All API requests need to be authenticated with your API keys. The
Authorization header will be used to provide the API key
If your API key is "a1b2c3d4e5", then the correct header will be:
Authorization: Apisecret a1b2c3d4e5
Please ensure that the Api secret key is always kept private
Note: Header value will always be prefixed with the word Apisecret followed by a space.
