Unfortunately you will have to pass a comma seperated values as string to your SP and write SP accordingly.

If you think that your number of elements will vary greatly and that the number is quite big most of the time (say 1000 - 10000 elements in IN clause) you should seriously consider temp table for that.

But if you know that your number of calls vary between 1-1000 just use 1000 question marks if you are using prepared statements otherwise construct SQL on fly.
