Patient Scheduling API | Labcorp APIs

Search for Labcorp patient service center (PSC) locations and bookable services, check appointment availability, and schedule, update, or cancel patient appointments.

Authentication

Requests reached through the Labcorp Aperture gateway authenticate with OAuth 2.0 Client Credentials (see Authentication). The gateway forwards your partner identity downstream; you do not set that header yourself.

Input Validation

Appointment endpoints validate patient email and address data. Whether validation is enforced or relaxed depends on partner type — see the Scheduling workflow guide for the full breakdown.
