A tool that simplifies linking between directories. ## **What you can do with the Merge identity with addressless entities Tool** Use this tool and the API to merge (match/link) SaaS accounts with no email address into another directory. The tool also uses the API to automatically retrieve the PeopleID required for merging. Some accounts appear as unknown, such as GitHub accounts where no email address is available. This tool links that data to the correct directory more easily than doing so manually.
