  title: Prisma Client Upsert a Record
  summary: Look up a record by its unique key, then upsert it so it is created when missing or updated when present.
  description: >-
    A common Prisma Client data pattern expressed against the REST facade. The
    workflow first attempts to read a record by its unique id, branches on
    whether it was found, and then issues an upsert that creates the record when
    no match exists or updates it when it does. The upsert carries both the
    create and update payloads alongside the where condition so a single call
    handles both branches. The Client API is a local library facade and does not
    require an Authorization header. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
