How to integrate Crowdin with my deployment process?

Crowdin provides RESTful API with XML or JSON over HTTP using GET or POST methods. Listed below are all the available API methods, which allows you to create projects in Crowdin, add and update files, download translations or integrate localization with your development process.

Making requests

For every API request you make, you'll need to present the API access key as the main URI parameter to be authenticated. The authentication API key can be found on the project settings page - the "API" tab.

Keep the API key in secret! It should be guarded just as your regular account password.
