Core Workflow
The fundamental pattern for using Postiz CLI:
1. Discover - List integrations and get their settings
2. Fetch - Use integration tools to retrieve dynamic data (flairs, playlists, companies)
3. Prepare - Upload media files if needed
4. Post - Create posts with content, media, and platform-specific settings
5. Analyze - Track performance with platform and post-level analytics
6. Resolve - If analytics returns {"missing": true}, run posts:missing to list provider content, then posts:connect to link it
1. Discover
postiz integrations:list
postiz integrations:settings <integration-id>
2. Fetch (if needed)
postiz integrations:trigger <integration-id> <method> -d '{"key":"value"}'
3. Prepare
postiz upload image.jpg
4. Post
postiz posts:create -c "Content" -m "image.jpg" -i "<integration-id>"
5. Analyze
postiz analytics:platform <integration-id> -d 30
postiz analytics:post <post-id> -d 7
6. Resolve (if analytics returns {"missing": true})
postiz posts:missing <post-id>
postiz posts:connect <post-id> --release-id "<content-id>"

Creating Posts
Simple post (date is REQUIRED)
postiz posts:create -c "Content" -s "2024-12-31T12:00:00Z" -i "integration-id"
Draft post
postiz posts:create -c "Content" -s "2024-12-31T12:00:00Z" -t draft -i "integration-id"
Post with media
postiz posts:create -c "Content" -m "img1.jpg,img2.jpg" -s "2024-12-31T12:00:00Z" -i "integration-id"
Post with comments (each with own media)
postiz posts:create \
-c "Main post" -m "main.jpg" \
-c "First comment" -m "comment1.jpg" \
-c "Second comment" -m "comment2.jpg,comment3.jpg" \
-s "2024-12-31T12:00:00Z" \
-i "integration-id"
Multi-platform post
postiz posts:create -c "Content" -s "2024-12-31T12:00:00Z" -i "twitter-id,linkedin-id,facebook-id"
Platform-specific settings
postiz posts:create \
-c "Content" \
-s "2024-12-31T12:00:00Z" \
--settings '{"subreddit":[{"value":{"subreddit":"programming","title":"My Post","type":"text"}}]}' \
-i "reddit-id"
Complex post from JSON file
postiz posts:create --json post.json
Managing Posts
List posts (defaults to last 30 days to next 30 days)
postiz posts:list
List posts in date range
postiz posts:list --startDate "2024-01-01T00:00:00Z" --endDate "2024-12-31T23:59:59Z"
Delete post
postiz posts:delete <post-id>
Analytics
Get platform analytics (default: last 7 days)
postiz analytics:platform <integration-id>
Get platform analytics for last 30 days
postiz analytics:platform <integration-id> -d 30
Get post analytics (default: last 7 days)
postiz analytics:post <post-id>
Get post analytics for last 30 days
postiz analytics:post <post-id> -d 30
Returns an array of metrics (e.g. Followers, Impressions, Likes, Comments) with daily data points and percentage change over the period.
⚠️ IMPORTANT: Missing Release ID HandlingIf analytics:post returns {"missing": true} instead of an analytics array, the post was published but the platform didn't return a usable post ID. You must resolve this before analytics will work:
1. analytics:post returns {"missing": true}
postiz analytics:post <post-id>
2. Get available content from the provider
postiz posts:missing <post-id>
Returns: [{"id": "7321456789012345678", "url": "https://...cover.jpg"}, ...]
3. Connect the correct content to the post
postiz posts:connect <post-id> --release-id "7321456789012345678"
4. Now analytics will work
postiz analytics:post <post-id>
Connecting Missing Posts
Some platforms (e.g. TikTok) don't return a post ID immediately after publishing. When this happens, the post's releaseId is set to "missing" and analytics are unavailable until resolved.
List recent content from the provider for a post with missing release ID
postiz posts:missing <post-id>
Connect a post to its published content
postiz posts:connect <post-id> --release-id "<content-id>"
Returns an empty array if the provider doesn't support this feature or if the post doesn't have a missing release ID.
