Hello,

I'm using developer account. I have created a transient document using the API call and sent this agreement to get the signature. 

I want to track that agreement through get call. but got 

{

    "code": "PERMISSION_DENIED",

    "message": "The API caller does not have the permission to execute this operation"

}
