Multiple meta key/value pairs

[mjacobsen4DFM]

To avoid multiple posts, is there any way to send multiple meta key/value pairs through the endpoint?
I expect something like this to work:
[
{
"key":"test_key",
"value":"test value here"
},
{
"key":"test_key2",
"value":"test2 value here"
}
]

No joy. I get "Missing parameter(s): key"
Is my JSON malformed for the request, or is it even possible?

Did you get any luck with this? Having the same issue...

Same here. Based on https://developer.wordpress.org/rest-api/reference/users/#create-a-user I believed that I could pass a json object of key/value pairs into the meta argument, but it yielded no saved usermeta in the database as of today with WP 4.8.2.
