The initialize method is called once when the runtime server starts. If there are any operations which may impede performance during runtime, such as loading a database table, they should be performed by this method.
The initialize method requires the following parameter:
configData - a map with key-value pairs of configuration data required by the callout.
Interact reads these values from the External Callout parameters defined in the Interact > Flowchart > External Callouts > [External Callout] > Parameter Data category.
If the initialize method fails for any reason, it returns CalloutException.
Return value
public void initialize(Map<String, String> configurationData) throws CalloutException
// configurationData has the key-value pairs specific to the environment
// the server is running in
// initialize scoreQueryUtility here
