# 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

<Steps>
  <Step title="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).
  </Step>

  <Step title="Register a new application">
    In your Calendly developer dashboard, navigate to the OAuth applications section and create a new application.
  </Step>

  <Step title="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.</Note>
  </Step>

  <Step title="Save your credentials">
    After creating the application, you'll receive a **Client ID** and **Client Secret**. Copy these credentials.
  </Step>

  <Step title="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
  </Step>
</Steps>
