The Apollo Connectors for REST APIs bring declarative, graph-based orchestration technology to teams using non-GraphQL APIs. This allows developers to describe the data model they want and let the Apollo infrastructure figure out how to make it happen, replacing procedural code with a more efficient and scalable approach. The connectors include features such as API call chaining, parallelization, error handling, authentication, and transformation of responses, all made available through GraphQL schemas and operations. With Apollo Connectors, developers can now use graph-based API orchestration without needing to add GraphQL APIs or create new services, making it easier to build applications and integrate multiple APIs together. The technology is designed to replace procedural code with a more efficient and scalable approach, enabling faster development and reduced maintenance costs.
