Option A: Ayrshare + Custom Backend

// Your backend  
const axios = require('axios');  
  
async function scheduleMultiPlatformPost(content, platforms, scheduleTime, mediaUrls) {  
  try {  
    const response = await axios.post('https://app.ayrshare.com/api/post', {  
      post: content,  
      platforms: platforms,  
      mediaUrls: mediaUrls,  
      scheduleDate: scheduleTime  
    }, {  
      headers: {  
        'Authorization': `Bearer ${process.env.AYRSHARE_API_KEY}`,  
        'Content-Type': 'application/json',  
        'Profile-Key': userProfileKey // For multi-user apps  
      }  
    });  
    return response.data;  
  } catch (error) {  
    console.error('Failed to schedule post:', error);  
  }  
}  

Option B: Late API + Webhooks

// Simpler single-user setup  
async function publishAcrossPlatforms(content, platforms, scheduleTime) {  
  const response = await fetch('https://api.late.dev/v1/schedules', {  
    method: 'POST',  
    headers: {  
      'Authorization': `Bearer ${API_KEY}`,  
      'Content-Type': 'application/json'  
    },  
    body: JSON.stringify({  
      post_at: scheduleTime,  
      profile_ids: platforms,  
      text: content  
    })  
  });  
  return response.json();  
}  

Option C: Mixpost (Self Hosted)

  • Deploy on your own infrastructure
  • Access to full codebase for custom integrations
  • Build REST API on top for your automation needs
  • No vendor lock-in

Implementation Roadmap for Your Use Case

  1. Choose Platform based on:
    • Multi-user support needs (Ayrshare/Late if yes)
    • Data privacy requirements (Mixpost if critical)
    • Integration speed (Late for fastest)
    • Budget constraints (Mixpost if cost-sensitive at scale)
  2. Setup Phase:
    • Create developer account
    • Generate API keys
    • Implement OAuth flow for social account linking
    • Test with single platform before scaling
  3. Automation Layer:
    • Build scheduling queue in your database
    • Implement API calls to chosen platform
    • Add error handling & retry logic
    • Set up webhooks for status updates
  4. Content Strategy:
    • Platform-specific customizations (hashtags, link formats)
    • Media optimization per platform
    • Scheduling optimization (best times per platform)

Key Considerations

βœ… Always use OAuth for user account linking (secure and compliant)
βœ… Handle rate limits in your code (implement backoff/queuing)
βœ… Test with sandbox/staging before production deployment
βœ… Monitor API changes by subscribing to changelogs/notifications
βœ… Log all API calls for debugging and audit trails
βœ… Cache platform-specific requirements such as character limits and media specs
