Magento 2 some hourly help.

I have a problem with errors in the code my former developer did.
I need some help for an hour or two immediately

Parameters in API is not correct
One are must be changed as it has 3 varaibles and not one.

I can code most of it except input parameters and the array that is received from another function.

pretty small job.

Start immediately
