RCDevs OpenOTP SMS one-time passwords – integration manual

Here we describe how to setup RCDevs OpenOTP with SMSEagle for SMS one-time passwords.

SMSEagle is an offline hardware SMS gateway. Therefore no external connection to 3rd party system is required. All notifications are generated on-premise and sent directly to a cellular network.

This solution can be used in secure installations without Internet access.

SMSEagle Setup

RCDevs OpenOTP uses HTTP API requests (see details: API). All you have to do at SMSEagle is to create new user for API access at webGUI.

Create a new user in SMSEagle (menu Users > + Add Users, user access level: “User”).
Grant API access to the created user:
- click Access to API beside the newly created user
- Enable APIv1
- Generate new token (copy it for later use)
- Add access permissions in section APIv1 Permission for: send_sms, send_tocontact, send_togroup
- Save settings
