   These can be filtered out with `apolloConfig.formatError` if you need to process them, but do not want them returned over the GraphQL API.
 - `queryLimits` (default: `undefined`): Allows you to limit the total number of results returned from a query to your GraphQL API.
   See also the per-list `graphql.queryLimits` option in the [Schema API](./schema).
+- `path` (default: `'/api/graphql'`): The path of the GraphQL API endpoint.
 - `apolloConfig` (default: `undefined`): Allows you to pass extra options into the `ApolloServer` constructor.
   - `playground` (default: `process.env.NODE_ENV !== 'production'`): If truthy, will enable the GraphQL Playground for testing queries and mutations in the browser.
     To configure behaviour, pass an object of [GraphQL Playground settings](https://github.com/graphql/graphql-playground#settings). See the [Apollo docs](https://www.apollographql.com/docs/apollo-server/api/apollo-server/#constructor) for more supported options.
