  <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* -> *Sellsy*. Nango doesn't provide a test OAuth app for Sellsy 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, Secret shopper, and scopes in the integration settings in Nango.
      </Step>

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

      <Step title="Call the Sellsy API">
        Let's make your first request to the Sellsy API (fetch a list of contacts). 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/v2/contacts" \
              -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: '/v2/contacts',
                params: {
                  maxResults: 10
                },
                providerConfigKey: '<INTEGRATION-ID>',
                connectionId: '<CONNECTION-ID>'
            });

            console.log(JSON.stringify(res.data, null, 2));
            ```
          </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.

    <Tip>
      Next step: [Embed the auth flow](/guides/primitives/auth) in your app to let your users connect their Sellsy accounts.
    </Tip>
  </Tab>

  <Tab title="🧑‍💻 OAuth app setup">
    <Steps>
      <Step title="Create Sellsy account">
        If you don't already have one, sign up for a [Sellsy account](https://www.sellsy.com/onboarding/quicktrial?lang=en).
      </Step>

      <Step title="Create an API access">
        1. Navigate to your [Developer page](https://www.sellsy.com/developer/api-v2).
        2. Click **Create API access** and select between:

        * **Private** - API access limited to staffs of your Sellsy account.
        * **Public** - API access to connect to all Sellsy accounts. A validation by Sellsy is also required.

        3. Fill in all the required information. For **Redirect URL**, add `https://api.nango.dev/oauth/callback` and select the permissions you want to give to your API access.
        4. Click **Save**.
      </Step>

      <Step title="Obtain your client credentials">
        1. After creating the app, copy the **Client ID** and **Secret shopper** that Sellsy will generate. You'll need these when configuring your integration in Nango.
      </Step>

      <Step title="Next">
        Follow the [*Quickstart*](/getting-started/quickstart).
      </Step>
    </Steps>

    <Note> For security reasons, **Public** access must be validated by Sellsy teams to justify its use. To do this, please send us an email to [contact@sellsy.com](mailto:contact@sellsy.com) </Note>
