# Link two identities (linkIdentities)

`POST /linkIdentities`

Links two existing identities together without retiring either source. This is typically used when you determine that two separate source identities belong to the same real-world provider, and they should be represented as a single link ID. Note: only provider identities of the same type can be linked together (ie Practitioner to Practitioner, not Practitioner and Health Facility).
