GraphQL

Marketplace, some privilege checks, and party invites share one HTTP endpoint:

POST /v1/profiles/me/uplay/graphql

The official Connect client sends persisted queries: operationName + variables + the SHA-256 of the stored query. The same route also accepts the GraphQL query source in place of the hash.

Request body

type PersistedQuery = {
  operationName: string
  variables: Record<string, unknown>
  query?: string // accepted instead of the hash
  extensions?: {
    persistedQuery: {
      version: 1
      sha256Hash: string
    }
  }
}

Send either extensions.persistedQuery or query. Connect PC sometimes POSTs an array of these objects instead of a single object; the response is then an array too.

Use standard headers with a marketplace (or party) ticket from ticket exchange.
