# Proxy requests an API

> Step-by-step guide on how to proxy requests to an API (using the _proxy_).

<Info>
  Pre-requisite: creation of an integration and at least one connection ([step-by-step guide](/integrate/guides/authorize-an-api)).
</Info>

The [Proxy](/understand/concepts/proxy) lets you query external APIs easily with credentials injection, request logging, and pre-configurations for base URLs, rate-limits, retries, etc.

Here is an example of how to query external APIs with the proxy, using the SDK ([reference](/reference/sdks/node#proxy-get-requests)) and API ([reference](/reference/api/proxy/get)):

    ```typescript
    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);
    }
