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.
Acquiring and Using an API Key
To find your project API key you have to login to your Crowdin account. Find the project, open Project Settings page and activate API tab.
Please note that almost all API calls require the Project Identifier (ID). You can find your project identifier right above the API key.
For every API request you make, you'll need to present the API access key as the main URI parameter to be authenticated. Keep the API key in secret! It should be guarded just as your regular account password.
Here's an example and principle of API request URI forming.
Typical API call URL looks like this: https://api.crowdin.com/api/project/. First placeholder (keyword in brackets) holds project identifier. API access key is specified as a URI parameter.
