Just a couple of days ago, I've implemented relaying of requests to Firebase for an esp8266 project & I would like to create a PR for this.

I ensured that I could indeed sent sms via twilio by using their twilio-sms.sh bash script.

However, when I try to use the https-relay, I get an Internal Server Error. (see below)

Any ideas?

Thanks for the service, but I can't it use for SMS.

First the links seem swapped on http://iot-https-relay.appspot.com/twilio.html
ESP8266 SMS (NodeMcu)
ESP8266 Calls (NodeMcu)
.

The only ifference seems to be the URI "/twilio/Messages.json" against "/twilio/Calls.json".
With Messages I get Error 500.
With Calls I get an automatic call but the body-text makes no sense.

Would be nice for a status update of the iot-https-relay.

Have a good time,
Samuel
