What are the Sugar On-demand php ini values for post_max_size and max_input_vars?

Does anyone know the php ini values set for the Sugar On-demand environment for post_max_size and max_input_vars?

We have a client making a call to one of our endpoints with a lot of data and it is getting truncated for some reason. The data being sent is only 500KB but it has 3500 variables being sent, so my guess is the "max_input_vars" value is what is causing the issue but I need to confirm.

Thanks!
