I was hoping I might be able to get some help with placing a POST call from the MKR 1010 to a HTTPS REST endpoint. I'm using the ArduinoHTTP client and the WiFiNINA libraries to help me make this happen. The issues I'm having is with the certificates. I've used the Tool in the Arduino IDE to upload the cert on the board and I think that part is working. I've tried making calls to local servers that are not HTTPS and I can get things working. Maybe a working example or something like that? I could paste my code here but honestly I'm just testing everything and anything I can find on the web so my code is just lots of cutting and pasting. When I try to make a call to an HTTPS url I get a -2 response back. What has me so confused is that I can hit this very same endpoint from my Raspberry Pi without any problem so clearly I don't understand how the Arduino works when it comes to making REST calls.
Have you seen this example?
It's a GET call but it shows how to open an SSL connection, for the rest you can use any POST example for non SSL connections.
Thank you for posting and yes I have seen and tested that one. I used this one as a test to make sure that I was getting the cert tool working correctly. First I tried the sketch without uploading the cert via the firmware uploader. This test did not return any content. After I did upload a cert via the firmware uploader I was able to get this example to work. So I guess that's a cool thing right 
Let me try this test again using POST and I'll post my code here with the results that it returned. With that information folks might be able to offer more help. Again, thank you very much for posting a suggestion! Every little lead helps sometimes
