This is the official Python library made for Shopify users to access the admin functionality of their accounts for use in building 3rd party applications. It was developed and is currently supported by Shopify. It provides a similar interface as does the Shopify Ruby Gem. All API usage happens through Shopify applications; shop owners can create applications for themselves through their own admin. Developers are given functionality across articles, assets, customers, events and more. The API uses a RESTful interface and responses are formatted in XML and JSON.
The third largest retailer in the world, Tesco, a grocery-and-more chain largely in the UK, will soon unveil a REST API for its online store (Tesco API profile). Developers will be able to search products, as well as get nutritional information, such as how many calories are in a serving of crisps or biscuits.
ShippingEasy consists of a cloud-based platform that allows online merchants to manage the processing and tracking of orders from a single interface. Merchants can integrate shipping information from multiple sites (e.g. eBay, personal site, physical warehouse, etc.) with the same interface and shop rates across various carrier lines. In addition to over ten existing integrations with e-commerce sites (e.g. Magento, eBay, Shopify, etc.), ShippingEasy offers a custom API that allows developers to incorporate the ShippingEasy platform into third party apps and sites.
