Making API calls from one Laravel app to another

I'm building 4 e-commerce sites for a client. These 4 sites will use the same code base and be deployed as separate applications. I'm then setting up a CMS that is using Nova to manage all the product data, users and orders from all the sites.

The CMS's database will be the single source of truth for all data across all the ecom apps. My approach will be that the CMS will expose an API for products to be listed on the ecomm sites by requesting a list of products via an API call to the CMS application.

I have a basic product function and route setup that looks something like this.

Route::get('products/{domain}', [ProductsController::class, 'getProductsByDomain']);

In my e-commerce controller, I'm trying to do something like this.

$products = Http::get('http://ecomm-admin.test/api/products/avid');

 return view('products')->with('products', $products);

Both apps are hosted locally right now using Valet and I'm getting the following error from my e-commerce application when trying to retrieve the products from the API call.

Illuminate \ Http \ Client \ ConnectionException
cURL error 6: Could not resolve:ecomm-admin.test (Domain name not found) (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for http://ecomm-admin.test/api/products/avid
