API Key Authentication

The API Key Authentication is an alternative to Http Basic Authentication, that improves authentication security by avoiding the usage of user's credentials. Instead of, a random generated unique key, called the API Key, is used. This key does not contain any sensitive data, so it may be stored on 3rd party location. 

As in the Http Basic Authentication, also a API Key has to be provided with any request as Authorization header.

Authorization: "apiKey {put-API-key-here}"

Replace {put-API-key-here} with your generated API Key. Example:

Authorization: "apiKey HT5tI2DfA9TviUmPwzw8eePVW0zgMvfUyHwEQn5iiHmIT7BAjSKEAlopnqCXKhgcXsjTgcZbg4KeaZyGytTVL"


There are two types of API Key:

  • user key, which current user generates for himself. This key only authenticates the user. Request, that access company recources, requires Company identification.
  • user-and-company key, which current user generates for any user and current company. This key authenticates the user and includes company identification. Additional Company identification in request is not allowed.
