I’m not aware of such a service, but I think it’s good idea. Perhaps a simple flag in the request, e.g.
´´´
{
"creator": "userName",
"notificationAddresses": [
"userEmail@example.org"
],
"sendNotification": true,
"format": "SIMPLE_CSV",
"test": true,
"predicate": {
...
and then return 201 if successful? I guess it might also be set in the header to test the validity of the entire payload.
@MattBlissett, any comments or thoughts?
