Platform Adapters

Platform adapters handle the conversion and publishing of content to each social media platform.

Architecture Diagram​

Common Interface​

All platform adapters implement a common interface:

MethodDescription
authenticate()Handle OAuth or API key authentication
publish()Publish content to the platform
validate()Validate content against platform rules
getMetrics()Retrieve engagement metrics

Platform Constraints​

Twitter/X​

  • Character limit: 280 characters
  • Hashtags: Maximum 30
  • Images: Up to 5MB
  • Videos: Up to 512MB

LinkedIn​

  • Character limit: 3,000 characters
  • Hashtags: Maximum 30
  • Images: Up to 8MB
  • Videos: Up to 200MB

Instagram​

  • Character limit: 2,200 characters
  • Hashtags: Maximum 30
  • Images: Up to 8MB
  • Videos: Up to 4GB
  • Aspect ratios: 1:1, 4:5, or 1.91:1

Rate Limiting​

The adapter layer includes built-in rate limiting:

  • Rate Limiter: Enforces API rate limits per platform
  • Exponential Backoff: Automatic retry with increasing delays
  • Circuit Breaker: Prevents cascading failures when a platform is down

Extensibility​

New platform adapters can be added by implementing the common interface. The architecture supports future platforms like TikTok, Facebook, and others.
