Fetching Credential Details

To read the details of the user credentials, you need to implement the FetchCredential operation. This section walks you through:

• Preparing the Request Message
• Invoking the Web Service
• Interpreting the Response Message

Preparing the Request Message

The FetchCredentialRequestMessage is used to read the credential details. The input elements for enabling the credentials are same as that explained in the "Creating Credentials" section. For more information about each element, refer to the tables listed in the "Creating Credentials" section.

Invoking the Web Service

To read a user’s credential information:

1. (Optional) Include the authentication and authorization details in the SOAP header or in the additionalInput element of the FetchCredential operation. See chapter, "Managing Web Services Security" for more information on these details.
2. Use the userName and orgName elements to fetch the details of the user whose credentials must be fetched.
3. Depending on the type of credential you want to fetch, use the respective <CredentialName>Input element to obtain the credential information.

   The input required for each credential is different. For example, password is needed for Password as well as ArcotID PKI, while questions and corresponding answers are required for QnA credentials.

4. (Optional) If you are implementing a plug-in, then invoke the additionalInput element type to fill the additional input.

   This type provides the additional information that is set as a name-value pair.

5. Use FetchCredentialRequestMessage and construct the input message by using the details obtained in preceding steps.
6. Invoke the FetchCredential operation of the ArcotWebFortIssuanceSvc service to fetch the credentials.

   This operation returns an instance of the FetchCredentialResponseMessage that includes the credential and transaction details.

Interpreting the Response Message

For successful transactions, the response message, FetchCredentialResponseMessage returns the elements explained in the table containing information about the elements that the response message, CreateCredentialResponseMessage, returns. These elements are included in the SOAP body. If there are any errors, then the Fault response is included in the SOAP body. See appendix, "Error Codes" for more information on the SOAP error messages.
