This endpoint is in beta. Functionality may change without notice, support is limited, and use in production is not recommended. Your feedback is appreciated.

Updates a specific income record by ID. Pass only the fields to
change; omitted fields keep their current values. A field set to
null is stored as null. owner cannot be updated — since the
record's owner is echoed back on every read, a client sending a
full representation back unmodified still succeeds; only an actual
attempt to change it is rejected.
