‘Invalid Parameter’ means one of the parameters are missing or invalid, for example:
- a date range
- passing of a string where a number is expected
- invalid character like the ‘new line char’ in a string, etc.

- a bad implementation when doing requests to the ecommerce API
Adding the following timestamp parameter to the end of your ecommerce command(s) can rule out whether it is cache issues:
The unique_identifier should be a unique number not used on any other requests (usually it’s the actual timestamp of the request).
