Get User Info

There are several ways to fetch information about a user:

Using their user ID, you can get their email ID, time joined, and metadata that is saved in the user metadata recipe.
Lastly, you can get the user's session information and access token payload from their session handle (offline mode), or from the currently logged in session object (online mode).

Fetching information using the user's email#

NodeJS
GoLang
Python
Other Frameworks

Use the listUsersByAccountInfo function to retrieve a user's data, specifying the account type and providing the user's email as criteria.

import supertokens from "supertokens-node";

async function getUserInfo() {
    let usersInfo = await supertokens.listUsersByAccountInfo("public", {
        email: "[email protected]"
    });

    /**
     * 
     * userInfo contains the following info:
     * - emails
     * - id
     * - timeJoined
     * - tenantIds
     * - phone numbers
     * - third party login info
     * - all the login methods associated with this user.
     * - information about if the user's email is verified or not.
     * 
    */
}

You can get a user's information on the backend using the GetUserByEmail and GetUserById functions:

import (
    "fmt"

    "github.com/supertokens/supertokens-golang/recipe/emailpassword"
)

func main() {

    // Note that usersInfo has type User[]
    // You can learn more about the `User` object over here https://github.com/supertokens/core-driver-interface/wiki
    userInfo, err := emailpassword.GetUserByEmail("public", "[email protected]")
    if err != nil {
        // TODO: Handle error
        return
    }
    fmt.Println(userInfo)
    //...
}

Asyncio
Syncio

You can get a user's information on the backend using the list_users_by_account_info function:

from supertokens_python.asyncio import list_users_by_account_info
from supertokens_python.types import AccountInfo

async def some_func():
    # Note that users_info has type List[User]
    user_info = await list_users_by_account_info("public", AccountInfo(email="[email protected]"))
    print(user_info)

    # 
    # user_info contains the following info:
    # - emails
    # - id
    # - timeJoined
    # - tenantIds
    # - phone numbers
    # - third party login info
    # - all the login methods associated with this user.
    # - information about if the user's email is verified or not.
    #

You can get a user's information on the backend using the list_users_by_account_info function:

from supertokens_python.syncio import list_users_by_account_info
from supertokens_python.types import AccountInfo

def some_func():
    # Note that users_info has type List[User]
    user_info = list_users_by_account_info("public", AccountInfo(email="[email protected]"))
    print(user_info)

    # 
    # user_info contains the following info:
    # - emails
    # - id
    # - timeJoined
    # - tenantIds
    # - phone numbers
    # - third party login info
    # - all the login methods associated with this user.
    # - information about if the user's email is verified or not.
    #

Multi Tenancy

Notice that the first argument of the above function is "public". This is the default tenantId which means that SuperTokens will return information about the user whose email is "[email protected]" in the "public" tenant.

If you are using our multi-tenancy feature, you can pass in a different tenantId to get information about a user in a different tenant.

Fetching information using the user's ID#

Retrieve the user's ID by calling:

the getUser function for NodeJS
the GetUserById function for GoLang
the get_user_by_id function for Python

Refer to the code snippets below for example usage:

NodeJS

Using the user metadata recipe#

Checkout the user metadata recipe docs which shows you how to save and fetch any JSON object against the user's ID. You can use this to save information like the user's name (first_name and last_name) or any other field associated with the user.

Getting information from the user's session#

The user's session contains their user ID and the session's payload. You can access this on the backend and frontend as well as whilst the user is online or offline.

More information about this can be found in the session docs.
