## Notes

When an array parameter is mentioned, the Rails convention of specifying array parameters in query strings is meant. For example, a ruby array like `foo = [1, 2, 3]` can be encoded in the params as `foo[]=1&foo[]=2&foo[]=3`. Square brackets can be indexed but can also be empty.

When a file parameter is mentioned, a form-encoded upload is expected.
