Once you have synced all child profile data, you will want to keep them up to date with any changes that occur in your system.
To update a child profile, perform a PUT request to the correct URL. This is the same URL that is used to fetch a full version of the profile. You can match this by using the URI template provided in the child profile index response.
curl \
-H "Accept: application/json" \
-H "X-Auth-Token: 54f958af0a4e0f272df3a76d63c14f79" \
-X PUT
-D 'child_profile[primary_home_language]=English&child_profile[phone]=555-555-5555'
https://localhost/api/child_profiles/94156
There will be no response body, but the Location header will contain a link to the updated profile.
