You can read from multiple child branches at various depths in a single request. For example, you can read Person, Phone, Phone Details1, Phone Details 2, Email, and Email Details 2 in a single request.

The following URL sample shows how to make a REST read request to get the Person record with row ID 1242, in addition to the Address Details 1 and Email child records:
