Auth0 JWT

Set up an Auth0 action to get a Tinybird JWT token as part of the post-login Auth0 trigger.

Prerequisites

1. An Auth0 account and tenant. Sign up for free.
2. A Tinybird account and workspace. Sign up for free.

Add the Auth0 Action

• Go to Auth0 > Actions > Triggers > post-login
• Add a new custom action:

const jwt = require("jsonwebtoken");

exports.onExecutePostLogin = async (event, api) => {
  if (!event.secrets.TINYBIRD_ADMIN_TOKEN) {
    console.log("Tinybird Admin Token is missing. Create a secret with name TINYBIRD_ADMIN_TOKEN.");
    return;
  }

  if (!event.configuration.TINYBIRD_WORKSPACE_ID) {
    console.log(
      "Tinybird Workspace ID is missing. Create a configuration variable with name TINYBIRD_WORKSPACE_ID."
    );
    return;
  }

  if (!event.configuration.TINYBIRD_PIPE_NAMES) {
    console.log(
      "Tinybird Pipe Names is missing. Create a configuration variable with name TINYBIRD_PIPE_NAMES."
    );
    return;
  }

  const scopes = event.configuration.TINYBIRD_PIPE_NAMES.split(",").map((pipeName) => ({
    type: "PIPES:READ",
    resource: pipeName,
  }));

  const payload = {
    workspace_id: event.configuration.TINYBIRD_WORKSPACE_ID,
    name: `tinybird_jwt_${event.user.id}`,
    scopes,
  };

  const options = {
    expiresIn: "7d",
  };

  const secret = event.secrets.TINYBIRD_ADMIN_TOKEN;
  const token = jwt.sign(payload, secret, options);
  api.user.setAppMetadata("tinybirdJWT", token);

  if (event.authorization) {
    api.idToken.setCustomClaim("https://app.tinybird.co", token);
  }

  console.log(`Tinybird JWT token set for user`);
};

• Configure the action with the required secrets and configuration variables
• Save the action
• Modify the post-logintrigger to use the action

How to use the JWT token

The JWT token will be set in the id token with name https://app.tinybird.co as part of the post-login Auth0 workflow.

const user = await auth0Client.getUser();
const tinybirdJWT = user["https://app.tinybird.co"];

// Use the token to fetch data from Tinybird
const response = await fetch("https://api.tinybird.co/v0/pipes/your_pipe.json", {
  headers: {
    Authorization: `Bearer ${tinybirdJWT}`
  }
});

const data = await response.json();
console.log(data);
