How to use "allHeaders" option but only return row 1 (ie 2nd row)

[ozbrewer]

I'm calling ImportJSON and need to preserve the order of the json fields, so have to specify allHeaders option. But I only want to return the 2nd row from the urlfetch. Being a relative newbie to coding, I'm struggling to tell importJSON to preserve the order AND return only the 2nd row. Any help on syntax please?

Here is the function I wrote that creates the url (works) and passes it to the importJSON function specifying just the fields I'm looking for to be returned - but the order must be retained.

And yes, my cacheservice lines are commented out as I'm struggling to get them to work as well.

Thanks

}

Can close this issue, Learned that I can call the function from google sheets using Index and return only the 2nd row. I now call the function as follows: =INDEX(YFTechnicals(CBA.AX),1,0)
