Facebook

Meta's Graph API is technically sophisticated but increasingly restrictive, requiring extensive app review processes.

OAuth2 authentication is well-implemented, with comprehensive documentation covering social media, marketing, and messaging features. The API is powerful for social integrations and advertising, with regular updates and new features. However, access restrictions have tightened significantly, with most useful permissions requiring business verification. Rate limits and policy changes are frequent.

It's essential for social media applications, but expect lengthy approval processes and ongoing compliance requirements.
