Five new open source API clients available for JavaScript, PHP, Ruby, and more!

Update: The API clients have received a number of updates since the first announcement. Read more about the status update on the libraries in a new blog post.

We have been busy building our libraries on GitHub to expand support for developers. Helping new ideas and services to be realized is very important to us, and we could not be prouder to see them deployed on UpCloud. Therefore, we are excited to introduce 5 new API clients to aid in integrating applications with our cloud services.

Five new API clients

The new libraries provide native access to the UpCloud API on the supported programming languages. They offer direct access to all of our features and services allowing greater control and possibilities for user side automation. With the new library additions, developing applications against our API is easier than ever.

Java API client

Java is one of the most popular object-oriented programming languages with straightforward portability for almost any platform. The Java API library will provide an easy starting point, for example, developing mobile applications.

JavaScript API client

JavaScript is one of the three core technologies that power the World Wide Web. The new API library allows for simple website integration with many opportunities.

PHP API client

PHP is a widely used server-side scripting language popular in web development. The code can be embedded into HTML code, or used in combination with various web template systems, web content management system, and web frameworks.

C# API client

C# is a common language for developing applications that run on the .NET Framework, a cross-platform, open-source, development platform, supported on Linux, macOS, and Windows. The C# client library will be especially useful for building desktop applications.

Ruby API client

Ruby is easy to use, object-oriented, open-source, scripting language with an elegant syntax that is natural to read and easy to write. Designed for general-purpose, Ruby has wide usage across the board for everything from web applications, to web servers themselves.

How to get started

Have a cool idea and some programming experience with a supported language? Get your coding hat on and dive right into the cloud! You can find instructions for installing the libraries and documentation about their usage in each repository. If you want to learn more about the UpCloud API, check out our getting started guide or take a look at the API documentation.

Want to make your own?

With the new additions to our API client libraries, there’s a good chance most will find a language for their use case. However, in case you would want to see another language supported we’ve got you covered. We have also included an OpenAPI Specification with which anyone can build an API client against the UpCloud API in a breeze.

UpCloud API Swagger specification

Swagger is the world’s largest framework of API developer tools for the OpenAPI Specification or OAS for short. It helps you develop the entire API lifecycle from design to deployment. Check out their documentation for the API development tools to easily quick start a new client.

Keep us in the loop!

Should you develop something with the new API libraries or Swagger, give us a shout on Twitter @UpCloud. We would love to hear what you guys are working on.
Exciting development times everyone!

  1. Where did the upcloud-api-spec go? It’s no longer publicly available on GitHub, it seems?

  2. Janne Ruostemaa

    Hi Timo, thanks for the question. After 3 years of busy development on our API side, the Swagger API spec was sadly outdated. So we’ve decided to pull the spec for the time being while we are working to update our developer tools.
