# Frequently Asked Questions

> Answers to common questions about the ZenRows Go SDK.

### Setup and compatibility

<AccordionGroup>
  <Accordion title="What Go versions does the SDK support?" icon="golang">
    Go 1.23.1 or later, matching the version pinned in the SDK's `go.mod`.
  </Accordion>

  <Accordion title="What's the correct import path?" icon="download">
    `github.com/zenrows/zenrows-go-sdk/service/api`, singular `service`. The package name you import it as is `scraperapi`.
  </Accordion>

  <Accordion title="Does the SDK support PATCH or DELETE requests?" icon="ban">
    No. The Universal Scraper API only accepts `GET`, `POST`, and `PUT`. Calling `Scrape` with any other method returns an `InvalidHTTPMethodError` immediately.
  </Accordion>

  <Accordion title="Does the SDK support Proxy Mode?" icon="route">
    No. The SDK talks to the Universal Scraper API's endpoint directly (API Mode). If you want to use ZenRows as a proxy in your own HTTP client instead, see the [Proxy Mode documentation](/universal-scraper-api/universal-scraper-api-setup#connection-modes) rather than the SDK.
  </Accordion>
</AccordionGroup>

### Requests, errors, and concurrency

<AccordionGroup>
  <Accordion title="How do I set a request timeout?" icon="clock">
    Pass a `context.Context` created with `context.WithTimeout` to `Get`, `Post`, or `Put`. We recommend not setting a timeout below 3 minutes, since canceling a request client-side doesn't immediately free up the concurrency slot on ZenRows' side.
  </Accordion>

  <Accordion title="Why doesn't a failed request return a Go error?" icon="shield-halved">
    By design, a non-2xx HTTP response is still a successful round trip as far as the SDK is concerned, it returns a `*Response` with `err == nil`. Check `response.IsSuccess()`, `response.IsError()`, or `response.StatusCode()` yourself. See [Error Handling and Retries](/universal-scraper-api/sdk/go/error-handling-and-retries).
  </Accordion>

  <Accordion title="What's the default concurrency limit?" icon="gauge-high">
    The default is 5. The SDK creates an internal semaphore capped at 5 even without an explicit `WithMaxConcurrentRequests` call. Set it higher if your plan allows more concurrent requests, or lower it if you're seeing `429 Too Many Requests` errors.
  </Accordion>

  <Accordion title="Which status codes are retried automatically?" icon="rotate">
    `422`, `429`, and `500`, plus network-level failures. `502`, `503`, and `504` are not retried by default.
  </Accordion>
</AccordionGroup>
