How can I check for water damage on my MacBook Air?

My macbook was on my bag, and my water bottle leaked a little. my macbook got some minimal moist outside, and no water got inside. any advice if I should check with apple if everything its ok with my macbook? my macbook so far is working fine and I dried up as much as I could with paper towels. but still scared of having any problems on the inside.

as it was closed the keyboard and track pad didn't get any water. I turned upside down and no water came out. was only slightly moist on the outside (as my backpack absorbed the water.
