# Connector Directory

Probo connects to these providers as access sources. Each guide covers the credential to create, the data Probo collects, and how to connect it.

The connection buttons shown in **Access Reviews** > **Sources** > **Add Source** are the source of truth for the methods available in your deployment. Some providers use OAuth or client credentials even when the guides below focus on API-key connectors.
