Access control to the API is always controlled by an API key that identifies a particular user. Usually, this API key is generated on the website and then copied into your third party application. It is now possible for registered applications to generate new API keys for each user on the fly by making a special API request.
Note: Each application using this approach is required to provide an application key to identify what application is requesting the API key. For more information on obtaining application keys please contact [email protected].
Note: If you already have an API key, you do not need to use the Login API.
