Hi All,

I need your help in finding the values of certain fields that exist in the REST API but seem unavailable or problematic in GraphQL. The specific fields are:

  1. source_name – While this field exists in GraphQL, attempting to include it in the query results in an issue.
  2. checkout_id – I couldn’t locate this field in GraphQL.

Could you guide me on how to retrieve or work with these fields in GraphQL, or confirm if they are unsupported?

Thank you in advance for your assistance!
