Getting Started

$3

This library supports the following tooling versions:

- Node.js: ^20.19.0 || ^22.12.0 || ^24.0.0

$3

Using npm in your project directory run the following command:

``bash
npm install auth0
`

$3

#### Authentication API Client

This client can be used to access Auth0's Authentication API.

`js
import { AuthenticationClient } from "auth0";

const auth0 = new AuthenticationClient({
domain: "{YOUR_TENANT_AND REGION}.auth0.com",
clientId: "{YOUR_CLIENT_ID}",
clientSecret: "{OPTIONAL_CLIENT_SECRET}",
});
`

#### Management API Client

The Auth0 Management API is meant to be used by back-end servers or trusted parties performing administrative tasks. Generally speaking, anything that can be done through the Auth0 dashboard (and more) can also be done through this API.

Initialize your client class with a domain and token:

`js
import { ManagementClient } from "auth0";

const management = new ManagementClient({
domain: "{YOUR_TENANT_AND REGION}.auth0.com",
token: "{YOUR_API_V2_TOKEN}",
});
`

Or use client credentials:

`js
import { ManagementClient } from "auth0";

const management = new ManagementClient({
domain: "{YOUR_TENANT_AND REGION}.auth0.com",
clientId: "{YOUR_CLIENT_ID}",
clientSecret: "{YOUR_CLIENT_SECRET}",
withCustomDomainHeader: "auth.example.com", // Optional: Auto-applies to whitelisted endpoints
});
`

#### UserInfo API Client

This client can be used to retrieve user profile information.

`js
import { UserInfoClient } from "auth0";

const userInfo = new UserInfoClient({
domain: "{YOUR_TENANT_AND REGION}.auth0.com",
});

// Get user info with an access token
const userProfile = await userInfo.getUserInfo(accessToken);
`

Legacy Usage

If you are migrating from the legacy node-auth0 package (v4.x) or need to maintain compatibility with legacy code, you can use the legacy export which provides the node-auth0 v4.x API interface.

$3

The legacy version (node-auth0 v4.x) is available through the /legacy export path:

`js
// Import the legacy version (node-auth0 v4.x API)
import { ManagementClient, AuthenticationClient } from "auth0/legacy";

// Or using CommonJS
const { ManagementClient, AuthenticationClient } = require("auth0/legacy");
`

$3

The legacy API uses the node-auth0 v4.x configuration format and method signatures, which are different from the current v5 API:

#### Legacy Management Client

`js
import { ManagementClient } from "auth0/legacy";

const management = new ManagementClient({
domain: "{YOUR_TENANT_AND REGION}.auth0.com",
clientId: "{YOUR_CLIENT_ID}",
clientSecret: "{YOUR_CLIENT_SECRET}",
scope: "read:users update:users",
});

// Legacy API methods use promise-based patterns (node-auth0 v4.x style)
management.users
.getAll()
.then((users) => console.log(users))
.catch((err) => console.error(err));

// Or with async/await
try {
const users = await management.users.getAll();
console.log(users);
} catch (err) {
console.error(err);
}
`

#### Legacy Authentication Client

`js
import { AuthenticationClient } from "auth0/legacy";

const auth0 = new AuthenticationClient({
domain: "{YOUR_TENANT_AND REGION}.auth0.com",
clientId: "{YOUR_CLIENT_ID}",
clientSecret: "{YOUR_CLIENT_SECRET}",
});

// Legacy authentication methods (node-auth0 v4.x style)
auth0.oauth
.passwordGrant({
username: "user@example.com",
password: "password",
audience: "https://api.example.com",
})
.then((userData) => {
console.log(userData);
})
.catch((err) => {
console.error("Authentication error:", err);
});

// Or with async/await
try {
const userData = await auth0.oauth.passwordGrant({
username: "user@example.com",
password: "password",
audience: "https://api.example.com",
});
console.log(userData);
} catch (err) {
console.error("Authentication error:", err);
}
`

$3

When migrating from node-auth0 v4.x to the current v5 SDK, note the following key differences:

1. Method Names: Many method names have changed to be more descriptive
2. Type Safety: Enhanced TypeScript support with better type definitions
3. Error Handling: Unified error handling with specific error types
4. Configuration: Simplified configuration options

#### Example Migration

Legacy (node-auth0 v4.x) code:

