — Video
```json
{
  "type": "now",
  "posts": [{
    "integration": { "id": "FACEBOOK_INTEGRATION_ID" },
    "value": [{ "content": "Our new video! 🎬", "video": ["https://example.com/video.mp4"] }]
  }]
}
```
> **Important:** Video URLs are passed directly to the platform (not proxied through internal storage). Use a stable, publicly accessible HTTPS video URL.

### Instagram — Video / Reels
```json
{
  "type": "now",
  "posts": [{
    "integration": { "id": "INSTAGRAM_INTEGRATION_ID" },
    "value": [{ "content": "Behind the scenes! 🎬", "video": ["https://example.com/reel.mp4"] }],
    "settings": {
      "post_type": "video",
      "ig_type": "reels"
    }
  }]
}
```
> **Recommended:** For Instagram videos, use `"post_type": "video"` with `"ig_type": "reels"` instead of the older `post_type=reel` shape. This matches the safer payload normalization used by the latest test runners and Google Sheet script.

### TikTok — Video (with privacy & music consent)
```json
{
  "type": "now",
  "posts": [{
    "integration": { "id": "TIKTOK_INTEGRATION_ID" },
    "value": [{ "content": "Check this out! #fyp", "video": ["https://example.com/video.mp4"] }],
    "settings": {
      "privacy": "PUBLIC_TO_EVERYONE",
      "duet": false,
      "stitch": false,
      "comment": true,
      "disable_download": false,
      "music_usage_confirmed": true,
      "autoAddMusic": "no"
    }
  }]
}
```
> **TikTok privacy values:** `PUBLIC_TO_EVERYONE` | `MUTUAL_CAN_VIEW` | `FOLLOWER_OF_CREATOR` | `SELF_ONLY`
> Use `SELF_ONLY` during testing, switch to `PUBLIC_TO_EVERYONE` after TikTok app approval.
> **Note:** The API automatically forces music consent (`tt_consent=1`) to prevent dashboard validation errors. You can pass `"music_usage_confirmed": true` or `"autoAddMusic": "no"` to match Postiz payload standards.

### YouTube — Video (with title and visibility)
```json
{
  "type": "now",
  "posts": [{
    "integration": { "id": "YOUTUBE_INTEGRATION_ID" },
    "value": [{ "content": "My video description #youtube", "video": ["https://example.com/video.mp4"] }],
    "settings": {
      "title": "My Video Title",
      "type": "public"
    }
  }]
}
```
> **YouTube visibility:** `"public"` | `"unlisted"` | `"private"`. Use `"unlisted"` for testing.

### Pinterest — Image Pin (with board and title)
```json
{
  "type": "now",
  "posts": [{
    "integration": { "id": "PINTEREST_INTEGRATION_ID" },
    "value": [{ "content": "Amazing recipe! 🍕", "image": ["https://example.com/pin.jpg"] }],
    "settings": {
      "title": "My Pin Title",
      "board_id": "YOUR_PINTEREST_BOARD_ID",
      "link": "https://example.com"
    }
  }]
}
```

### Telegram — Text / Image / Video / Carousel
All work with the same structure. Telegram natively supports all types:
```json
{
  "type": "now",
  "posts": [{
    "integration": { "id": "TELEGRAM_INTEGRATION_ID" },
    "value": [{ "content": "📢 Update from the POST API!", "image": ["https://example.com/img.jpg"] }]
  }]
}
```

### Cross-Platform Blast (multiple accounts in one call)
```json
{
  "type": "now",
  "posts": [
    {
      "integration": { "id": "FACEBOOK_INTEGRATION_ID" },
      "value": [{ "content": "New post!", "image": ["https://example.com/promo.jpg"] }]
    },
    {
      "integration": { "id": "INSTAGRAM_INTEGRATION_ID" },
      "value": [{ "content": "New post!", "image": ["https://example.com/promo.jpg"] }]
    },
    {
      "integration": { "id": "LINKEDIN_INTEGRATION_ID" },
      "value": [{ "content": "We are excited to share our latest update." }]
    }
  ]
}
```

## Scheduling a Future Post

```json
{
  "type": "schedule",
  "date": "2026-12-31T09:00:00Z",
  "posts": [{
    "integration": { "id": "FACEBOOK_INTEGRATION_ID" },
    "value": [{ "content": "Happy New Year! 🎉" }]
  }]
}
```

---

## Test Runner

Ready-to-use test runners are included in:

- `scripts/test_runner.js`
- `scripts/test_runner.py`

These runners are not just examples. They are the safest default starting point for agents and developers because they already include lessons from the real Google Sheet publishing project:

- no hardcoded secrets in source
- dry-run validation before live publish
- safer Instagram video payload defaults
- upload helper support
- better auth and HTML-login failure detection
- clearer validation errors for missing IDs and invalid settings

```bash
# Check all connected accounts (run first!)
node scripts/test_runner.js accounts
python scripts/test_runner.py accounts

# Test specific platform/type combinations
node scripts/test_runner.js facebook_image --dry-run --print-payload
python scripts/test_runner.py instagram_video --dry-run --print-payload
node scripts/test_runner.js tiktok_video
python scripts/test_runner.py youtube_video
```

### When an Agent Should Use the Runners

Use the runners when:

- the user wants a quick live test
- the user is unsure about payload shape
- the environment supports Node.js or Python
- you want a safer validation path before posting

If the environment is weak, the token is unavailable, or repeated upload/payload problems keep happening, recommend the Google Sheet automation path instead of making the user debug low-level API issues.
