1. A system for providing a pipeline as a service, comprising: a non-transitory memory storing first instructions associated with an incoming pipeline handler; and one or more hardware processors coupled to the memory and operable to read the first instructions from the memory to cause the system to perform operations comprising: providing the incoming pipeline handler as a service to a first application in a first application framework and to a second application in a second application framework, wherein the incoming pipeline handler is provided within a third application framework different from the first application framework and the second application framework; intercepting a first request from a first client device directed at the first application; processing the first request as part of an incoming pipeline in the first application framework for processing incoming requests for the first application, wherein processing the first request comprises: determining that the first request is originated from a first user, and extracting data associated with the first user from the first request; intercepting a second request from a second client device directed at the second application; and processing the second request as part of an incoming pipeline in the second application framework for processing incoming requests for the second application, wherein processing the second request comprises: determining whether the second request is originated from the first user, and in response to a determination that the second request is originated from the first user, appending the data of the first user extracted from the first request to the second request before sending the second request to the second application.
