Hi there!! Below I post some code which might help. I have not actually posted data to Weather Underground so I am not certain if I can explain what is wrong. But, I took a stab at demonstrating the use of char arrays instead of String.

Also, here is an interesting and recent post regarding c-strings and char. Thanks to @gusgonnet and all the contributors, btw:

[https://community.particle.io/t/best-practices-with-c-strings-char-a-vs-char-b/59639](https://community.particle.io/t/best-practices-with-c-strings-char-a-vs-char-b/59639)

Now, for the code example. Try your version of the code below in your firmware and see what works for you:

```auto
const char myStationId16[16] = "KCAVISTA171";
const char myPassword16[16] = "XXXXXX";
char myDateUtc32[32] = "2000-01-01+10%3A32%3A35"; // over simplified, for sure!
char myWindDirection16[16] = "230";
char myOtherData16[16] = "blah_blah_blah";

// example of what the data should (might???) look like
char mySendData256[256] = "ID=YYYYYYYY&PASSWORD=XXXXXX&dateutc=2000-01-01+10%3A32%3A35&winddir=230&windspeedmph=12&windgustmph=12&tempf=70&rainin=0&baromin=29.1&dewptf=68.2&humidity=90";

// display example data buffer
Particle.publish("example_data", mySendData256, PRIVATE, WITH_ACK); 
delay(1000);

// let's build the send data field for real...
sprintf(mySendData256, "ID=%s&PASSWORD=%s&dateutc=%s&winddir=%s&myOtherDataHere=%s", myStationId16, myPassword16, myDateUtc32, myWindDirection16, myOtherData16);   
Particle.publish("test_data", mySendData256, PRIVATE, WITH_ACK); 
delay(1000);
    

```
