Hi. Good day.  I'm trying to upload an image using esp8266 which is a wifi module. My code

if (client.connected()) {
Serial.println("Connected");
client.println("POST /v1_1/dciqwty6f/image/upload HTTP/1.1");
client.println("Host: https://api.cloudinary.com");
client.println("UPLOAD_PRESET: lokttils");
client.println("Content-Type: Image/jpeg; boundary=AaB03x");
client.println("file: http://res.cloudinary.com/demo/image/upload/remote_media/commons/2/29/Marcelo_Facini.jpg");
client.println();
client.println("Connection: close\r\n\r\n");
delay(5000);
}

but the response am getting is

{"error":{"message":"Missing required parameter - file"}}

  Hi,

  Thanks for reaching out.

  Hardly an Arduino expert but judging from the error it looks like you're passing the parameters (file and upload_preset) in the headers and not in the BODY. 

  You can try something like this - 

  String PostData = "file=<image>&upload_preset=<preset>";

  //After headers and Host

  client.println(Postdata);

   

  Also, worth checking out the HTTP client.

  (As suggested in this GH thread)

   

  Hope it helps.

   

  Best,
