We are trying to fetch various Sales Channel via GraphQL API. In Shopify UI we have 3 sales channel for a given date range but it seems to be fetching only one sales channel ‘Online Store’. The other two are not getting fetched via GraphQL API. Only online store and null value is being fetched via GraphQL API for sales channel field. Question is why are the other two sales channel not getting fetched via GraphQL API? How can we retrieve them?