`js
const { ManagementClient } = require("auth0/legacy");

const management = new ManagementClient({
domain: "your-tenant.auth0.com",
clientId: "YOUR_CLIENT_ID",
clientSecret: "YOUR_CLIENT_SECRET",
scope: "read:users",
});

// With promises
management.users
.getAll({ search_engine: "v3" })
.then((users) => {
console.log(users);
})
.catch((err) => {
console.error(err);
});

// Or with async/await
try {
const users = await management.users.getAll({ search_engine: "v3" });
console.log(users);
} catch (err) {
console.error(err);
}
`

v5 equivalent:

`js
import { ManagementClient } from "auth0";

const management = new ManagementClient({
domain: "your-tenant.auth0.com",
clientId: "YOUR_CLIENT_ID",
clientSecret: "YOUR_CLIENT_SECRET",
});

// With promises
management.users
.list({
searchEngine: "v3",
})
.then((users) => {
console.log(users);
})
.catch((error) => {
console.error(error);
});

// Or with async/await
try {
const users = await management.users.list({
searchEngine: "v3",
});
console.log(users);
} catch (error) {
console.error(error);
}
`

Request and Response Types

The SDK exports all request and response types as TypeScript interfaces. You can import them directly:

`typescript
import { ManagementClient, Management, ManagementError } from "auth0";

const client = new ManagementClient({
domain: "your-tenant.auth0.com",
token: "YOUR_TOKEN",
});

// Use the request type
const listParams: Management.ListActionsRequestParameters = {
triggerId: "post-login",
actionName: "my-action",
};

const actions = await client.actions.list(listParams);
`

Exception Handling

When the API returns a non-success status code (4xx or 5xx response), a subclass of the following error
will be thrown.

`typescript
import { ManagementError } from "auth0";

try {
await client.actions.create({
name: "my-action",
supported_triggers: [{ id: "post-login" }],
code: "exports.onExecutePostLogin = async (event, api) => { console.log('Hello World'); };",
});
} catch (err) {
if (err instanceof ManagementError) {
console.log(err.statusCode);
console.log(err.message);
console.log(err.body);
console.log(err.rawResponse);
}
}
`

Pagination

Some list endpoints are paginated. You can iterate through pages using default values:

`typescript
import { ManagementClient } from "auth0";

const client = new ManagementClient({
domain: "your-tenant.auth0.com",
token: "YOUR_TOKEN",
});

// Using default pagination (page size defaults vary by endpoint)
let page = await client.actions.list();
for (const item of page.data) {
console.log(item);
}

while (page.hasNextPage()) {
page = await page.getNextPage();
for (const item of page.data) {
console.log(item);
}
}
`

Or you can explicitly control pagination using page and per_page parameters:

`typescript
// Offset-based pagination (most endpoints)
let page = await client.actions.list({
page: 0, // Page number (0-indexed)
per_page: 25, // Number of items per page
});

for (const item of page.data) {
console.log(item);
}

while (page.hasNextPage()) {
page = await page.getNextPage();
for (const item of page.data) {
console.log(item);
}
}
`

Some endpoints use checkpoint pagination with from and take parameters:

`typescript
// Checkpoint-based pagination (e.g., connections, organizations)
let page = await client.connections.list({
take: 50, // Number of items per page
});

for (const item of page.data) {
console.log(item);
}

while (page.hasNextPage()) {
page = await page.getNextPage();
for (const item of page.data) {
console.log(item);
}
}
`

Advanced

$3

If you would like to send additional headers as part of the request, use the headers request option.

`typescript
const response = await client.actions.create(
{
name: "my-action",
supported_triggers: [{ id: "post-login" }],
},
{
headers: {
"X-Custom-Header": "custom value",
},
},
);
`

$3

The SDK provides convenient helper functions for common request configuration patterns:

`typescript
import { ManagementClient, CustomDomainHeader, withTimeout, withRetries, withHeaders, withAbortSignal } from "auth0";

const client = new ManagementClient({
domain: "your-tenant.auth0.com",
token: "YOUR_TOKEN",
});

// Example 1: Use custom domain header for specific requests
const reqOptions = {
...CustomDomainHeader("auth.example.com"),
timeoutInSeconds: 30,
};
await client.actions.list({}, reqOptions);

