Clearing Metafield Data on Specific Product with GraphQL

[stats_marketing]

I need to "clear" values on specific MetaFields with Type "single_line_text_field" but only on specific products using the GraphQL API.

As I understand it we cannot send a blank value when running the `mutation metafieldsSet`, as I initially tried this but it won't take it.

If I try `metafieldDelete` mutation I am afraid that it will delete the MetaField everywhere.

I simply need to clear it on a specific set of Products/Product.

Any way to do this, as I am not seeing any way of doing this with the API?

Hi Stats_marketing,

Just to confirm, you'd like the same ability that existing in the admin where there's an option to clear a products metafield value, but just via the API?

I would like this!

Hi again,

I've looked into this more and it appears the metafieldDelete mutation will clear just the value of the specified metafield, but it won't delete the value of every instance of the metafield. 

The metafieldDefinitionDelete mutation will remove the metafield fully from the store.
