The present disclosure discloses an application-based service providing method, apparatus, and system. The method includes: acquiring an application identifier of a currently running application; and searching a preset application-service relationship table for a service list corresponding to the application identifier, so as to provide a user of the application with a service in the service list, where the application-service relationship table includes a correspondence between an application identifier and a service list, and the service list includes at least one service. The service providing method in the embodiments decouples a third-party service from an application, and even if the application needs version update, the third-party service also does not need to depend on the version update of the application.
