# App Reference

## Getting app credentials

To connect with any app, you will need your own API credentials to facilitate the integration. Depending on the app, the nature of this integration varies. Oftentimes, an API partnership is required with the app provider, an OAuth application must be created in the software platform, or it's as simple as grabbing an API key from the app admin.

API credentials are either entered on the [app connection page](/middle-docs/building-workflows/connect-or-edit-an-app-connection.md) or at an organization level, in the [API keys](/middle-docs/app-development/credential-storage.md) tool.

All OAuth authentications require OAuth application credentials to be entered in the [API keys](/middle-docs/app-development/credential-storage.md) menu
{% endhint %}

### Redirect URLs

When an app authentication requires a redirect URL, as is the case for OAuth flows, you'll need to use a redirect URL that returned to your Middle instance. You'll want to use the following: `https://`<mark style="color:orange;">`{`</mark>*<mark style="color:orange;">`ENTER YOUR INSTANCE NAME HERE`</mark>*<mark style="color:orange;">`}`</mark>`.middle.app/oauth-redirect-uri/`
