'der Vater' and 'der Papi' both refer to the male parent. 'Vater' is neutral and fits almost all situations, including official or factual conversations. 'Papi' is affectionate, family-like, and colloquial. It is used especially by children or in a very close family setting. Learners might confuse the words because they refer to the same person. As a practical rule: in forms, reports, or normal conversations, you say 'Vater'. 'Papi' fits when speaking tenderly or childishly about one's own father.

The child calls for his daddy because he needs help getting dressed.
