  <Tab title="🚀 Quickstart">
    <Steps>
      <Step title="Create an integration">
        In Nango ([free signup](https://app.nango.dev)), go to [Integrations](https://app.nango.dev/dev/integrations) -> *Configure New Integration* -> *Fillout*. Nango doesn't provide a test OAuth app for Fillout yet. You’ll need to set up your own by following these [instructions](#🧑%E2%80%8D💻-oauth-app-setup). After that, make sure to add the OAuth client ID and secret in the integration settings in Nango.
      </Step>

      <Step title="Authorize Fillout">
        Go to [Connections](https://app.nango.dev/dev/connections) -> *Add Test Connection* -> *Authorize*, then log in to Fillout. Later, you'll let your users do the same directly from your app.
      </Step>

      <Step title="Call the Fillout API">
        Let's make your first request to the Fillout API (fetch a list of all your forms). Replace the placeholders below with your [secret key](https://app.nango.dev/dev/environment-settings), [integration ID](https://app.nango.dev/dev/integrations), and [connection ID](https://app.nango.dev/dev/connections):

        <Tabs>
          <Tab title="cURL">
            ```bash theme={null}
            curl "https://api.nango.dev/proxy/v1/api/forms" \
             -H "Authorization: Bearer <NANGO-SECRET-KEY>" \
             -H "Provider-Config-Key: <INTEGRATION-ID>" \
             -H "Connection-Id: <CONNECTION-ID>" \
            ```
          </Tab>

          <Tab title="Node">
            Install Nango's backend SDK with `npm i @nangohq/node`. Then run:

            ```typescript theme={null}
            import { Nango } from '@nangohq/node';

            const nango = new Nango({ secretKey: '<NANGO-SECRET-KEY>' });

            const res = await nango.get({
              endpoint: '/v1/api/forms',
              providerConfigKey: '<INTEGRATION-ID>',
              connectionId: '<CONNECTION-ID>'
            });

            console.log(res.data);
            ```
          </Tab>
        </Tabs>

        Or fetch credentials dynamically via the [Node SDK](/reference/sdks/node#get-a-connection-with-credentials) or [API](/reference/api/connection/get).
      </Step>
    </Steps>

    ✅ You're connected! Check the [Logs](https://app.nango.dev/dev/logs) tab in Nango to inspect requests.

        5. Submit the form to create your application.
      </Step>

      <Step title="Obtain your OAuth credentials">
        1. After creating the app, you'll see your **Client ID** displayed.
        2. Click **Generate Secret** to create your **Client Secret**.
        3. Copy both the **Client ID** and **Client Secret**, you'll need these when configuring your integration in Nango.
