# Transaction Deduplication Function Marketing tools are now capable of capturing more data than ever before, which means that they need to have good routines in place to separate the good data from the bad. As a tag management expert, it is your job to provide the necessary parameters to make good decisions. Often, this will involve sending a conversion signal to a network only once it has occurred, which is a very common practice in tag management. With JENTIS, you have a more resilient tool for handling this job. In this guide, we will show you how to implement an efficient way to handle deduplication with JENTIS on the server side. This will help you save resources on the frontend and ensure a stable process that runs smoothly on the server side. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
