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>"

Essential Commands

Setup

# Required environment variable
export POSTIZ_API_KEY=your_api_key_here

# Optional custom API URL
export POSTIZ_API_URL=https://custom-api-url.com

Integration Discovery

# List all connected integrations
postiz integrations:list

# Get settings schema for specific integration
postiz integrations:settings <integration-id>

# Trigger integration tool to fetch dynamic data
postiz integrations:trigger <integration-id> <method-name>
postiz integrations:trigger <integration-id> <method-name> -d '{"param":"value"}'

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 Handling

If 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 5000 \  # Delay between comments in ms
  -i "integration-id"

Internally creates:

{
  "posts": [{
    "value": [
      { "content": "Main post", "image": ["image1.jpg", "image2.jpg"] },
      { "content": "Comment 1", "image": ["comment-img.jpg"], "delay": 5000 },
      { "content": "Comment 2", "image": ["another.jpg", "more.jpg"], "delay": 5000 }
    ]
  }]
}

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:list uses 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.
