@codan84 what did you end up doing ?

@sofisl did you have time to look into this ?

I ended up using fetch and hitting your APIs directly

Nor can I see any reference to that in https://github.com/googleapis/google-auth-library-nodejs

I haven't tested this myself yet, but tracing through some of the dependencies that the client library pulls in, you can use google-auth-library to create a JWT AuthClient instance using [fromAPIKey(apiKey: string, options?: AuthClientOptions)](https://github.com/googleapis/google-auth-library-nodejs/blob/7dbedff829be093dad0a2da32f0ab12862d473bc/src/auth/googleauth.ts#L812]

This can then be injected into AddressValidationClient to override the default auth mechanisms.

const options = {
  authClient: fromAPIKey("my-api-key"),
};
const apiClient = new AddressValidationClient(options);

I can confirm that this works. I was looking for any easy way to move from manual HTTP requests to the new Places SDK and here is how you can create the client:

import { v1 as PlacesApiV1 } from '@googlemaps/places';
import { JWT } from 'google-auth-library';

const { PlacesClient } = PlacesApiV1;
const authClient = new JWT();
authClient.fromAPIKey('my-api-key');
const placesClient = new PlacesClient({
    authClient,
});
