Pass x-api-key in your HTTP header

• The GreenSwapp API uses API keys to authenticate requests. You can get API keys by contacting GreenSwapp.
  
• Your API keys carry many privileges, so be sure to keep them secure! Do not share your secret API keys in publicly accessible areas such as GitHub, client-side code, and so forth.
  
• Every incoming request to the API must contain an API key. You can use API key by passing the API key as the x-api-key in HTTP header of each incoming HTTP request.
  
• All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail.
