Associations, colleges, and even telecommunications providers often have member-facing portals which collect information from a wide variety of systems and allow those members to make changes to that information (e.g. by adding a new subscription). Ideally, all of the details of that change are immediately available to the member throughout the portal and any 3rd party they may be redirected to. For example, if their new subscription gives them access to a research platform, they expect to see a new link to that platform show up, and give them the access they paid for.
