# Partially update a Person

**PATCH** `/persons/{personId}/`

Partially update the Person with new data.

To add a new email or phone to the Person, include a ContactChannel in the 'channels' array
without an 'id'.

To update an existing ContactChannel associated with the Person, include an 'id'. That existing
ContactChannel will be updated with the new email or phone. This will update any live Bundles
associated with the Person that are sending to that email (or phone).

If a ContactChannel does not include an 'id', but the email (or phone) matches an existing
ContactChannel, then that ContactChannel will not be changed.
