I have an esp-07 and I try to activate an applet on ifttt. I made several version of the program but none of them seems to work and I dont understand why.
I connect to wifi, I am able to post data on thingspeak but when I want to execute an applet on ifttt it does not work and I don't have any error message.
I check with API tester and it works, it call the applet. I simplfied the code and here a version I use to debug:
(I replaced the ssid, password, eventname and ifttt_key)

Code: Select allconst char* ssid     = "myssid";
const char* password = "password";
const char* host = "maker.ifttt.com";

void setup() {
  Serial.begin(115200);
  delay(100);

  // We start by connecting to a WiFi network
  Serial.println();
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);

  WiFi.begin(ssid, password);

 while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
}
void loop() {

  WiFiClient client;
  const int httpPort = 80;
  if (!client.connect(host, httpPort)) {
    Serial.println("connection failed");
    return;
  }



   Serial.print("Requesting POST: ");
   // Send request to the server:
   client.println("POST /trigger/eventname/with/key/mykey HTTP/1.1");
   client.println("Host: maker.ifttt.com");
   client.println("Accept: */*");
   client.println("Content-Type: application/x-www-form-urlencoded");
   client.print("Content-Length: 0");
   

   delay(500); // Can be changed
  if (client.connected()) {
    client.stop();  // DISCONNECT FROM THE SERVER
  }
 Serial.println();
  Serial.println("closing connection");
  delay(5000);
}


The wifi connect, if I try on api tester the command : https://maker.ifttt.com/trigger/eventna ... /key/mykey it works and the header is:
POST /trigger/eventname/with/key/mykey HTTP/1.1
Host: maker.ifttt.com
Accept: */*
User-Agent: Rigor API Tester
Content-Length: 0
Content-Type: application/x-www-form-urlencoded

So it seems what I am posting Is OK.

Does anyone see what I am doing wrong ?

Thanks for your help
