`400 Bad Request` response:  
{“errorCode”:400,“message”:“invalid\_impersonation”,“additionalDetails”:"Invalid Staff Member Impersonation.

Why am I getting this response in the API calls, when I call the [https://api.servicem8.com/api\_1.0/staff.json](https://api.servicem8.com/api_1.0/staff.json) API

Thanks
