Genio is an easy to use code generation tool that can generate API client libraries in multiple programming languages. Genio comes with in-built support for multiple API specification formats - WSDLs, WADLs and the Google discovery format but also allows you to plug in parsers for additional specification formats. It uses a simple templating system that allows easy customization of the generated code.

• Ruby 1.9.3 or above

gem install genio

With genio installed on your local machine, run

genio <java|php|dotnet> --schema=path/to/specification [--output-path=output/directory]

With the --schema argument option, Genio will attempt to guess the specification type based on the file extension of the argument. If you follow non-standard naming convention for your files, please use the --wsdl / --wadl / --json-schema arguments instead.

Once you have generated source files with genio, you can use them in your project in conjunction with PayPal's core SDK libraries. You can take a look at the sample hello world projects and read language specific instructions here.

Genio comes with templates for the following programming languages. Support for other languages to follow soon.

• java
• dotnet
• php

• WADL (--wadl=path/to/schema.wadl)
• Google discovery format (--json-schema=path/to/schema.json)
• WSDL (--wsdl=path/to/schema.wsdl)

We have plans to add the following soon

• Automatic API reference generation from spec.
• Support for JSON schema Version 4 specification.

• Genio internals

We will be happy to accept contributions by way of templates for additional languages and parsers for other API specification formats. Please submit a pull request if you would like to contribute.
