Pipelines in Sitecore

During the interview, many developers face questions about giving name of a particular pipeline for a particular purpose. And in most of the cases, we don’t remember name because we have never given attention to it during development. While writing code, we find the pipeline, add the processor and go head, but we don’t memorize that pipeline name.

So, to make it easy to memorize the name and purpose of pipelines, I’m trying to list them here to make sure never fail to answer the interview question.

Pipeline namePurpose
initializeRuns when ASP.NET initializes Sitecore. In some cases, you can use a hook rather than add a processor to the initialize pipeline.
