What integration strategy should an Architect recommend to de-duplicate Lead records against a 3rd-party MDM system optimally?

The optimal integration strategy in this context involves using an outbound message to the Master Data Management (MDM) system with a callback to Salesforce to mark duplicate Leads. This approach is well-suited for real-time data synchronization, ensuring that as Leads are created or modified in Salesforce, they are immediately checked against the MDM system for duplicates.

By sending an outbound message, Salesforce can communicate effectively with the MDM, allowing for the transmission of relevant Lead data that needs to be checked for duplicates. The callback functionality ensures that once the MDM system processes the incoming Lead data, it can notify Salesforce with the results—specifically, whether a duplicate record exists. If a duplicate is found, Salesforce can then take appropriate action, such as marking the Lead accordingly.

This method is advantageous because it supports real-time processing, which is critical for maintaining data integrity and ensuring that users are working with the most accurate data available. Additionally, leveraging a callback avoids the complexities associated with batch processes and allows for immediate feedback on the validation of Leads against the MDM system.

Other strategies may not provide the same level of immediacy or efficiency. For example, syncing the MDM system to a custom object in Salesforce requires additional setup and management, which can introduce latency in
