Which UI do you use?

Custom UI

Pre built UI

Manually generating a link

You can use our backend SDK to generate magic links as shown below:

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

import ThirdPartyPasswordless from "supertokens-node/recipe/thirdpartypasswordless";

async function createMagicLink(email: string) {
    const magicLink = await ThirdPartyPasswordless.createMagicLink({email, tenantId: "public"});

    console.log(magicLink);
}

Python

import (
    "fmt"
    
    "github.com/supertokens/supertokens-golang/recipe/thirdpartypasswordless"
)

func main() {
    email := "..."

    tenantId := "public"
    magicLink, err := thirdpartypasswordless.CreateMagicLinkByEmail(tenantId, email)
    if err != nil {
        // handle error
    }

    fmt.Println(magicLink)
}

Other Frameworks

Asyncio

from supertokens_python.recipe.thirdpartypasswordless.asyncio import create_magic_link

async def create_link(email: str):
    magic_link = await create_magic_link("public", email, phone_number=None)

    print(magic_link)

Syncio

from supertokens_python.recipe.thirdpartypasswordless.syncio import create_magic_link

def create_link(email: str):
    magic_link = create_magic_link("public", email, phone_number=None)

    print(magic_link)

Multi Tenancy

Notice that we pass in the "public" tenantId to the function call above - which is the default tenantId.

If you are using our multi tenancy feature, you can pass in another tenantId which will be embedded in the link by SuperTokens. This will ensure that when the user clicks on the link and signs up, they sign up to the tenant you want to give them access to.

Note that the generated link will use the configured websiteDomain from the appInfo object (in supertokens.init), however, you can change the domain of the generated link to match that of the tenant ID.