// Example 2: Combine multiple options
const reqOptions = {
...withTimeout(30),
...withRetries(3),
...withHeaders({
"X-Request-ID": crypto.randomUUID(),
"X-Operation-Source": "admin-dashboard",
}),
};
await client.actions.list({}, reqOptions);

// Example 3: For automatic custom domain header on whitelisted endpoints
const client = new ManagementClient({
domain: "your-tenant.auth0.com",
token: "YOUR_TOKEN",
withCustomDomainHeader: "auth.example.com", // Auto-applies to whitelisted endpoints
});

// Example 4: Request cancellation
const controller = new AbortController();
const reqOptions = {
...withAbortSignal(controller.signal),
...withTimeout(30),
};
const promise = client.actions.list({}, reqOptions);

// Cancel after 10 seconds
setTimeout(() => controller.abort(), 10000);
`

Available helper functions:

- CustomDomainHeader(domain) - Configure custom domain header for specific requests
- withTimeout(seconds) - Set request timeout
- withRetries(count) - Configure retry attempts
- withHeaders(headers) - Add custom headers
- withAbortSignal(signal) - Enable request cancellation

To apply the custom domain header globally across your application, use the withCustomDomainHeader option when initializing the ManagementClient. This will automatically inject the header for all whitelisted endpoints.

$3

The SDK is instrumented with automatic retries with exponential backoff. A request will be retried as long
as the request is deemed retryable and the number of retry attempts has not grown larger than the configured
retry limit (default: 2).

A request is deemed retryable when any of the following HTTP status codes is returned:

- 408 (Timeout)
- 429 (Too Many Requests)
- 5XX (Internal Server Errors)

Use the maxRetries request option to configure this behavior.

`typescript
const response = await client.actions.create(
{
name: "my-action",
supported_triggers: [{ id: "post-login" }],
},
{
maxRetries: 0, // override maxRetries at the request level
},
);
`

$3

The SDK defaults to a 60 second timeout. Use the timeoutInSeconds option to configure this behavior.

`typescript
const response = await client.actions.create(
{
name: "my-action",
supported_triggers: [{ id: "post-login" }],
},
{
timeoutInSeconds: 30, // override timeout to 30s
},
);
`

$3

The SDK allows users to abort requests at any point by passing in an abort signal.

`typescript
const controller = new AbortController();
const response = await client.actions.create(
{
name: "my-action",
supported_triggers: [{ id: "post-login" }],
},
{
abortSignal: controller.signal,
},
);
controller.abort(); // aborts the request
`

$3

The SDK supports configurable logging for debugging API requests and responses. By default, logging is silent.

`typescript
import { ManagementClient } from "auth0";

const client = new ManagementClient({
domain: "your-tenant.auth0.com",
clientId: "YOUR_CLIENT_ID",
clientSecret: "YOUR_CLIENT_SECRET",
logging: {
level: "debug", // "debug" | "info" | "warn" | "error"
silent: false, // Set to false to enable logging output
},
});
`

You can also provide a custom logger implementation:

`typescript
import { ManagementClient } from "auth0";

const customLogger = {
debug: (msg, ...args) => myLogger.debug(msg, args),
info: (msg, ...args) => myLogger.info(msg, args),
warn: (msg, ...args) => myLogger.warn(msg, args),
error: (msg, ...args) => myLogger.error(msg, args),
};

const client = new ManagementClient({
domain: "your-tenant.auth0.com",
clientId: "YOUR_CLIENT_ID",
clientSecret: "YOUR_CLIENT_SECRET",
logging: {
level: "info",
logger: customLogger,
silent: false,
},
});
`

$3

The SDK provides access to raw response data, including headers, through the .withRawResponse() method.
The .withRawResponse() method returns a promise that results to an object with a data and a rawResponse property.

`typescript
const { data, rawResponse } = await client.actions
.create({
name: "my-action",
supported_triggers: [{ id: "post-login" }],
})
.withRawResponse();

console.log(data);
console.log(rawResponse.headers);
`

$3

The SDK defaults to node-fetch` but will use the global fetch client if present. The SDK works in the following
runtimes:

- Node.js 20.19.0+, 22.12.0+, 24+
- Vercel
- Cloudflare Workers
- Deno v1.25+
- Bun 1.0+
- React Native
