REST API Concepts and Their Use in MQL5 Integrations

Summary

The article introduces APIs and REST as ways for separate applications to exchange data, then outlines common API styles and REST conventions. It describes HTTP methods such as GET, POST, PUT, and DELETE, resource-based requests, and typical JSON or XML responses. It also contrasts REST with SOAP and mentions GraphQL and RPC approaches, alongside general topics such as authentication and transport security.

For trading software, the article frames REST APIs as a route for connecting MQL5 programs to external services and financial data, mentioning a Coinbase integration as an intended practical example. However, the provided text is largely introductory: the practical MQL5 implementation is not included in full, and it offers no trading strategy, performance evidence, or security analysis beyond broad guidance. Readers would need implementation details and current API documentation before applying the concepts to a live system.

Key ideas

• APIs let software exchange data and use one another's services through defined interfaces.
• REST commonly uses HTTP methods to operate on resources and returns structured data.
• API keys, tokens, and encrypted transport are examples of access and security controls.
• The article connects these concepts to MQL5 but provides limited practical implementation detail in the supplied text.
