Abstract: This application provides a method performed at a computer server for establishing an association relationship. The computer server queries a first interaction record that corresponds to a public service identifier and a social application identifier of a social platform, and that indicates an interaction performed, by using the public service identifier and the social application identifier, by a first user and a second user; determining whether the first interaction record meets a first preset condition; and establishing an association relationship between the social application identifier and the public service identifier if the first interaction record meets the first preset condition. In this way, an association relationship between a consumer user and a merchant user is automatically established according to offline consumption records of the consumer user.
