SMS gateway
An SMS gateway delivers one-time codes by text message. Configure it from Manage environment → External services (see Overview). iCure supports four providers:
| Provider | Fields |
|---|---|
| Twilio | From (sender number), Sid, Token |
| OVH | From, App Key, App Secret, Consumer Key |
| Ring ring | Api Key |
| Swisscom | User name, Password |
The SMS gateway is what an authentication process uses to deliver SMS OTPs. Run it alongside an email gateway and choose the channel per process.
A process can only use a channel you've configured. With only an SMS gateway set up you can't create an email authentication process — add an email gateway first. See Authentication Processes (setup).
SMS gateways are Environment-Access only and shared across every project in the Environment. The Demo setup covers email only — there's no demo SMS, so SMS needs your own provider.
