## Overview {#overview}

Your initial [portfolio](https://developer.mastercard.com/riskrecon-api/documentation/glossary/index.md#portfolio) is built during your onboarding process by your Customer Support team. When building the portfolio, RiskRecon assigns a unique ID to each [TOE](https://developer.mastercard.com/riskrecon-api/documentation/glossary/index.md#toe) called the `toe_id`. The `toe_id` is required for most RiskRecon API endpoint calls.

You can either add one TOE at a time or in bulk to your portfolio. You can add both [existing and new TOEs](https://developer.mastercard.com/riskrecon-api/documentation/glossary/index.md#toe) to your portfolio.

The RiskRecon portfolio provides several advantages, such as an automated vendor onboarding process which eliminates manual assessments of a vendor. This makes way for efficient and seamless vendor assessment, selection, and onboarding.
