# Flow Commerce (Global-e) > Flow Commerce is a cross-border ecommerce platform (now part of Global-e) that lets merchants localize the entire international shopping experience — 100+ currencies, localized checkout and payment methods, guaranteed landed-cost (duties and taxes) calculation, international shipping and returns, and localized product feeds. Flow exposes these capabilities as a REST API defined in APIBuilder, with generated Ruby and Node.js client SDKs. ## APIs - [Flow REST API (APIBuilder service)](https://app.apibuilder.io/flow/api): The Flow Commerce REST API definition — orders, catalog/items, localization, experiences, payments, and logistics resources. ## Docs - [Flow developer documentation](https://docs.flow.io/): Developer portal and API reference (password-gated). - [Flow console / login](https://console.flow.io/login): Merchant and developer console sign-in. - [Flow blog](https://www.flow.io/blog): Product and cross-border commerce articles. ## SDKs - [Ruby SDK (flowcommerce)](https://rubygems.org/gems/flowcommerce): `gem install flowcommerce` — native Ruby client, source at github.com/flowcommerce/ruby-sdk. - [Node.js SDK (@flowio/node-sdk)](https://www.npmjs.com/package/@flowio/node-sdk): `npm install @flowio/node-sdk` — source at github.com/flowcommerce/node-sdk. ## Source - [flowcommerce on GitHub](https://github.com/flowcommerce): First-party open-source repositories, including the SDKs, apibuilder tooling, and reference data (json-reference). ## Company - [flow.io](https://www.flow.io/): Company site (redirects to Global-e). - [Privacy Policy](https://www.flow.io/privacy-policy) - [Contact / support](https://www.flow.io/contact-us)
