What is Buffer API?
Buffer API provides programmatic access to Buffer's social media publishing and management capabilities. It allows developers to build social media features directly into their own applications, handling publishing to Twitter, Facebook, Instagram, LinkedIn, TikTok, Pinterest, and other platforms. The API includes scheduling, analytics, team collaboration, and account management features, covering the core workflows that social media teams need day-to-day.
It's designed for developers building social tools, agencies managing multiple client accounts, and SaaS platforms wanting to add social publishing functionality without building from scratch. Rather than implementing integrations with each social network separately, developers use Buffer's API to abstract away platform-specific differences and let users publish to all their accounts at once.
The API is accessible through Buffer's existing pricing plans, with a free tier for testing and paid plans for production use.
