If the metafield you are trying to update is not created in your store, then Stock Sync will create the metafield but Adding snippets into Shopify Theme Liquid needs to be done manually.

For the metafield, there are many metafield that you can apply as metafield 1, 2, 3,... and so on. And there also provided a few settings as well. So, let's look at the explanation of the setting below:

1. Metafield Namespace and Key

Namespace is a category or container that differentiates your metadata from other metafields.

You need to enter the Key for metafield as your choice. You can choose any name that is preferable for you.

For example:

From the Shopify admin, you can see that these are the namespace and key.

Namespace: my_fields

Key: ssff

Namespace and Key are separated by .

Shopify UI added the product owners into the key. So it will be products.namespace.key

You want to put the instruction washing for the clothes product. So, you can use this metafield as the reference for it.

Namespace: washing_machine

Key: clothes

Namespace and Key are separated by .

For namespace min 2 character and key min is 3 charactersThe character limit error will display as below.

Metafields provided TWO components :

  • namespace - A category or container that differentiates your metadata from other metafields
  • key - The name of the metafield

Namespaces will be used to group different metafields, keys will be used to reference our information, and values will contain our unique content.

To view the accurate format of metafield, please do open your feed file via notes or notepad so that can see it clearly. If open via excel, it could change some of the value formatting such as numbers and dates. 

For example, if you have a metafield like this:

1 day
2 days

The Namespace is the Estimated Time of Arrival, the Key is ETA and the Value will attached to the Product of the Variant according to the metafield owner.

For the metafield type, you should choose the correct data type. The data type also must be the same in Stock Sync and Shopify. If not, it will get an error.

Default value if the cell is blank. If the feed has a blank cell for a product, then the default value will be added to the metafield value instead. The default value can't be left blank.
