How to implement User Defined Function using login API

In the previous post, we have seen implementing User defined functions using createAccount API.

Let’s check how to use the login or loginByEmail APIs to login a student account using the User Defined Function.

Example

You can login with loginStudentAccount function using username and password. emailLoginStudentAccount function accepts email and password as inputs to login a student account. It uses the login API to login a student Account.

type Query {
loginStudentAccount(email: String! password: String! ): AccessToken
  @tan(type:Groovy, inline: """return loginByEmail(email, password)""")
 
 emailLoginStudentAccount(username: String! password: String! ): AccessToken
  @tan(type:Groovy, inline: """return login(username, password)""")
}

Let’s execute the functions!

{
  loginStudentAccount(username:"hypi-user1",password:"[email protected]"){
        sessionToken
        sessionExpires
        errorCode
        errorMsg
    }
}
OR
{
  emailLoginStudentAccount(email:"[email protected]",password:"[email protected]"){
        sessionToken
        sessionExpires
        errorCode
        errorMsg
    }
}
#result
{
  "data": {
    "loginStudentAccount": {
      "sessionToken": "Auth-Token",
      "sessionExpires": 1628078182,
      "errorCode": null,
      "errorMsg": null
    }
  }
}
