GraphQL Overview<\/h2>\n
GraphQL is a data query language and runtime that revolutionizes how you build and consume APIs. Originally developed by Facebook in 2012 and open-sourced in 2015, GraphQL has become the preferred choice for modern applications that need efficient, flexible, and performant data fetching.<\/p>\n
Why use GraphQL?<\/h3>\n\n- Get exactly what you need<\/strong>. Unlike traditional REST APIs that return fixed data structures, GraphQL lets you request exactly the fields you need in a single query. This means faster load times, reduced bandwidth usage, and better user experiences.<\/li>\n
- Superior performance<\/strong>. GraphQL minimizes over-fetching and under-fetching of data, allowing you to optimize performance by fetching only the necessary information in a single request. In addition, minimized data transfer is ideal for mobile and low-bandwidth environments.<\/li>\n
- Enhanced developer experience<\/strong>. GraphQL’s strongly typed schema and introspection capabilities provide powerful tools for developers. You can explore the API, get real-time feedback, and leverage auto-completion in modern IDEs, making development faster and more efficient.<\/li>\n<\/ul>\n

REST API Overview<\/h2>\n
The REST API documentation describes the REST APIs that are available in Adobe Commerce (PaaS) and Adobe Commerce as a Cloud Service<\/a> (SaaS).<\/p>\nThe APIs can be used to perform a wide array of tasks. For example:<\/p>\n
\n- Create a shopping app. This can be a traditional app that a user downloads on a mobile device. You could also create an app that an employee uses on a showroom floor to help customers make purchases.<\/li>\n
- Integrate with CRM (Customer Relationship Management) or ERP (Enterprise Resource Planning) backend systems, such as Salesforce or Xero.<\/li>\n
- Integrate with a CMS (Content Management System). Currently, content tagging is not supported.<\/li>\n<\/ul>\n

<\/p>\n
Why use REST API?<\/h3>\n\n- Simplicity and familiarity<\/strong>: REST APIs are easy to understand and widely adopted. We can use several methods like: GET, POST, PUT, DELETE, etc., intuitive for developers and simple to integrate with almost any platform or programming language e.g. web or mobile applications.<\/li>\n
- Scalable and cache-friendly<\/strong>: REST is designed with scalability in mind. Built-in HTTP caching helps reduce server load and improve performance, making REST APIs a solid choice for high-traffic applications and distributed systems.<\/li>\n
- Flexible and reliable integration<\/strong>: REST APIs work seamlessly with web, mobile, and third-party systems. Their stateless nature ensures reliability, easier debugging, and smooth integration with existing tools, services, and legacy systems.<\/li>\n<\/ul>\n
Which one should you use?<\/h2>\n
Choosing between Magento 2 GraphQL<\/strong> and REST API<\/strong> depends on what you\u2019re building, who\u2019s consuming the API, and how much flexibility\/performance you need.
