OAuth integration is the implementation of OAuth-based flows that allow users or systems to grant limited access without sharing passwords. OAuth is commonly used for connecting applications, enabling single sign-on, and authorizing third-party services to act on a user’s behalf in a controlled way.
How OAuth Fits Into Identity and Access
OAuth scope design is where many integrations fail. If scopes are too broad, security teams will reject the integration. If scopes are too narrow, users cannot complete tasks. Start with the smallest viable scope set and expand based on real usage.
OAuth supports both authentication and authorization by providing tokens that represent a user or client and the scopes they granted. This is especially useful for embedded editors and APIs, where the integration needs to access resources securely without relying on long-lived credentials.
OAuth in API and Integration Work
OAuth is often used to secure a public API and to control which operations an external system can perform. If you have event-driven workflows, keep token-based access separate from webhook verification. For webhook verification, rely on signing secrets and signature checks rather than OAuth tokens. This prevents accidentally granting webhook endpoints more privilege than they need and keeps your security model simpler.
Implementation Considerations
OAuth integration requires careful token storage, rotation, and scope design. Keep scopes narrow, expire tokens appropriately, and provide clear consent screens so users understand what they are granting. If you support both user tokens and service tokens, document which flows apply to which use cases. For example, a user token may be required for interactive template editing, while a service token may be used for automated provisioning. In SaaS products, also include tenant context so tokens cannot be reused across organizations.
