How to PUT repeated pair of data in single request?

I have a structure like this:
{
“code”: 0,
“text”: “”,
“error”: “”,
“data”: [
{
“name”: “add_byte_in”,
“value”: “100000000”,
},
{
“name”: “add_byte_out”,
“value”: “0”}]}
To modify it I’ve made this request:

PUT {URL}
raw/json:
{ “data”: [
{
“name”: “add_byte_in”,
“value”: “10”,
},
{
“name”: “add_byte_out”,
“value”: “10”}]}
And now I have an error “json: cannot unmarshal array into Go struct field .data of type SystemParam”
