SMS Relay
Sign in with your relay master key.
Sign in with your relay master key.
Messages appear here when your phone forwards them to this relay. Pair the phone under Settings.
In SMS Forwarder on the phone, add a Webhook sender with these settings. Set both the Secret and the Authorization header.
These only let a sender post messages. They are not your master key.
Turn this on after the phone sends both. While it is off, either one is accepted.
SMS Forwarder does not verify HTTPS certificates, so anyone who can intercept the phone's traffic (for example on hostile Wi-Fi) can copy the token. Rotate it if you suspect that, then update the phone.
