Your application needs to identify itself every time it sends a request to the Crowdin API by an API Key with each request. Each Crowdin project has its own 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 secret! It should be guarded just as you would your regular account password.
Here's an example and principle of API request URI forming.
Typical API call URL looks like this: http://api.crowdin.net/api/project/. First placeholder (keyword in brackets) holds project identifier and action needed (download as shown in the example). API access key is specified as a URI parameter.
