Unable to trigger webhook using at command

I am using ESP-01 module for WIFI communication :

AT+CWJAP="FTTH-0FC5","*******"
AT+CIPSTART="TCP","maker.ifttt.com",443
AT+CIPSEND=80

\r\nGET /trigger/help/with/key/MY_KEY HTTP/1.1\r\n
Host: maker.ifttt.com\r\n\r\n

output:

400 Bad Request

I'm no expert, but I think you're making a bad request in the code you didn't post

I have only use AT Commands ,there is no code written to the esp01 module
