Recommended Architecture for Custom Automation
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
- 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)
- Setup Phase:
- Create developer account
- Generate API keys
- Implement OAuth flow for social account linking
- Test with single platform before scaling
- 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
- Content Strategy:
- Platform-specific customizations (hashtags, link formats)
- Media optimization per platform
- Scheduling optimization (best times per platform)
Key Considerations
β
Always use OAuth for user account linking (secure and compliant)
β
Handle rate limits in your code (implement backoff/queuing)
β
Test with sandbox/staging before production deployment
β
Monitor API changes by subscribing to changelogs/notifications
β
Log all API calls for debugging and audit trails
β
Cache platform-specific requirements such as character limits and media specs
