How to make a successful web request in monkey C?

You want to use https and not http.  If you search this forum you'll find certificate signers that work with CIQ.

If you look in the API doc the -1001 error is

"SECURE_CONNECTION_REQUIRED"

Another option might be to use BLE to talk to the rasberry pi.  See https://forums.garmin.com/developer/connect-iq/b/news-announcements/posts/would-you-like-some-raspberry-pi-with-your-connect-iq

Hi!

First of all, Thank you very much! Now it's working in the simulator! But I got -400 error on my watch. Can you send me a link about this api doc?

In eclipse, it's under the connect IQ menu..  In VS Code, it's under "Monkey C: View documentation"

There's also the web based doc: https://developer.garmin.com/connect-iq/api-docs/

Hey, could I ask how you got rid of the -1001 error? Wasn't sure what jim meant by using https instead of http.

You need to use https with a valid certificate and not http.

So sorry, not exactly sure what that means? What do you mean by certificate? Is this something separate from the code base I need to obtain? 

Google https and SSL certificate

Thank you, I was able to resolve the -1001 error but I've been having this issue now where I get a 404. I use curl and everything works when i make a manual post, but it just doesn't seem to receive post requests through my monkey c code even though its to the same url. Not sure if you had any experience with this?

Might not work for you, but I just changed http:// to https:// in the url when I was using OpenWeather API this solved -1001 error for me.
