# Taggings Overview

> Tags and taggings are two resources in the Platform API that, when used together, give end users more control over organizing their transactions.

A tag is a custom label that can be applied to a transaction.

After you create a tag, use it for tagging. This means you should actually apply the tag to a particular transaction.

Together, they're a powerful tool for personalization, customization, and money management.

For a guide on creating a tag and then applying it to a specific transaction with a tagging, see [Custom Tags and Taggings](/products/experience/pfm/integration-guides/personalization/).
