Describe the feature you'd like to request

I would like to be able to call a different API endpoint from my Angular app if I need then the one that is configured in Amplify.configure.

I currently add a custom header:

Amplify.configure(awsConfig.adminApp, {
  API: {
   GraphQL: {
     headers: async () => {
       const currentSession = await fetchAuthSession();
       if (currentSession.tokens) {
         const idToken = currentSession.tokens.idToken?.toString();
         return { Authorization: idToken };
       } else {
         return undefined
       }
     }
   }
  }
});

and I am using this switch in my api graphql function:

  graphql<V>({ statement: query, variables, type, iam = false, familyApi = false }: queryInput) {
    if (familyApi) {
      Amplify.configure(awsConfig.familyApp);
    } else {
      Amplify.configure(awsConfig.adminApp);
    }
....

to swap the API config.

Describe the solution you'd like

What I am currently using, works, but it may not be the best way because I may be resetting the API configuration every time I do this.
A better option would be to have an option to override the graphQl endpoint in the (this.client.graphql(payload) function.
Because I am not sure I am losing my ID Token custom header if I run the configure again in my graphql function (I could add it).

Hi @mattiLeBlanc thanks for raising this issue. I've marked it as a feature request for the team to consider.

[stocaaro]

Earlier this year we added the ability to open different clients against different AppSync endpoints. This feature is documented here and you should be able to use it with the latest version of the library. I'll resolve this issue, but will monitor for updates, so if this doesn't fix your problem, post an update or a new issue.

Thanks,
Aaron
