Welcome to the server API reference for ProcessOut!

The server API supports 5 languages (Node.js, Python, Ruby, PHP, and Go) and a REST API interface that you can access using a tool such as curl. See the page about setting up the APIs in the guide to learn how to obtain and install the appropriate library for your language.

The reference shows code samples for all 5 languages and also sample command lines using curl in the right-hand side of the page. Use the tab at the top-right of the window to select your target language.

To use the APIs, you will also need 2 project keys. These are text strings that uniquely identify your project to our endpoints. See the section about public and private keys in the guide to learn how to access and use these keys. Also, see the page about testing in the sandbox to learn how to modify the keys to access our safe testing environment.
