18. API Specification

This chapter describes the APIs used in the GNU Taler project. It includes both APIs that are pre-existing as well as APIs specific to the project.

These protocol specifications define the interfaces between the core components of GNU Taler. Most of these interfaces use HTTP-based RESTful protocols using JSON. In the documentation, we use TypeScript syntax to describe the JSON objects used in our REST APIs.
