Add media on Metafield Product - Get error : must be a file reference string.

[thinkcloud]

Hello everyone, I'm trying to send an image of my products (product/images[1]/admin_graphql_api_id in a product metafield, but I get the error "must be a file reference string", I don't understand where is the problem coming from, does anyone have any advice?

My API REST call is : POST 

"https://xxx.myshopify.com/admin/api/2023-10/products/ID/metafields.json"

Hey @thinkcloud 

Checking with the metafield folks and will report back.

Hey @thinkcloud 

They said:

Couple of issues:

• Reference type metafields are not supported in REST
• GID seems to be inaccurate. It needs to be a media GID, for example: gid://shopify/MediaImage/...
gid://shopify/Video/...

Thanks, and how to retreive MediaImage with REST API ?
I only GET ProductImage 😕

Hey @thinkcloud 

Unfortunately I think these are only accessible via the GraphQL API.

{
  products(first:10) {
		nodes {
			id
			media(first:10) {
				nodes {
					id
				}
			}
		}
	}
}
