Adding images to Metafield with API

[mike_casey_2]

I am trying to populate a Metafield through the API.  

I look through the product images and find the one that I want.  I copy the source and use it in my metafield call.

When I go to update the metafield, it gives me an Error posted below.

Using 

admin/api/unstable/products/${prodId}/metafields.json API point

Not sure what is going on.  Let me know if you need any more information.

Hi @mike_casey_2 ,

Thanks for your post. 

From what i can see it looks like you are trying to set an image URL as the value for a file_reference which isn't valid. It should be a GID pointing to an image or file. 

responseType: 'json',
data: '{"metafield":{"value":"https://cdn.shopify.com/s/files/1/1190/2562/products/STAND-V000DC_04.jpg","namespace":"my_fields","key":"text_column_1_image","type":"file_reference"}}',
type: 'application/json'
},

Hope This Helps,
Ben

Thank you for your response.

I get the same error when using the GID.  Posted below is the data I am sending and the endpoint.

Strangely enough, if I change the file path from /ProductImage/  to /MediaImage/ no error is thrown, but the path does not actually exist.

config: {
      transitional: [Object],
      adapter: [Function: httpAdapter],
      transformRequest: [Array],
      transformResponse: [Array],
      timeout: 0,

      xsrfHeaderName: 'X-XSRF-TOKEN',
      maxContentLength: -1,
      maxBodyLength: -1,
      validateStatus: [Function: validateStatus],
      headers: [Object],
      method: 'post',
      url: 'https://redacted.myshopify.com/admin/api/unstable/products/4786340200547/metafields.json',
      responseType: 'json',
      data: '{"metafield":{"value":"gid://shopify/ProductImage/29558218326115","namespace":"my_fields","key":"text_column_1_image","type":"file_reference"}}',
      type: 'application/json'
    },

[mike_casey_2]

OK, I did some testing...

When I upload an image either through the GUI or API, it creates an image with the MediaImage path that I can use in my API call and it will load the correct image for my Metafield.

But the file Id for the ProductImage path and MediaImage path are different.  Where can I find the MediaImage gid path?
