Fetching User Attribute Values

The getQnAValues operation is used to read the values that are set for the user attributes present in the directory service. You can fetch the values for one or more attributes. This section walks you through the following topics related to this operation:

Preparing the Request Message

The following table lists the elements of the QnAValuesRequest message:

Invoking the Web Service

To fetch the values of user attributes:

  1. (Optional) Include the authentication and authorization details in the header of the getQnAValues operation. See chapter, "Managing Web Services Security" for more information on the header elements.
  2. Use the getQnAValuesRequest elements to collect the user, organization, and attribute information, as listed in the preceding table.
  3. Use the QnAValuesRequest message and construct the input message by using the details obtained in preceding step.
  4. Invoke the getQnAValues operation of the ArcotUserRegistrySvc service to fetch the values of the user attributes that are stored in directory service.

    This operation returns the QnAValuesResponse message that includes the transaction identifier, authentication token, and attribute values. See the following section for more information on the response message.

Interpreting the Response Message

The response message, QnAValuesResponse, returns the transaction identifier and the authentication token in the SOAP envelope header. The SOAP body includes the user attribute values for a successful transaction and the Fault response for an error condition.

See the following table for more information on the elements returned for a successful transaction. See appendix, "Error Codes" if there are any errors.
