Arduino Sensor to Bubble API Endpoint

[asger.hansen]

@koechamos51

I managed to make a very basic connection via https to an app. Here is the script i used, which is a generic one from Arduino IDEthat i modified slightly:

/*
    HTTP over TLS (HTTPS) example sketch

    This example demonstrates how to use
    WiFiClientSecure class to access HTTPS API.
    We fetch and display the status of
    esp8266/Arduino project continuous integration
    build.

    Limitations:
      only RSA certificates
      no support of Perfect Forward Secrecy (PFS)
      TLSv1.2 is supported since version 2.4.0-rc1

    Created by Ivan Grokhotkov, 2015.
    This example is in public domain.

I created an app just for testing, and it actually works. I hooked it up to the endpoint like you said and send an email whenever there is a post request:

here is the API endpoint in bubble:

However, i would like to send data in the POST request as well, but am not sure how to add that in the header?

Another concern i have is adding authorization. I am not good enough at C/C++ yet. But do you maybe know how to?

Here is a picture of my setup right now, powered by a AA battery pack (judge all you want )
