Which UI do you use?

Custom UI

Pre built UI

Fetching the user's tenant ID

Multi Tenancy

This feature is only relevant if you are using the multi tenancy feature.

The session's access token payload contains the tenant ID of the tenant that the user logged in via. This can be found in the tId claim of the access token.

Fetching on the backend

You can use the getTenantId function from the session object post session verification:

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

Express

import express from "express";
import { verifySession } from "supertokens-node/recipe/session/framework/express";
import { SessionRequest } from "supertokens-node/framework/express";

let app = express();

app.post("/like-comment", verifySession(), (req: SessionRequest, res) => {
    let tenantId = req.session!.getTenantId();
    //....
});

Hapi

import Hapi from "@hapi/hapi";
import { verifySession } from "supertokens-node/recipe/session/framework/hapi";
import { SessionRequest } from "supertokens-node/framework/hapi";

let server = Hapi.server({ port: 8000 });

server.route({
    path: "/like-comment",
    method: "post",
    options: {
        pre: [
            {
                method: verifySession()
            },
        ],
    },
    handler: async (req: SessionRequest, res) => {
        let tenantId = req.session!.getTenantId();
        //...
    }
})

Fastify

import Fastify from "fastify";
import { verifySession } from "supertokens-node/recipe/session/framework/fastify";
import { SessionRequest } from "supertokens-node/framework/fastify";

let fastify = Fastify();

fastify.post("/like-comment", {
    preHandler: verifySession(),
}, (req: SessionRequest, res) => {
    let tenantId = req.session!.getTenantId();
    //....
});

Koa

import { verifySession } from "supertokens-node/recipe/session/framework/awsLambda";
import { SessionEventV2 } from "supertokens-node/framework/awsLambda";

async function likeComment(awsEvent: SessionEventV2) {
    let tenantId = awsEvent.session!.getTenantId();
    //....
};

exports.handler = verifySession(likeComment);

Loopback

import KoaRouter from "koa-router";
import { verifySession } from "supertokens-node/recipe/session/framework/koa";
import { SessionContext } from "supertokens-node/framework/koa";

let router = new KoaRouter();

router.post("/like-comment", verifySession(), (ctx: SessionContext, next) => {
    let tenantId = ctx.session!.getTenantId();
    //....
});

AWS Lambda / Netlify

import { inject, intercept } from "@loopback/core";
import { RestBindings, MiddlewareContext, post, response } from "@loopback/rest";
import { verifySession } from "supertokens-node/recipe/session/framework/loopback";
import { SessionContext } from "supertokens-node/framework/loopback";

class LikeComment {
    constructor(@inject(RestBindings.Http.CONTEXT) private ctx: MiddlewareContext) { }
    @post("/like-comment")
    @intercept(verifySession())
    @response(200)
    handler() {
        let tenantId = (this.ctx as SessionContext).session!.getTenantId();
        //....
    }
}

Next.js

import { superTokensNextWrapper } from 'supertokens-node/nextjs'
import { verifySession } from "supertokens-node/recipe/session/framework/express";
import { SessionRequest } from "supertokens-node/framework/express";

export default async function likeComment(req: SessionRequest, res: any) {
    await superTokensNextWrapper(
        async (next) => {
            await verifySession()(req, res, next);
        },
        req,
        res
    )

    let tenantId = req.session!.getTenantId();
    //....
}

NestJS

import { Controller, Post, UseGuards, Session } from "@nestjs/common";
import { SessionContainer } from "supertokens-node/recipe/session";
import { AuthGuard } from './auth/auth.guard';

@Controller()
export class ExampleController {
  @Post('example')
  @UseGuards(new AuthGuard()) // For more information about this guard please read our NestJS guide.
  async postExample(@Session() session: SessionContainer): Promise<boolean> {
    let tenantId = session.getTenantId();

    //....
    return true;
  }
}

note

If you are not using our backend SDK and are doing JWT verification yourself, you can fetcht the tenant ID from the JWT by reading the tId claim.

Fetching on the frontend

You can read the tenant ID on the frontend by readin the tId claim from the access token payload.
