REST API vs. GraphQL

Two common API architectures for handling client-server communication in SaaS applications.

What is the difference between REST API and GraphQL?

REST API and GraphQL are two different methods for building and querying APIs, each with its own strengths and use cases.

REST APIs use predefined endpoints, while GraphQL allows clients to request exactly the data they need.

Key differences include:

  • REST relies on multiple endpoints, GraphQL uses a single endpoint
  • GraphQL reduces over-fetching of data, REST requires multiple requests
  • REST follows HTTP methods (GET, POST, etc.), GraphQL uses a query language

    • Choosing between REST and GraphQL depends on performance, flexibility, and developer needs.
