api - Redirect silently with express

Question

I'm working on a API project with NestJS (that uses express) and we'd like to maintain multiple versions of this API.

To do so, we decided to create an interceptor that will handle each request, use the api key to find the account it belongs to and be able to get the api version used by the account. Once we'll have the version, we would like to redirect the request to the specific version's endpoint.

For example, if a user using the version 15, he would request POST https://oursite.com/api/endpoint and the interceptor would redirect to POST https://oursite.com/api/v15/endpoint. I would like to redirect silently, to make it totally invisible for the user that this redirect mechanism exists. Is it possible with express?

Currently, the interceptor does something like this:

intercept(context: ExecutionContext, next: CallHandler): Observable<any> {
    const request = context.switchToHttp().getRequest();
    const apiKey = request.headers['Api-Key'];
    const account = repository.findByApiKey(apiKey);
    const version = account.version;

    const response = context.switchToHttp().getResponse();
    response.redirect(`/api/${version}/something...`);
    return next.handle();

but the redirection isn't silent.

Note: I also read that the redirect method could accept a status code, but I don't think it's what I need

thanks
