CQRS pattern: using command for external api call

I am aware of CQRS pattern wherein Query to be used for Reading data and Command to be used for updating the data.

In a peculiar case where the rest api is POST but not updating the data directly rather calling an external POST api of other system and passing the details.

In such case which one holds true - use Query or Command?

*Update *

System involves multiple DB. Not necessarily different DB for query and command however

Super simple. If you know for sure the call will not update or modify state or data, then it's a query, if it does (or might) then it's a command.

However, CQRS is often more about the physical structure of your system. You might have separate command and query databases... and that complicates the answer. It can have both logical and physical aspects.
