We are building an API in-house and often are passing a parameter with multiple values.
They use: mysite.com?id=1&id=2&id=3
Instead of: mysite.com?id=1,2,3
I favor the second approach but I was curious if it was actually incorrect to do the first?

I guess it depends on technology you use, how it becomes convenient. I am currently standing in front of the same question using currency=USD,CHF or currency=USD¤cy=CHF
I am using Thymeleaf and using the second option makes it easy to work, I can then request something like: ${param.currency.contains(currency.value)}. When I try to use the first option it seems it takes the "array" like a string, so I need to split first and then do contain, what leads me to a more mess code.
Just my 50 cents :-)
