I'm trying to add the orderNumber to a subscription so that I can have two to the same customer (I'm getting duplicate submission errors). I've gone to the playground here:
https://developer.authorize.net/api/reference/index.html#recurring-billing-create-a-subscription
entered my credentials, and added this at the bottom of the json just below the "billTo" block:
,"order": {"invoiceNumber":"123"}
This appears to match the documentation just below, but I get this error upon clicking send:
"code": "E00003", "text": "The element 'subscription' in namespace 'AnetApi/xml/v1/schema/AnetApiSchema.xsd' has invalid child element 'order' in namespace 'AnetApi/xml/v1/schema/AnetApiSchema.xsd'. List of possible elements expected: 'shipTo, profile' in namespace 'AnetApi/xml/v1/schema/AnetApiSchema.xsd'."
