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.
• If the user logged in via a third party providers, you can get their profile info in the post sign up override along with the provider's access token. You can save this information in the user metadata recipe for later retrieval.
• 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

Important

For other backend frameworks, you can follow our guide on how to spin up a separate server configured with the SuperTokens backend SDK to authenticate requests and issue session tokens.

GoLang

You can get a user's information on the backend using the getUsersByEmail and getUserById functions:

import ThirdPartyEmailPassword from "supertokens-node/recipe/thirdpartyemailpassword";

async function getUserInfo() {
    // Note that usersInfo has type User[]
    // You can learn more about the `User` object over here https://github.com/supertokens/core-driver-interface/wiki
    let usersInfo = await ThirdPartyEmailPassword.getUsersByEmail("public", "test@example.com");
}

Python

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

import (
    "fmt"

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

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
    usersInfo, err := thirdpartyemailpassword.GetUsersByEmail("test@example.com")
    if err != nil {
        // TODO: Handle error
        return
    }
    fmt.Println(usersInfo)
    //...
}

Other Frameworks

Asyncio

from supertokens_python.recipe.thirdpartyemailpassword.asyncio import get_users_by_email

async def some_func():
    # Note that users_info has type List[User]
    users_info = await get_users_by_email("test@example.com")
    print(users_info)

Syncio

from supertokens_python.recipe.thirdpartyemailpassword.syncio import get_users_by_email

# Note that users_info has type List[User]
# You can learn more about the `User` object over here https://github.com/supertokens/core-driver-interface/wiki 
users_info = get_users_by_email("test@example.com")

Multi Tenancy

Notice that we pass in the "public" tenantId to the function call above. This is the default tenantID and will return the user with the given email that belongs to the public tenant. You can provide a different tenantID if required.

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.

Getting the user's third party provider information and access token

If the user used a third party provider to login, you can access their info via SuperTokens as shown below. You can then save the OAuthTokens in your own db or in SuperTokens (using the user metadata recipe) and use them to fetch / change info about the logged in user from the third party provider
