How to post a variable location correctly using HTTP and Arduino/ESP32 device

How to post a variable location correctly using HTTP and Arduino/ESP32 device

Hi everybody

I´m new on some Arduino/ESP32 with HTTP and TAGO, so thanks in advance for your help

I´m trying to post a variable to TAGO using HTTP Arduino example, a variable with some fixed data and LAT & LGN concatenate to location.

However, every method I've tried return a payload error because I´m sending a String and not an Object.

This is my post string concatenation on Arduino:
  2. String postData, postStr;

    String postData = "variable=serialNumber&value=" + String(serialNumber01)+ "&location=lat:" + String(valueLatitudeNow,8) + "&location=lng:" + String(valueLongitudeNow,8); 
  3.     postStr     = "POST /data HTTP/1.1\n";
  4.     postStr     += "Host: api.tago.io\n";
  5.     postStr     += "Device-Token: "+apiKey+"\n";
  6.     postStr     += "_ssl: false\n";
  7.     postStr     += "Content-Type: application/x-www-form-urlencoded\n";
  8.     postStr     += "Content-Length: "+String(postData.length())+"\n";
  9.     postStr     += "\n";
  10.     postStr     += postData;
  11.     client.print(postStr);
And this is what I´m seeing on Device Live Inspector:

19:27:53:
[POST] HTTP Request:
"From: 177.58.233.18 [Unknown] - Content-Type: application/x-www-form-urlencoded - Token Ending: b0e24"
"From: 177.58.233.18 [Unknown] - Content-Type: application/x-www-form-urlencoded - Token Ending: b0e24"
19:27:53:
Raw payload:
{ "variable": "serialNumber", "value": "FMIX5J40-110", "location": [ "lat:-23.48155800", "lng:-46.65259450" ] }
{ "variable": "", "value": "FMIX5J40-110", "location": [ "lat:-23.48155800", "lng:-46.65259450" ] }
19:27:53:
Connection refused, invalid payload:
{ "zodError": { "location": [ { "message": "Expected object, received array", "path": [ "location" ] } ] } }
{ "zodError": { "location": [ { "message": "Expected object, received array", "path": [ "location" ] } ] } }

I've tried many ways converting to a RAW JSON, reserialize, using the Payload parser, without success.

Someone could help me with an example in how to do that?

Thank you very much in advance!