Media Upload
⚠️ IMPORTANT: Always upload files to Postiz before using them in posts. Many platforms (TikTok, Instagram, YouTube) require verified URLs and will reject external links.Upload file and get URL
postiz upload image.jpg
Supports: images (PNG, JPG, GIF, WEBP, SVG), videos (MP4, MOV, AVI, MKV, WEBM),
audio (MP3, WAV, OGG, AAC), documents (PDF, DOC, DOCX)
Workflow: Upload → Extract URL → Use in post
VIDEO=$(postiz upload video.mp4)
VIDEO_PATH=$(echo "$VIDEO" | jq -r '.path')
postiz posts:create -c "Content" -s "2024-12-31T12:00:00Z" -m "$VIDEO_PATH" -i "tiktok-id"
---
Common Patterns
Pattern 1: Discover & Use Integration Tools
Reddit - Get flairs for a subreddit:Get Reddit integration ID
REDDIT_ID=$(postiz integrations:list | jq -r '.[] | select(.identifier=="reddit") | .id')
Fetch available flairs
FLAIRS=$(postiz integrations:trigger "$REDDIT_ID" getFlairs -d '{"subreddit":"programming"}')
FLAIR_ID=$(echo "$FLAIRS" | jq -r '.output[0].id')
Use in post
postiz posts:create \
-c "My post content" \
-s "2024-12-31T12:00:00Z" \
--settings "{\"subreddit\":[{\"value\":{\"subreddit\":\"programming\",\"title\":\"Post Title\",\"type\":\"text\",\"is_flair_required\":true,\"flair\":{\"id\":\"$FLAIR_ID\",\"name\":\"Discussion\"}}}]}" \
-i "$REDDIT_ID"
YouTube - Get playlists:
YOUTUBE_ID=$(postiz integrations:list | jq -r '.[] | select(.identifier=="youtube") | .id')
PLAYLISTS=$(postiz integrations:trigger "$YOUTUBE_ID" getPlaylists)
PLAYLIST_ID=$(echo "$PLAYLISTS" | jq -r '.output[0].id')
postiz posts:create \
-c "Video description" \
-s "2024-12-31T12:00:00Z" \
--settings "{\"title\":\"My Video\",\"type\":\"public\",\"playlistId\":\"$PLAYLIST_ID\"}" \
-m "video.mp4" \
-i "$YOUTUBE_ID"
LinkedIn - Post as company:
LINKEDIN_ID=$(postiz integrations:list | jq -r '.[] | select(.identifier=="linkedin") | .id')
COMPANIES=$(postiz integrations:trigger "$LINKEDIN_ID" getCompanies)
COMPANY_ID=$(echo "$COMPANIES" | jq -r '.output[0].id')
postiz posts:create \
-c "Company announcement" \
-s "2024-12-31T12:00:00Z" \
--settings "{\"companyId\":\"$COMPANY_ID\"}" \
-i "$LINKEDIN_ID"
Pattern 2: Upload Media Before Posting
Upload multiple files
VIDEO_RESULT=$(postiz upload video.mp4)
VIDEO_PATH=$(echo "$VIDEO_RESULT" | jq -r '.path')
THUMB_RESULT=$(postiz upload thumbnail.jpg)
THUMB_PATH=$(echo "$THUMB_RESULT" | jq -r '.path')
Use in post
postiz posts:create \
-c "Check out my video!" \
-s "2024-12-31T12:00:00Z" \
-m "$VIDEO_PATH" \
-i "tiktok-id"
Pattern 3: Twitter Thread
postiz posts:create \
-c "🧵 Thread starter (1/4)" -m "intro.jpg" \
-c "Point one (2/4)" -m "point1.jpg" \
-c "Point two (3/4)" -m "point2.jpg" \
-c "Conclusion (4/4)" -m "outro.jpg" \
-s "2024-12-31T12:00:00Z" \
-d 2000 \
-i "twitter-id"
Pattern 4: Multi-Platform Campaign
Create JSON file with platform-specific content
cat > campaign.json << 'EOF'
{
"integrations": ["twitter-123", "linkedin-456", "facebook-789"],
"posts": [
{
"provider": "twitter",
"post": [
{
"content": "Short tweet version #tech",
"image": ["twitter-image.jpg"]
}
]
},
{
"provider": "linkedin",
"post": [
{
"content": "Professional LinkedIn version with more context...",
"image": ["linkedin-image.jpg"]
}
]
}
]
}
EOF
postiz posts:create --json campaign.json
Pattern 5: Validate Settings Before Posting
#!/bin/bash
INTEGRATION_ID="twitter-123"
CONTENT="Your post content here"
Get integration settings and extract max length
SETTINGS_JSON=$(postiz integrations:settings "$INTEGRATION_ID")
MAX_LENGTH=$(echo "$SETTINGS_JSON" | jq '.output.maxLength')
Check character limit and truncate if needed
if [ ${#CONTENT} -gt "$MAX_LENGTH" ]; then
echo "Content exceeds $MAX_LENGTH chars, truncating..."
CONTENT="${CONTENT:0:$((MAX_LENGTH - 3))}..."
fi
Create post with settings
postiz posts:create \
-c "$CONTENT" \
-s "2024-12-31T12:00:00Z" \
--settings '{"key": "value"}' \
-i "$INTEGRATION_ID"
Pattern 6: Batch Scheduling
#!/bin/bash
Schedule posts for the week
DATES=(
"2024-02-14T09:00:00Z"
"2024-02-15T09:00:00Z"
"2024-02-16T09:00:00Z"
)
CONTENT=(
"Monday motivation 💪"
"Tuesday tips 💡"
"Wednesday wisdom 🧠"
)
for i in "${!DATES[@]}"; do
postiz posts:create \
-c "${CONTENT[$i]}" \
-s "${DATES[$i]}" \
-i "twitter-id" \
-m "post-${i}.jpg"
echo "Scheduled: ${CONTENT[$i]} for ${DATES[$i]}"
done
Pattern 7: Error Handling & Retry
#!/bin/bash
CONTENT="Your post content"
INTEGRATION_ID="twitter-123"
DATE="2024-12-31T12:00:00Z"
MAX_RETRIES=3
for attempt in $(seq 1 $MAX_RETRIES); do
if postiz posts:create -c "$CONTENT" -s "$DATE" -i "$INTEGRATION_ID"; then
echo "Post created successfully"
break
else
echo "Attempt $attempt failed"
if [ "$attempt" -lt "$MAX_RETRIES" ]; then
DELAY=$((2 ** attempt))
echo "Retrying in ${DELAY}s..."
