Verify Order Exists

[urinud]

I'm importing orders into Shopify from several sources. In some cases I will need to check if an order already exists to avoid creating duplicates.
I have tried several ways to filter the order list but no luck there. Then tried to search using the GraphQL. So far the only field that I can set and an input that then allows me to search for it is the email. So creating a fake email that uniquely identifies the order I was able to search for it again. So far I haven't found any way to filter by "source_name", "source_identifier", "reference".
Does anyone knows a solution?

Thanks

Hey @urinud,

You could look into importing the order from the external systems with either tags or metafields to be searched for later: https://shopify.dev/docs/admin-api/graphql/reference/object/order?api[version]=2020-07
