# Proxy requests

> How to use the requests proxy from Nango

Use the requests proxy to make authenticated API requests to the external API.

## How to use the proxy

Make sure you have an [integration configured](/guides/auth/auth-guide#guide) in your environment, and at least one [connection](/guides/auth/auth-guide#overview) available for it.

You can use the proxy with the [Node SDK](/reference/backend/backend-sdk/node#proxy) or [REST API](/reference/backend/http-api/proxy/get):

    ```typescript theme={null}
    try {
        const res = await nango.proxy({
            method: 'POST',
            baseUrlOverride: 'https://api.example.com',
            endpoint: '/external-endpoint',
            providerConfigKey: '<string>',
            connectionId: '<string>',
            retries: 5, // Retries with exponential backoff (optional, default 0)
            data: {
                id: 1,
                colorId: 'blue',
                selected: true
            }
        });

        // Response was 200!
        // See https://axios-http.com/docs/res_schema
        console.log(res.data);
    } catch (error) {
        // Status of response != 200
        // See https://axios-http.com/docs/handling_errors
        console.log(error.response.data);
        console.log(error.response.status);
        console.log(error.response.headers);
    }
    ```
