  title: Gingr Partner Invoices API
  description: 'Gingr''s Partner API for pet-care business management software (dog daycare, boarding, training, and grooming). The API is JSON:API-flavored - request and response bodies wrap resource attributes under a `data` object - and every request must send a `subdomain` header identifying the facility''s Gingr account plus an `Accept: application/vnd.api+json` header. Endpoints below are a curated subset (owners/parents, pets, bookings/reservations, services and configuration, invoices/payments, immunizations, report cards, and waitlist) drawn from Gingr''s official public OpenAPI document at https://docs.gingr.io/documentation/swagger.json (Gingr API v1.8.0), which documents 158 operations in total. This document is a representative subset, not a full mirror; consult the live swagger.json for every operation, filter, and field.'
