In this lesson, you will add a remote field to the Product model. Remote fields fetch data from a remote source in the context of a specific model entry. The field uses a value from the entry itself, in this case productSlug, as the argument passed to the external API, so the reviews returned are always scoped to that product.

This is different from a top-level remote field, which fetches remote data independently of any entry. That is covered in lesson 5.3.

#Add a remote field to the Product model

You will use the HyDemoAPI remote source configured in lesson 5.1 to add a Reviews field to the Product model.

1. Open the Product model in the Schema editor and from the right sidebar, add a REST remote field.

2. Fill in the following information:

   Field	Input
   Display name	Reviews
   API ID	Auto-completed. Leave as is.
   Remote source	HyDemoAPI is selected by default. Leave as is.
   Method	GET is selected by default. Leave as is.
   Return type	Select Reviews from the dropdown
   Path	/api/reviews/product/{{doc.productSlug}}

   The Path appends to the remote source base URL. {{doc.productSlug}} references the productSlug field on the current Product entry, which scopes the review data to that specific product.

3. Click Add to save.
