FileMaker 17 API -- sort by recordId instead of fieldName

Question

I'm using curl to connect a FileMaker 17 database.

I can do a query and sort on a given fieldName, so for instance, I can do something like:

"sort":[
    {"fieldName": "Work State","sortOrder": "ascend"},
]

What I cannot do, but what I'd like to do is something like:

"sort":[
    {"fieldName": "recordId","sortOrder": "ascend"},
]

recordId is not a "field", and so the above does not work. The syntax for this is not readily apparent in the FM documentation.

Answer 1

I'm going to answer my own question, by saying that it's impossible to descend sort on a record ID within filemaker. Having to add another field is a workable solution, but in terms of the goal of documenting code in API it is not possible to descend sort on a record ID
