# Postiz Social Media Scheduler

Direct API integration for social media posting. No n8n workflows needed.

## Quick Reference

| Platform | Integration ID | Character Limit | Handle |
|----------|---------------|-----------------|--------|
| X/Twitter | `YOUR_X_INTEGRATION_ID` | **280** | @YourHandle |
| LinkedIn | `YOUR_LINKEDIN_INTEGRATION_ID` | **3,000** | your-linkedin |
| Bluesky | `YOUR_BLUESKY_INTEGRATION_ID` | **300** | your.bsky.social |

## Platform Content Guidelines

### X/Twitter (280 chars)
- Short, punchy content
- 1-2 hashtags max
- Links count as 23 chars (t.co shortening)
- Threads for longer content (multiple tweets)

### LinkedIn (3,000 chars)
- Professional tone
- Can be longer-form
- Hashtags at end (3-5 recommended)
- First 140 chars show in preview — make them count!

### Bluesky (300 chars)
- Similar to X but slightly more room
- No official hashtag support (use sparingly)
- Growing tech/developer audience

## Authentication

```bash
# Login and save cookie (required before any API call)
curl -s -c /tmp/postiz-cookies.txt \
  'https://your-postiz-instance.com/api/auth/login' \
  -H 'Content-Type: application/json' \
  -d '{"email":"your-email@example.com","password":"your-password","provider":"LOCAL"}'
```

Cookie expires periodically. Re-run login if you get 401 errors.

## Find Next Available Slot

```bash
curl -s -b /tmp/postiz-cookies.txt \
  'https://your-postiz-instance.com/api/posts/find-slot/INTEGRATION_ID'
```

Returns the next open time slot for a given channel. Useful for auto-scheduling without conflicts.

## Upload Media from URL

```bash
curl -s -b /tmp/postiz-cookies.txt \
  'https://your-postiz-instance.com/api/media/upload-from-url' \
  -H 'Content-Type: application/json' \
  -d '{"url": "https://example.com/image.png"}'
```

## Creating Posts

### Schedule a Post (Single Platform)

```bash
curl -s -b /tmp/postiz-cookies.txt \
  'https://your-postiz-instance.com/api/posts' \
  -H 'Content-Type: application/json' \
  -d '{
    "type": "schedule",
    "date": "2026-02-05T15:00:00Z",
    "posts": [{
      "integration": {"id": "YOUR_X_INTEGRATION_ID"},
      "value": [{"content": "Your tweet here (max 280 chars)", "image": []}],
      "settings": {"__type": "x"}
    }]
  }'
```

### Multi-Platform Post (Adapted Content)

```bash
curl -s -b /tmp/postiz-cookies.txt \
  'https://your-postiz-instance.com/api/posts' \
  -H 'Content-Type: application/json' \
  -d '{
    "type": "schedule",
    "date": "2026-02-05T15:00:00Z",
    "posts": [
      {
        "integration": {"id": "YOUR_X_INTEGRATION_ID"},
        "value": [{"content": "Short X version (280 chars max)", "image": []}],
        "settings": {"__type": "x"}
      },
      {
        "integration": {"id": "YOUR_LINKEDIN_INTEGRATION_ID"},
        "value": [{"content": "Longer LinkedIn version with more context and professional tone. Can be up to 3000 characters.", "image": []}],
        "settings": {"__type": "linkedin"}
      },
      {
        "integration": {"id": "YOUR_BLUESKY_INTEGRATION_ID"},
        "value": [{"content": "Bluesky version (300 chars max)", "image": []}],
        "settings": {"__type": "bluesky"}
      }
    ]
  }'
```

### Post Types
- `schedule` — Auto-publish at specified date/time
- `draft` — Save for review (won't auto-publish)
- `now` — Publish immediately

## Listing & Querying Posts

### Get Posts by Date Range (Required!)
```bash
curl -s -b /tmp/postiz-cookies.txt \
  'https://your-postiz-instance.com/api/posts?startDate=2026-02-01T00:00:00Z&endDate=2026-02-08T00:00:00Z' \
  | jq '.posts[] | {id, state, publishDate, platform: .integration.providerIdentifier, content: .content[0:60]}'
```

### Check for Duplicates Before Posting
```bash
# Get recent posts and check content similarity
curl -s -b /tmp/postiz-cookies.txt \
  'https://your-postiz-instance.com/api/posts?startDate=2026-02-01T00:00:00Z&endDate=2026-02-08T00:00:00Z' \
  | jq -r '.posts[] | "\(.integration.providerIdentifier): \(.content[0:80])"'
```

## Post States

| State | Description |
|-------|-------------|
| `QUEUE` | Scheduled, waiting to publish |
| `PUBLISHED` | Successfully posted |
| `ERROR` | Failed to publish |
| `DRAFT` | Saved but not scheduled |

## Media Upload

### Upload Image
```bash
# Upload returns {id, path}
curl -s -b /tmp/postiz-cookies.txt \
  'https://your-postiz-instance.com/api/media/upload-simple' \
  -F 'file=@/path/to/image.png'
```

### Use in Post
```json
"value": [{
  "content": "Post with image",
  "image": [{"id": "MEDIA_ID", "path": "/uploads/..."}]
}]
```

## Twitter/X Threads

For longer content on X, create a thread:

```json
"value": [
  {"content": "Tweet 1/3: Introduction to the topic...", "image": []},
  {"content": "Tweet 2/3: The main point explained...", "image": []},
  {"content": "Tweet 3/3: Conclusion and call to action.", "image": []}
]
```

## Managing Posts

### Delete Post
```bash
curl -s -b /tmp/postiz-cookies.txt -X DELETE \
  'https://your-postiz-instance.com/api/posts/POST_ID'
```

### Update Schedule
```bash
curl -s -b /tmp/postiz-cookies.txt -X PUT \
  'https://your-postiz-instance.com/api/posts/POST_ID/date' \
  -H 'Content-Type: application/json' \
  -d '{"date": "2026-02-06T10:00:00Z"}'
```

## Best Practices

### Avoid Duplicates
1. Always query existing posts before creating new ones
2. Use unique identifiers in content (dates, specific references)
3. Check both QUEUE and PUBLISHED states

### Scheduling
- Space posts at least 2-4 hours apart per platform
- Best times: 9 AM, 12 PM, 5 PM (audience timezone)
- Avoid posting same content to all platforms simultaneously

### Content Adaptation
Don't just truncate! Rewrite for each platform:
- **X**: Hook + key insight + CTA
- **LinkedIn**: Context + value + engagement question
- **Bluesky**: Casual tech-friendly tone

## Helper Script

Use `scripts/post.py` for easier posting with automatic character validation:

```bash
# Single platform
~/.local/bin/uv run ~/clawd/skills/postiz/scripts/post.py \
  --platform x \
  --content "Your tweet here" \
  --schedule "2026-02-05T15:00:00Z"

# Multi-platform with different content
~/.local/bin/uv run ~/clawd/skills/postiz/scripts/post.py \
  --x "Short X version" \
  --linkedin "Longer LinkedIn version with more detail" \
  --bluesky "Bluesky version" \
  --schedule "2026-02-05T15:00:00Z"
```

## Troubleshooting

### 401 Unauthorized
Re-run the login curl command to refresh cookie.

### Post Not Publishing
1. Check state is `QUEUE` not `DRAFT`
2. Verify date is in the future
3. Check integration is still connected in UI

### Duplicate Posts
Always check existing posts before creating. The API doesn't deduplicate automatically.
