Is this well written?
Hello!

I wanna know if this idea is right:

"He has written asking Santa Claus for a gift", implying that he has written a letter, but without mentioning that.

Should I write it in a different way? Thank you!

I’d use, “He wrote to Santa Clause asking him for a gift.”

It is just fine :)
