Http POST request parsing data using just the url

Projects Programming

Hey!

Is it possible to do a POST request using just the url to parse a value using the HTTPclient.h library? I am able to do it using POSTman. But I can't using my ESP32. What am I missing?

Kind regards Alexander

void loop() {
  //Send an HTTP POST request every 10 minutes
  if ((millis() - lastTime) > timerDelay) {
    //Check WiFi connection status
    if(WiFi.status()== WL_CONNECTED){
   if(WiFi.status()== WL_CONNECTED){   //Check WiFi connection status
  
   HTTPClient http; 
   String value = "99"  
  
   http.begin("http://randomurl.com/arrive/"+ value);  //Specify destination for HTTP request
   http.addHeader("Content-Type", "x-www-form-urlencoded");             //Specify content-type header
  
   int httpResponseCode = http.POST();   //Send the actual POST request
  
   if(httpResponseCode>0){
  
    String response = http.getString();                       //Get the response to the request
  
    Serial.println(httpResponseCode);   //Print return code
    Serial.println(response);           //Print request answer
  
   }else{
  
    Serial.print("Error on sending POST: ");
    Serial.println(httpResponseCode);
  
   }
  
   http.end();  //Free resources
   }
    else {
      Serial.println("WiFi Disconnected");
    }
    lastTime = millis();
  }
  }
  
}```

With a content type of x-www-form-urlencoded, the payload is in the body
