Don't you know that is the DVD rom that is supposed to be used as cofee/can/soft drink holder, not the keyboard ? 😋
Now - you may be lucky to sort of get it sorted out if you rinse the keyboard in hot and clean water. The damage is already done. But it have to be done imediately after the spill, because soft drinks tend to settle over time - like glue or paint - and hence make it harder or impossible to make rid of the suggar (or whatever stuff that soft drink is composed of) so that it operates normal.
Best thing to do is probably to buy a new keyboard anyway, espechially if you cannot efford the keyboard to fail under importing gaming sessions.
