The following methods need to be implemented for sending requests ted for sending GET, POST, PUT and PUT DELETE requests to the HydraOMS backend:

language	ruby

def request_bpmwidget_backend(path, method = :get, parameters = {})
  request_params = {
      method:   method,
      url:      build_bpm_widget_path(path),
      user:     bpm_config.hbw_login,
      password: bpm_config.passwordhbw_token
  }
  
  if method == :get
    request_params.merge!({headers: {params: parameters.merge(bpm_parameters)}})
  else
    request_params.merge!({payload: parameters.merge(bpm_parameters)})
  end
  
 response(params) end
 
private
 
def response(params)
  response = RestClient::Request.execute(request_params)
end
  
{private
  
 code: response.code,
    headers: response.headers,
    body: response.body
  }
end

    userentity_type:     configurationparams[:loginentity_type],
    passwordentity_code: configuration    params[:passwordentity_code],
    headersentity_class: {       'Content-Type': 'application/json'
    }

end
 
params[:entity_class]
  }
end
  
def build_bpm_widget_path(path = '')
  URI.join(configuration[:url]bpm_config.url, '/widget/', path)
end

  }
end
 
def with_user_identifier(parameters)
  parameters.merge(
    user_identifier: session[:email] # email of current user
  )
end

  with_user_identifier(params.slice(*allowed_params))
end

end

GET and DELETE parameters should be passed as query part of url, e.g.:
