[solved]WEB API and ODATA and NAV 2013/R2 and NAV2016

Hello,

I'm developing a WEB API for sincronize an APP with NAV2013/R2 and NAV2016; I chose the protocol ODATA when I startd this project published a page 18 Customer like ODATA Service.

My question are

1) When I'm going to publisher a new record or I'm going to update a record using ODATA protocol by web service, the evaluation control, the trigger before insert/update value, etc will be it execute?

2) Have you never used ODATA to exchange data with an APP or other system device? Have you found some limit?

3) Is a possible to call a codeunit using ODATA protocol, passing IT a JSON like BigText?

thanks in advance
