# Merge two identities (mergeIdentities)

`POST /mergeIdentities`

Merges a "toRetire" source identity into a "toSurvive" source identity. After a merge, the retired source is marked as merged and the surviving identity contains combined data. The response returns the surviving linkId. Note: only provider identities of the same type can be merged together (ie Practitioner to Practitioner, not Practitioner and Health Facility).
