Hi there! I am trying to change metafields data for any given product. The request succeeds but data isn’t updated. I have attached a photo to illustrate. [image.png] Here’s the text version of this code: mutation { productUpdate(input: { id: "gid://shopify/Product/8441259336", metafie…

Hi Arkadi, It looks like the issue you are running into here is that your mutation is missing the valueType parameter in the input. In this case, you will most likely want to set this to “INTEGER”.

Hi rchenx, I realize now that what you’re trying to do is update the value of an existing metafield on a product, which cannot actually be done with the mutation we are using here.

Hi folks, My mistake for suggesting the privateMetafieldUpsert mutation. You are correct in that it is the wrong thing to be using here. Instead, we should be using the productUpdate mutation as you originally thought, except instead of passing in the key as the identifier, we should use the actual…

I get a “ProductUpdate access denied” when trying your method. Is it possible to update public product metafield?

I got this error using the Shopify GraphiQL App from my shop page. (At the end I don’t mean to use it through an app but directly in a lambda function)

So if you go into the Shopify web admin for this shop and go into your logged-in user account. See what permissions are listed there. If you are using the Shopify GraphiQL app then the permissions flow from the logged-in user.

Access denied typically indicates that your API credentials don’t have the access scope permissions to perform the operation. If you edit the app permissions in the Shopify web admin and reauth your app then it should work.
