Hi,

I am looking to use the REST API in order to delete items, and understand I need to use the .id field previously returned from a GET request in order to do so. My question is is this ID guaranteed to be the same for as long as the item exists? As far as I understand, when using regular RouterOS scripting, the IDs you get are only valid during the execution of that command or something.

Internal ID stays the same as long as object exists. It doesn't matter if it is api, rest api or console ID, is the same.

As far as I understand, when using regular RouterOS scripting, the IDs you get are only valid during the execution of that command or something.

@mrz is right about REST. And you're right about the CLI's "print" command - but those are "numbers=", not ".id=". To see the "*XX" form in .id in CLI, just add "show-ids" to any print to see same as REST.
The .id's can be also be used in CLI with "*" any place the 1... based numbers would work.

Alright. That explains it. Thanks!

Alright. That explains it. Thanks!

FWIW, the .id in REST are also the output of a "find" in CLI:
as REST:

"*2;*2b;*2c;*81;*93;*9d;*a2;*ab;*b1;*b2;*b3;*b4;*b5;*b6"

Basically it's print that has a "helper" to use relative numbers at CLI. I think since using *2b stuff for interactive use would get annoying.
