# Set up Calendly with Nango

> Register an OAuth app with Calendly and connect it to Nango

This guide shows you how to register your own app with Calendly to obtain your OAuth credentials (client id & secret). These are required to let your users grant your app access to their Calendly account.

## Creating a Calendly OAuth App

**1. Create a Calendly developer account**

If you don't already have one, [create a Calendly developer account](https://developer.calendly.com/create-a-developer-account).

**2. Register a new application**

In your Calendly developer dashboard, navigate to the OAuth applications section and create a new application.

**3. Configure your OAuth app**

Fill in the required information for your application:

* **Application Name**: Enter a name for your application
* **Redirect URI**: Enter your Nango callback URL (found in your [Nango integration settings](https://app.nango.dev/dev/integrations))

> [!NOTE]
>
> Only HTTPS redirect URIs will work when your app is in production.

**4. Save your credentials**

After creating the application, you'll receive a **Client ID** and **Client Secret**. Copy these credentials.

**5. Add credentials to Nango**

In Nango, go to your [Calendly integration](https://app.nango.dev/dev/integrations) and enter:

* **Client ID**: Your Calendly OAuth Client ID
* **Client Secret**: Your Calendly OAuth Client Secret
