# HighLevel

There are two types of API keys in HighLevel: agency API keys and location API keys. For Middle's HighLevel app, you'll want to use your location API key.

You can get your [location API key](https://help.gohighlevel.com/support/solutions/articles/48001060529-highlevel-api#1.%C2%A0Location-Level-%3E-Settings%C2%A0%3E-Business-Info) from the sub-account you are connecting. This will be used for all the APIs to manage all the objects that are part of subaccounts (contacts, appointments, opportunities, etc.).

1. Go to **Settings**
2. Go to **Business Info**
3. Go to API Key

Enter the API key in [your HighLevel app connection](/middle-docs/building-workflows/connect-or-edit-an-app-connection.md).
