Project

Kiota is a command line tool for generating an API client to call any OpenAPI described API you are interested in. The goal is to eliminate the need to take a dependency on a different API SDK for every API that you need to call. Kiota API clients provide a strongly typed experience with all the features you expect from a high quality API SDK, but without having to learn a new library for every HTTP API.

This library builds on top of the Microsoft.OpenAPI.NET library to ensure comprehensive support for APIs that use OpenAPI descriptions. One of the goals of the project is to provide the best code generator support possible for OpenAPI and JSON Schema features. The conceptual documentation describes how kiota works and the high level concepts, this readme documents how to get started with Kiota.

Getting started

Generating SDKs

1. Install required tools and dependencies. (refer to the Supported Languages table under the Required tools & dependencies column)
2. Get Kiota using one of the available options.
3. Generate your API client, checkout the Parameters reference for the different options.
4. Start calling your API using your fluent API Client.

Supported languages

The following table provides an overview of the languages supported by Kiota and the progress in the implementation of the different components.

Parameters reference

Parameters are documented here.

Debugging

Make sure you install the pre-requisites first. If you are using Visual Studio Code as your IDE, the launch.json file already contains the configuration to run Kiota. By default this configuration will use the openApiDocs/v1.0/Mail.yml under the PowerShell repository as the OpenAPI to generate an SDK for. By default this configuration will output the generated files in a graphdotnetv4|graphjavav4|graphtypescriptv4 folder located in the parent folder this repository is cloned in.

Selecting the language you want to generate an API client for in the Visual Studio Debug tab and hitting F5 will automatically build, start, and attach the debugging process to Kiota.

Samples

You can find samples of clients generated with Kiota in the Kiota samples repository.

An example of an application that is calling multiple API can be found in the KiotaApp repo
