Twitter Thread Scheduling API

Overview

The Twitter Thread Scheduling API allows you to programmatically create and schedule multi-tweet Twitter threads. This powerful endpoint supports both text-only threads and threads with image attachments, giving you complete control over your Twitter storytelling and content strategy.

What You Can Do

Create multi-tweet Twitter threads with sequential content
Schedule threads for future publication at optimal times
Include images in individual thread tweets for enhanced engagement
Create draft threads for review and approval workflows
Manage complex Twitter narratives programmatically
Automate your Twitter thread publishing strategy

Common Use Cases

Storytelling: Break down complex narratives into digestible thread sequences
Educational Content: Create step-by-step tutorials and how-to guides
Marketing Campaigns: Launch product announcements across multiple connected tweets
Thought Leadership: Share detailed insights and industry analysis
News Organizations: Break down complex stories into thread format
Content Creators: Publish episodic content and series
Technical Documentation: Share code examples and technical explanations
Event Coverage: Live-tweet events with connected narrative threads

Authentication

All API requests require authentication using an API key passed in the request header.

X-API-KEY: your_api_key_here

Security Note: Keep your API key secure and never expose it in client-side code or public repositories.

Rate Limiting

Daily Limit: 30 requests per day per API key

Resets at midnight UTC
Plan your thread publishing schedule accordingly
Consider using draft status for content that needs review
Monitor your usage to avoid hitting the daily limit
Each thread creation counts as one request regardless of thread length

Thread Structure and Limitations

Twitter Thread Requirements

Maximum Thread Length: Up to 25 tweets per thread
Character Limit: Each tweet in the thread follows Twitter’s 280-character limit
Image Limit: Up to 4 images per individual tweet within the thread
Supported Formats: JPEG, PNG, GIF, WebP for images
File Size: Maximum 5MB per image file
Thread Continuity: Tweets are automatically connected in sequence

Thread Content Strategy

Opening Tweet: Make it compelling to encourage users to read the full thread
Sequential Flow: Ensure each tweet flows logically to the next
Closing Tweet: End with a strong conclusion or call-to-action
Engagement Hooks: Use questions, cliffhangers, or teasers between tweets
Visual Consistency: Maintain consistent image style throughout the thread

API Variants

The Twitter Thread API supports two main variants:

1. Thread with Images

Create threads where individual tweets can include image attachments.

File: thread_with_image.mdx
Use Case: Visual storytelling, tutorials with screenshots, product showcases
Image Support: Up to 4 images per tweet, multiple supported formats

2. Thread without Images

Create text-only threads for pure content storytelling.

File: thread_without_image.mdx
Use Case: Written narratives, text-based tutorials, opinion pieces
Focus: Pure text content with optimal character utilization

Thread Content Structure

Threads use a structured JSON format in the post_content parameter:

{
  "0": {
    "text": "First tweet in the thread...",
    "images": [] // or ["image_url1", "image_url2"]
  },
  "1": {
    "text": "Second tweet continues the story...",
    "images": []
  },
  "2": {
    "text": "Final tweet with conclusion...",
    "images": []
  }
}

Structure Rules

Sequential Numbering: Start from “0” and increment sequentially
Text Field: Required for each thread segment, up to 280 characters
Images Array: Empty array for text-only tweets, populated for image tweets
Consistency: All thread segments must follow the same structure

Best Practices

Content Planning for Threads

Thread Outline: Plan your entire thread before writing individual tweets
Hook Strategy: Start with a compelling opening that promises value
Logical Flow: Ensure each tweet builds upon the previous one
Pacing: Balance information density across tweets
Visual Breaks: Use images strategically to break up text-heavy content
Conclusion: End with a memorable takeaway or call-to-action

Optimal Thread Timing

Peak Hours: Schedule during high-engagement periods (8-10 AM, 7-9 PM)
Audience Consideration: Time threads when your specific audience is most active
Content Type: Educational threads perform well during business hours
Weekend Strategy: Storytelling threads often perform well on weekends
Time Zone Awareness: Consider your global audience’s active hours

Thread Engagement Optimization

Opening Impact: First tweet determines thread success - make it count
Thread Indicators: Use 🧵 emoji or “Thread:” to signal multi-tweet content
Numbering: Consider adding “1/n” format to help readers track progress
Engagement Prompts: Ask questions throughout to encourage interaction
Retweet Strategy: End with a request to retweet the first tweet
Cross-Promotion: Mention the thread in other content to drive traffic

Technical Implementation

Content Validation: Validate each tweet’s character count before submission
Image Optimization: Compress images for faster loading while maintaining quality
Error Handling: Implement robust error handling for thread creation
Draft Workflow: Use draft status for collaborative thread creation
Scheduling Strategy: Plan thread timing for maximum impact

Thread Performance Analytics

Key Metrics to Track

Thread Completion Rate: Percentage of users who read the entire thread
Individual Tweet Performance: Engagement metrics for each thread segment
Click-Through Rates: If including links, track clicks per thread position
Retweet Distribution: Which tweets in the thread get reshared most
Reply Patterns: Where in the thread users engage most frequently

Optimization Insights

Optimal Length: Monitor how thread length impacts completion rates
Content Positioning: Identify which positions get highest engagement
Image Impact: Compare performance of threads with and without images
Topic Analysis: Track which thread topics resonate most with your audience
Timing Analysis: Optimize posting times based on thread performance data

Content Guidelines

Writing Effective Threads

Clarity First: Each tweet should be understandable on its own
Transitional Flow: Create smooth transitions between tweets
Value Density: Pack valuable information into each segment
Readability: Use short sentences and clear language
White Space: Don’t fill every character - readability matters
Call-to-Actions: Strategically place CTAs throughout the thread

Visual Content Strategy

Consistent Style: Maintain visual consistency across thread images
Complementary Visuals: Images should enhance, not duplicate, text content
Quality Standards: Use high-resolution images that look professional
Alternative Text: Always consider accessibility with image descriptions
Brand Consistency: Ensure images align with your brand guidelines

Error Handling and Troubleshooting

Common Thread Creation Issues

Character Limit Exceeded: Individual tweets exceeding 280 characters
Invalid JSON Structure: Malformed post_content parameter
Image Upload Failures: File size or format issues
Scheduling Conflicts: Past dates or invalid timestamp formats
Missing Parameters: Required fields not included in request

Thread-Specific Validations

Sequential Numbering: Ensure thread segments are numbered correctly
Content Completeness: All thread segments must have text content
Image Limits: Respect per-tweet image limitations
Thread Length: Stay within maximum thread length limits
Consistency: Maintain consistent structure across all segments
