Error Code: 1021 (There is something wrong with your request headers)
HTTP status Code: 400
This error is all about you request headers.
In most cases you should send us at least:
- X-Auth-Token - if you are using api-key authorization
- Authorization - if you are using oAuth2 authorization
- Content-Type - this should be sent always, and for now it should be set to 'application/json'
If you get this error then please check you request headers!
