OAuth

OAuth (Open Authorization) is an open standard protocol that allows third-party applications to access user data without requiring the user to share their password. Instead of passing credentials directly, OAuth uses access tokens issued by an authorization server. This lets users grant limited, revocable permissions to external services.

OAuth is fundamental to secure integrations between platforms. Without it, connecting two services would require sharing login credentials, creating serious security risks. For digital publishers who rely on multiple tools for analytics, email marketing, and payment processing, OAuth enables those connections safely and gives users control over what data is shared.

FlipLink uses secure authentication methods when connecting to third-party services. For example, integrations with services like Google Sheets and Stripe through the [automation and integrations](/features/automation-and-integrations) feature rely on secure token-based authorization so your data flows between platforms without exposing your passwords. When you sign in to FlipLink or connect an external service, the authentication process keeps your credentials protected while enabling the functionality you need.

A publisher connects their FlipLink account to Google Sheets to automatically export lead capture data. During setup, they authorize FlipLink through a secure consent screen. FlipLink receives a limited access token for their spreadsheet, never their Google password, and lead data syncs automatically from that point forward.
