# Configure financing fields

`deals.update_terms_configuration`

Administer a pipeline's financing fields. Each supplied list replaces that list; omitted lists stay unchanged. Read deals.get_terms_configuration first. Required fields govern funding readiness; this does not change lender submission requirements or erase saved deal values.
