### Get Posts by Date Range (Required!)

curl -s -b /tmp/postiz-cookies.txt \\
  "$POSTIZ_URL/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]}'

curl -s -b /tmp/postiz-cookies.txt \\
  "$POSTIZ_URL/api/posts?startDate=2026-02-01T00:00:00Z&endDate=2026-02-08T00:00:00Z" \\
  | jq -r '.posts[] | "\\(.integration.providerIdentifier): \\(.content[0:80])"'

StateDescriptionQUEUEScheduled, waiting to publishPUBLISHEDSuccessfully postedERRORFailed to publishDRAFTSaved but not scheduled

  {"content": "Tweet 2/3: The main point explained...", "image": []},
  {"content": "Tweet 3/3: Conclusion and call to action.", "image": []}

  -H 'Content-Type: application/json' \\

### Avoid Duplicates

Always query existing posts before creating new ones
Use unique identifiers in content (dates, specific references)
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

### Post to Multiple Platforms

# Single platform
uv run scripts/post.py \\
  --platform x \\
  --content "Your tweet here" \\
  --schedule "2026-02-05T15:00:00Z"

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

# Post immediately
uv run scripts/post.py \\
  --platform x \\
  --content "Posting now!" \\
  --now

# Validate without posting
uv run scripts/post.py \\
  --x "Test content" \\
  --validate

### Check for Duplicates

# Check last 30 days
uv run scripts/check_duplicates.py

# Check last 7 days
uv run scripts/check_duplicates.py --days 7

# Check if specific content would be duplicate
uv run scripts/check_duplicates.py --content "Your proposed post content"

### 401 Unauthorized

Re-run the login curl command to refresh cookie.

### Post Not Publishing

Check state is QUEUE not DRAFT
Verify date is in the future
Check integration is still connected in UI

### Duplicate Posts

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

export POSTIZ_URL="https://your-postiz.example.com"
export POSTIZ_EMAIL="your@email.com"
export POSTIZ_PASSWORD="your-password"
export POSTIZ_X_ID="your-integration-id"
