A computer-implemented method of a server, the method comprising: defining a user lifecycle application programming interface, hereinafter referred to as API, comprising a plurality of user lifecycle functions for use by third-party applications, the third-party applications authored by different organizations; storing a plurality of lifecycle code modules corresponding to a plurality of third-party applications, each of the lifecycle code modules implementing the user lifecycle functions of the user lifecycle API for one of the plurality of third-party applications, wherein code of a first one of the lifecycle code modules differs from code of a second, different one of the lifecycle code modules; identifying an occurrence of a user lifecycle event which affects the use of the third party applications by a first user of an organization and which is triggered by a user password rotation policy evaluated by the server; and responsive to identifying the occurrence of the user lifecycle event: identifying the first user associated with the user lifecycle event; mapping the user lifecycle event to one of the user lifecycle functions of the user lifecycle API associated with the user lifecycle event; identifying, as a subset of the third-party applications, third-party applications to which the organization has granted the first user access; and for each third-party application of a plurality of the third-party applications of the identified subset: identifying the lifecycle code module of the plurality of lifecycle code modules corresponding to the third-party application, and calling the identified lifecycle code module to implement the user lifecycle function associated with the user lifecycle event, thereby making a change to data of an account of the first user in the third-party application, the third-party application being remote from the server. defining a user lifecycle application programming interface, hereinafter referred to as API, comprising a plurality of user lifecycle functions for use by third-party applications, the third-party applications authored by different organizations; storing a plurality of lifecycle code modules corresponding to a plurality of third-party applications, each of the lifecycle code modules implementing the user lifecycle functions of the user lifecycle API for one of the plurality of third-party applications, wherein code of a first one of the lifecycle code modules differs from code of a second, different one of the lifecycle code modules; identifying an occurrence of a user lifecycle event which affects the use of the third party applications by a first user of an organization and which is triggered by a user password rotation policy evaluated by the server; and responsive to identifying the occurrence of the user lifecycle event: identifying the first user associated with the user lifecycle event; mapping the user lifecycle event to one of the user lifecycle functions of the user lifecycle API associated with the user lifecycle event; identifying, as a subset of the third-party applications, third-party applications to which the organization has granted the first user access; and for each third-party application of a plurality of the third-party applications of the identified subset: identifying the lifecycle code module of the plurality of lifecycle code modules corresponding to the third-party application, and calling the identified lifecycle code module to implement the user lifecycle function associated with the user lifecycle event, thereby making a change to data of an account of the first user in the third-party application, the third-party application being remote from the server. identifying the first user associated with the user lifecycle event; mapping the user lifecycle event to one of the user lifecycle functions of the user lifecycle API associated with the user lifecycle event; identifying, as a subset of the third-party applications, third-party applications to which the organization has granted the first user access; and for each third-party application of a plurality of the third-party applications of the identified subset: identifying the lifecycle code module of the plurality of lifecycle code modules corresponding to the third-party application, and calling the identified lifecycle code module to implement the user lifecycle function associated with the user lifecycle event, thereby making a change to data of an account of the first user in the third-party application, the third-party application being remote from the server. identifying the lifecycle code module of the plurality of lifecycle code modules corresponding to the third-party application, and calling the identified lifecycle code module to implement the user lifecycle function associated with the user lifecycle event, thereby making a change to data of an account of the first user in the third-party application, the third-party application being remote from the server.
