Okay, so the following code is giving me the above error "Start date is invalid". Even when I have verified from various sources that it is a valid and well formatted start date. The res of the code has no problem since it is successfully returning the correct balance. I have searched every where but can't find a solution to this. Please help. Thanks!

I think your call to $this->encodeFields() (inside of call()) is causing your parameter values to be double-urlencode()'d. $this->encodeFields() is calling urlencode() on each of the elements in your $fields array; however, http_build_query() does this for you automatically. Therefore, you're probably ending up with STARTDATE=2016-02-24T00%253A00%253A00Z in your call to PayPal, when it should actually be STARTDATE=2016-02-24T00%3A00%3A00Z.
