Inbound Apps are designed to transform traditional applications into OAuth-compliant identity providers, facilitating seamless interactions between applications, APIs, and AI agents by securely managing user data access and actions. This innovation allows developers to easily enable features such as B2C and B2B connectivity, marketplace authentication, and cross-application data sharing, all while ensuring user consent and data privacy. With Inbound Apps, organizations can define granular scopes for data access, manage consent flows effortlessly, and integrate role-based and scope-based access controls, providing fine-grained authorization that maintains security and organizational governance. This framework supports various use cases, including AI agent connectivity, partner application interactions, and marketplace integrations, thereby preparing applications for the evolving agentic Internet era without necessitating deep OAuth expertise from developers.
