Manage Duplicates is a great and smart tool that provides us with many interesting insights about potential duplicates. We found many cases that need different approaches for solving them using Manage Duplicates recommendations. It would also be great to make this list accessible via API to make some attempts of automated processing of some cases we found. We currently consider private app or custom code actions to process paires of potential duplicates found by Manage Duplicates tool and we believe that having API for connection to this tool might help us a lot. Thank you for reviewing this idea ---

Having access to the doppelganger API that hubspot uses inside the app to search and return duplicate canidates is what we need as developers. I hope this could be simple for HubSpot to turn into a public API. [https://app.hubspot.com/api/doppelganger](https://app.hubspot.com/api/doppelganger)
