400 BAD REQUEST while sending an HTTP request using wamp localhsot - api

Question

I am a student doing an internship as part of my college course, and I'm having a problem with using WAMP during sending an HTTP request.
I'm working on an RFID project with nodemcu8266 using arduino IDE, and I've to scan the tags and send the ID (ID of the card or the tag that the rfid scans) into my website using WAMP localhost server.
But after compiling the code I receive that problem '400 BAD REQUEST AS IT SHOWN BELOW'
here's my code for Arduino IDE:
//*******************************libraries********************************

}
delay(50);
//---------------------------------------------
//look for new card

return;//got to start of loop if there is no card present
}
// Select one of the cards
if ( ! mfrc522.PICC_ReadCardSerial()) {
return;//if read card serial(0) returns 1, the uid struct contians the ID of the read card.
}
String CardID ="";
for (byte i = 0; i < mfrc522.uid.size; i++) {
CardID += mfrc522.uid.uidByte[i];
}
//---------------------------------------------
if( CardID == OldCardID ){
return;
}
else{

}
//---------------------------------------------
// Serial.println(CardID);
SendCardID(CardID);
delay(1000);
}
//************send the Card UID to the website*************
void SendCardID( String Card_uid ){
Serial.println("Sending the Card ID");
if(WiFi.isConnected()){
HTTPClient http; //Declare object of class HTTPClient
//GET Data

//GET methode
Link = URL + getData;
http.begin(Link); //initiate HTTP request //Specify content-type header
int httpCode = http.GET(); //Send the request
String payload = http.getString(); //Get the response payload
// Serial.println(Link); //Print HTTP return code
Serial.println(httpCode); //Print HTTP return code
Serial.println(Card_uid); //Print Card ID
