Need help sending GET request to IFTTT with ESP8266

Using Arduino Networking, Protocols, and Devices
1

I have an ESP8266 that I want to send off a GET request to ifttt.com to trigger an action. Here's the code that sends off the request:

WiFiClient client;
  if (client.connect("maker.ifttt.com", 80)) {
    Serial.println("Connected");
    
    String url = "/trigger/trap_triggered/with/key/{key}";
    Serial.print("requesting URL: ");
    Serial.println(url);
    client.print(String("GET ") + url + " HTTP/1.1\r\n" +
                 "Host: " + host + "\r\n" +
                 "Connection: close\r\n\r\n");
    Serial.println("request sent");
  }

*Note that in my actual code I've replaced {key} with my actual verified app key from ifttt.

The problem is that when the request gets sent off my ifttt service never receives it. I don't get any errors, everything seems to work fine on the ESP side. So I tested ifttt by putting the exact same request into a browser and it works perfectly every time. So it seems like my request is not making it from my ESP to ifttt.

Any thoughts on what the issue could be?

I recommend you try the 'ESP8266HTTPClient' library starting with the BasicHttpClient example. That will give you the HTTP status code which will tell you if the URL has a problem or the server has a problem.

Used the BasicHttpClient example you referenced and substituted in my network info and also my ifttt url. The code I'm getting back is 200, and using that example, I can see that ifttt did receive the request. So that works and I can use the setup from the example, but still not sure why my setup wasn't connecting....
