In my GraphQL server I want to fetch data from a third party GraphQL endpoint and return the same data from it’s resolver. Is schema delegation used to achieve this?

Hi @ravish-goel 👋 , there are a couple options you have here. You can accomplish this with [Apollo Federation](https://www.apollographql.com/docs/federation/federated-types/overview) and you can combine the remote 3rd party endpoint. You can try this out with `rover dev` or a Cloud Router instance.

**Using the Cloud Router - _use this if you have your GraphQL server hosted_**

1. [Create your supergraph with GraphOS](https://www.apollographql.com/docs/graphos/quickstart/cloud). You can use the 3rd party endpoint as your first graph  
_Note: you might need to [configure your cloud router](https://www.apollographql.com/docs/graphos/routing/cloud-configuration) for authentication rules if the 3rd party API requires it_
2. Navigate to the “Subgraphs” tab in Apollo Studio and add your GraphQL server (see image)

3. Once you’ve added your subgraph, head to the Apollo Explorer tab (the play button above the subgraphs tab) and try running a query across subgraphs

**Using `rover dev` - _use this if your GraphQL server is only available locally (currently in development)_**

1. Install [`rover`](https://www.apollographql.com/docs/rover/getting-started)
2. In a terminal window, run `rover dev --name=3rd-party --url=https://3rd-party.com/api/graphql` (make sure to replace the URL with your 3rd party endpoint)  
_Note: if the 3rd party endpoint doesn’t support introspection, you can use a local schema file and add --schema=schema.graphql to the above command. You may also need to [configure authentication](https://www.apollographql.com/docs/rover/commands/dev#advanced-configuration) for `rover dev` if the 3rd party API requires it_
3. In a new terminal window, run `rover dev --name=my-service --url=http://localhost:4000` (make sure to replace the URL with your locally running GraphQL server
4. Open up [http://localhost:3000](http://localhost:3000) and try running a query across your graphs.

I hope this helps. If you want to dive into it deeper or walk through an example, we started up an [Apollo Discord server](https://discord.gg/graphos) and you can ping me (@watson) to talk more. Hope to see you there!
