In my store I have a product entitled "Sensor Monitoring Kit" that has a product Id of 6825986654393 and one variant of Id 40446347542713. I have one selling plan associated with this product which is selling plan Id 507642041 ("Delivery every 3 Days").
My question is, how can I get a list of all products in my store, the associated variants and selling plans via API? I am not sure if I can use the REST APIs, or if I must write a GraphQL query. If it is a GraphQL query, could I please get some assistance with the syntax?
