Integration

Integration Scope

User data management and functionality to log in and log out into the DIGIT system using OTP and password.

Integration Benefits

Providing the following functionality to citizen and employee type users

Employee:
- User registration
- Search user
- Update user details
- Forgot password
- Change password
- User role mapping(Single ULB to multiple roles)
- Enable employees to login into the DIGIT system based on the password.
Citizen:
- Create user
- Update user
- Search user
- User registration using OTP
- OTP based login

Steps to Integration

To integrate, the host of egov-user should be overwritten in the helm chart.
Use /citizen/_create endpoint for creating users into the system. This endpoint requires the user to validate his mobile Number using OTP. The first OTP will be sent to his mobile number and then that OTP will be sent as otpReference in the request body
Use /v1/_search and /_search endpoints to search users in the system depending on various search parameters
Use /profile/_update for updating the user profile. The user will be validated (either by OTP-based validation or password validation) when this API is called
/users/_createnovalidate and /users/_updatenovalidate are endpoints to create user data into the system without any validations (no OTP or password required). They should be strictly used only for creating/updating user’s internally and should not be exposed outside
Forgot password: In case the user forgets the password it can be reset by first calling /user-otp/v1/_send which will generate and send OTP on the employee’s mobile number, the password can then be updated using this OTP by calling API /password/nologin/_update in which a new password along with the OTP has to be sent.
Use /password/_update to update the existing password by logging in. In the request body, both old and new password has to be sent. Details of the API can be found in the attached swagger documentation
Use /user/oauth/token for generating tokens, /_logoutfor logout and /_details for getting user information from his token
Multi-Tenant User: The Multi-tenant User functionality allows a user to perform actions across multiple ULBs. For example, an employee belonging to Amritsar can perform the role of Trade License Approver for Jalandhar by assigning a tenant level role of tenantId pb.jalandhar to him. Following is an example of such a user:

 {
        "id": 24226,
        "uuid": "11t0e02b-0145-4de2-bc42-c97b96264807",
        "userName": "xyz",
        "name": "abc",
        "mobileNumber": "9999999999",
        "emailId": "abc@gmail.com",
        "locale": null,
        "type": "EMPLOYEE",
        "roles": [
            {
                "name": "GP Admin",
                "code": "GP_ADMIN",
                "tenantId": "pb.massewal"
            },
            {
                "name": "Collector",
                "code": "COLLECTION_OPERATOR",
                "tenantId": "pb.lodhipur"
            }
        ],
        "active": true,
        "tenantId": "pb"
    }

If an employee has a role with state level tenantId he can perform actions corresponding to that role across all tenants

Refresh Token: Whenever the /user/oauth/token is called to generate the access_token , along with the access_token one more token is generated called refresh_token . The refresh token is used to generate new access_token whenever the existing one expires. Till the time the refresh token is valid the user won’t have to log in even if his access_token get’s expired, as it will be generated using refresh_token. The validity time of the refresh token is configurable and can be configured using the property: refresh.token.validity.in.minutes
