# What is the Quotivity API?

> The Quotivity API let's you manage Price Books and Bundles using the same APIs that we use internally. Anything you see and do with Price Books or Bundles in Quotivity, you can accomplish with these APIs!

Combined with the [HubSpot APIs](https://developers.hubspot.com/docs/api-reference/overview), you can accomplish any integration use case you may have.

# Understanding Quotivity

Before you get too far with integrating with Quotivity, it's important to understand the core product.

## A Foundation in HubSpot

Quotivity is built for HubSpot, exclusively. We use HubSpot Products, Quotes, and Line Items. In most cases, we query this information from HubSpot in realtime.
