Failing to post data to Madavi

I have read that Wiki more than 10 times but not finding the answer I am looking for.
Below the json, reply from Madavi is 200 +(Sensor: esp8266-xxxxxxx
ok) so should be ok, but actually no data visible in their Figs. (using Postman for testing).
(X-Pin: … not required for Madavi, but I have tried with 0 or 1 but doesn’t work. Not needed to put values between “”).

Headers:
Content-Type: application/json
X-Sensor: esp-xxxxxxx

Body:
{
“software_version”: “test”,
“sensordatavalues”: [
{“value_type”: “SPS30_P0”, “value”: 7},
{“value_type”: “SPS30_P1”, “value”: 19},
{“value_type”: “SPS30_P2”, “value”: 15},
{“value_type”: “temperature”,“value”: 11},
{“value_type”: “humidity”,“value”: 75}
]
}
