OTP Service

Overview

OTP Service is a core service that is available on the DIGIT platform. The service is used to authenticate the user in the platform. The functionality is exposed via REST API.

Pre-requisites

Before you proceed with the documentation, make sure the following pre-requisites are met -

• Java 17

Key Functionalities

egov-otp is called internally by the user-otp service that fetches the mobile number and feeds to egov-otp to generate the 'n' DIGIT OTP.

Configuration Details

The below properties define the OTP configurations -

a) egov.otp.length : Number of digits in the OTP

b) egov.otp.ttl : Controls the validity time frame of the OTP. The default value is 900 seconds. Another OTP generated within this time frame is also allowed.

c) egov.otp.encrypt : Controls if the OTP is encrypted and stored in the table.

Deployment Details

1. Deploy the latest version of egov-otp service.

2. Add role-action mapping for APIs.

Integration Details

Integration Scope

The egov-otp service is used to authenticate the user in the platform.

Integration Benefits

• Can perform user authentication without impacting the other module.

• In the future, this application can be used in a standalone manner in any other platforms that require a user authentication system.

Integration Steps

1. To integrate, the host of egov-otp module should be overwritten in the helm chart.

2. /otp/v1/_create should be added as the create endpoint. Create OTP configuration API is an internal call from v1/_send endpoint. This endpoint is present in the user-otp service and removes the need for explicit calls.

3. /otp/v1/_validate should be added as the validate endpoint. The OTP configuration end point validates the OTP with respect to the mobile number.

4. /otp/v1/_search should be added as the search endpoint. This API searches the mobile number and OTP using uuid - mapping uuid to OTP reference number.
