# Environments

## API base URLs

These base URLs are used for initiating platform-level requests, such as [Order Acknowledgement](/integration/ecommerce/order-acknowledgement.md), [WebToPrint](/integration/api/webtoprint-w2p.md), the [Image QueryString API](/integration/api/image-querystring-api.md), and more.

* Staging: <https://staging.spectrumcustomizer.com>
* Production: <https://api.spectrumcustomizer.com>

{: .note }

> The staging hostname intentionally omits the `api.` prefix used in production. Always reference the values above rather than constructing one by analogy.

## CDN base URLs

These URLs are used for retrieving static content from Spectrum, including the [Javascript bundle file](/integration/ecommerce/front-end-integration.md).

* Staging: <https://cdn-staging.spectrumcustomizer.com>
