Is there any way of getting the constant Id or something to update a constant with the update constant smart service

I'm not aware of a way to do it within a single node, but perhaps you could do it using a gateway instead? You could two separate nodes that each point to different constants you want to update and have a gateway that uses your logic to decide which to execute.

Thanks for replaying Peter Lewis  I know i could  do it like that but  in my case i will manage around  30 companies  and that would  be a lot of work   i have to get token for all of them that´s why i wanted to do it this way 

If you're going to have that many items, I'd suggest creating a database table to manage the items instead of 30 constants. Then you can set up a value for each of your companies and just use a write to data store to update them whenever you need to.

Thanks a lot!
