Reddit-Specific Features

🎯

Subreddit Targeting

Post to one or multiple subreddits simultaneously. Target the exact communities where your content belongs.

📝

Post Types

Create self posts, link posts, image posts, or video posts. Each type is optimized for Reddit's native rendering.

🏷

Flair Support

Automatically discover and apply required flairs for each subreddit. Never have a post rejected for missing flair again.

🔄

Cross-Posting

Share content across multiple subreddits in a single command. Each subreddit gets its own title and flair configuration.

🔗

Link & Media Posts

Share URLs, images, or videos directly. Link posts drive traffic while media posts maximize engagement within Reddit.

📅

Scheduled Posting

Schedule Reddit posts for peak activity times. Hit the front page by posting when your target subreddits are most active.

How It Works

Find Your Reddit Integration

List your connected accounts and grab your Reddit integration ID. You can also discover available flairs for any subreddit before posting.

Discovery

# List all integrations
postiz integrations:list

# Filter for Reddit
postiz integrations:list | jq \
  '.[] | select(.identifier=="reddit")'

# Get Reddit settings schema
postiz integrations:settings <reddit-id>

# Discover flairs for a subreddit
postiz integrations:trigger <reddit-id> \
  getFlairs -d '{"subreddit":"programming"}'

Choose Your Post Type

Reddit supports multiple post types. Self posts contain text, link posts share URLs, and image/video posts upload media directly. Pick the right type for your content.

Post Types

# Self post (text only)
"type": "self"

# Link post (shares a URL)
"type": "link"
"url": "https://example.com/article"

# Image post
"type": "image"
# Use -m flag with image URL

# Video post
"type": "video"
# Use -m flag with video URL

Create Your Post

Schedule a Reddit post with your content, target subreddit, post type, and flair. You can post to multiple subreddits at once by adding more items to the subreddit array.

Post Creation

postiz posts:create \
  -c "Check this out" \
  -s "2025-03-01T09:00:00Z" \
