When someone wishes you a Happy Birthday, you should reply with "Thanks a lot".
say'Thank you so much' with a cute smile in your face....
Thanks
Thank you. I appreciate the good wishes.
When a person gets birthday wishes on their wall, there is a small link just beneath the message called 'comment', and by clicking on that, one can write their reply.
Thank you.

Thank you? Danke.
a very happy birthday "Thank you, it was so kind of you to remember me" just an example
"Thank you, it was so kind of you to remember me"
"Thank you, it was so kind of you all to remember me in my this sweet day"
In France we usually reply "merci" with a smile. Indeed, or, "c'est gentil".
