Contact Identity Tracker
========================

[](#contact-identity-tracker)

CiviCRM contacts are identified by their CiviCRM ID and, optionally, an external identifier, which is a single-calue filed on *Contact* entities.

This extension provides means for keeping track of multiple identifiers of different configurable types for *Contact* entities by adding a multi-value custom field group and an API for easily identifying contacts by those ID records.

Warning

**Incompatible with CiviCRM Core `5.71` prior to version `1.4`**

The extension is incompatible with CiviCRM Core starting from version `5.71.0`due to misuse of the API internally (which actually worked by accident). *Identity Tracker* version `1.4` fixes this incompatibility.