sleep "$DELAY"
else
echo "Failed after $MAX_RETRIES attempts"
exit 1
fi
fi
done

Technical Concepts
Integration Tools Workflow
Many integrations require dynamic data (IDs, tags, playlists) that can't be hardcoded. The tools workflow enables discovery and usage:
1. Check available tools - integrations:settings returns a tools array
2. Review tool schema - Each tool has methodName, description, and dataSchema
3. Trigger tool - Call integrations:trigger with required parameters
4. Use output - Tool returns data to use in post settings
Example tools by platform:- -Reddit:
getFlairs,searchSubreddits,getSubreddits - -YouTube:
getPlaylists,getCategories,getChannels - -LinkedIn:
getCompanies,getOrganizations - -Twitter/X:
getListsowned,getCommunities - -Pinterest:
getBoards,getBoardSections
Provider Settings Structure
Platform-specific settings use a discriminator pattern with __type field:
{
"posts": [
{
"provider": "reddit",
"post": [{ "content": "...", "image": [...] }],
"settings": {
"__type": "reddit",
"subreddit": [{
"value": {
"subreddit": "programming",
"title": "Post Title",
"type": "text",
"url": "",
"is_flair_required": false
}
}]
}
}
]
}
Pass settings directly:
postiz posts:create -c "Content" -s "2024-12-31T12:00:00Z" --settings '{"subreddit":[...]}' -i "reddit-id"
Backend automatically adds "__type" based on integration ID
Comments and Threading
Posts can have comments (threads on Twitter/X, replies elsewhere). Each comment can have its own media:
Using multiple -c and -m flags
postiz posts:create \
-c "Main post" -m "image1.jpg,image2.jpg" \
-c "Comment 1" -m "comment-img.jpg" \
-c "Comment 2" -m "another.jpg,more.jpg" \
-s "2024-12-31T12:00:00Z" \
-d 5 \ # Delay between comments in minutes
-i "integration-id"
Internally creates:
{
"posts": [{
"value": [
{ "content": "Main post", "image": ["image1.jpg", "image2.jpg"] },
{ "content": "Comment 1", "image": ["comment-img.jpg"], "delay": 5 },
{ "content": "Comment 2", "image": ["another.jpg", "more.jpg"], "delay": 5 }
]
}]
}
Date Handling
All dates use ISO 8601 format:
- -Schedule posts:
-s "2024-12-31T12:00:00Z" - -List posts:
--startDate "2024-01-01T00:00:00Z" --endDate "2024-12-31T23:59:59Z" - -Defaults:
posts:listuses 30 days ago to 30 days from now
Media Upload Response
Upload returns JSON with path and metadata:
{
"path": "https://cdn.postiz.com/uploads/abc123.jpg",
"size": 123456,
"type": "image/jpeg"
}
Extract path for use in posts:
RESULT=$(postiz upload image.jpg)
PATH=$(echo "$RESULT" | jq -r '.path')
postiz posts:create -c "Content" -s "2024-12-31T12:00:00Z" -m "$PATH" -i "integration-id"
JSON Mode vs CLI Flags
CLI flags - Quick posts:postiz posts:create -c "Content" -m "img.jpg" -i "twitter-id"
JSON mode - Complex posts with multiple platforms and settings:
postiz posts:create --json post.json
JSON mode supports:
- -Multiple platforms with different content per platform
- -Complex provider-specific settings
- -Scheduled posts
- -Posts with many comments
- -Custom delay between comments

Common Gotchas
1. API Key not set - Always export POSTIZ_API_KEY=key before using CLI
2. Invalid integration ID - Run integrations:list to get current IDs
3. Settings schema mismatch - Check integrations:settings for required fields
4. Media MUST be uploaded to Postiz first - ⚠️ CRITICAL: TikTok, Instagram, YouTube, and many platforms only accept verified URLs. Upload files via postiz upload first, then use the returned URL in -m. External URLs will be rejected!
5. JSON escaping in shell - Use single quotes for JSON: --settings '{...}'
6. Date format - Must be ISO 8601: "2024-12-31T12:00:00Z" and is REQUIRED
7. Tool not found - Check available tools in integrations:settings output
8. Character limits - Each platform has different limits, check maxLength in settings
9. Required settings - Some platforms require specific settings (Reddit needs title, YouTube needs title)
10. Media MIME types - CLI auto-detects from file extension, ensure correct extension
11. Analytics returns {"missing": true} - The post was published but the platform didn't return a post ID. Run posts:missing <post-id> to get available content, then posts:connect <post-id> --release-id "<id>" to link it. Analytics will work after connecting.
