if i run the program through amendeus and sheety api the code is throws an error i have modified the API instead of Kiwi I used Amanda's flight files API because I'm not able to create the account in Kiwi I don't know the service will be stopped currently so if you guys have same error like me you are facing same error like me just let me know know i will attach this error and the ctepa if you add the another sheet it gives payment required error not able to complete this current project anyone facing same issues like me or some one found different api provider to build this just let me know.
