The getMergeMaster method evaluates a list of Salesforce objects (SObject) and determines which record would serve as the master record after a merge operation. The method returns an SObject representing the master record based on the Plauti Deduplicate Merge Rules. This method is designed for preview purposes and does not perform the actual merge.

Apex example

This snippet queries duplicate Contact records, initializes the Duplicate Check API, and determines the master record using the getMergeMaster method. It logs the queried records, executes the master determination process, and outputs the identified master record or a message if no master record is found.

// Query the records to evaluate for merging
List<Contact> duplicateContacts = [
    SELECT Id, LastModifiedDate // Query all fields used for determining the master record
    FROM Contact
    WHERE Id IN ('003J8000007jigQIAQ', '003J8000007jigRIAQ', '003J8000007jigUIAQ')
];
System.debug('Queried duplicate contacts: ' + duplicateContacts);

// Initialize the Duplicate Check API
dupcheck.dc3Api dc3Api = new dupcheck.dc3Api();
System.debug('Duplicate Check API initialized.');

// Execute the method to determine the master record
System.debug('Executing getMergeMaster to identify the master record...');
SObject masterContact = dc3Api.getMergeMaster(duplicateContacts);
System.debug('getMergeMaster method executed. Result: ' + masterContact);

// Log the master record if found
if (masterContact != null) {
    System.debug('Master Record determined. Master Record ID: ' + masterContact.Id);
    System.debug('Master Record Data: ' + masterContact);
} else {
    System.debug('No master record could be determined.');
}
