Downloading waypoint

While you can download waypoints by way of GC, you can't use them in a CIQ app.  So, you need to have your own way of setting them using something that that can be accessed by CIQ.  

JSON (if you are producing the location info). You can't use GPX*. CSV is more work than JSON.

You can add the location to the device's location list in IQ. But (as jim_m_58) says you can't do anything with the items in that list (except get the names) in your IQ app/widget.

----------------------------------

You could read the GPX as text and have your IQ app parse it but that's going to an awful amount of work).

I known that, I only need to get a small list of coord (lat/lon) for display/use in my app

???

Get from where?

Your only options are from a website or from settings.

(If it's from a website, it really should be JSON.)

as you said was wandering if it was better to get them from settigns or from a website (and in this case which format).

from what you said, seems that json is the best choice. maybe I will do both setting and website.
