# API documentations

You can authenticate APIs using either [OAuth2](/~/changes/8nxu1gB5bGpm7B5IZlQ8/developer/authorizing-rememberizer-apps.md) or [API keys](/~/changes/8nxu1gB5bGpm7B5IZlQ8/developer/registering-and-using-api-keys.md). OAuth2 is a standard authorization framework that enables applications to securely access specific documents within a system. On the other hand, API keys provide a simpler method to retrieve documents from a common knowledge base without the need to undergo the OAuth2 authentication process.
