Authorize using a user token

const { AuthressClient } = require('@authress/sdk');

// on api route
[route('/resources/<resourceId>')]
async function getResource(resourceId) {
  // Get the user token and pass it to authress
  const authorizationToken = request.headers.get('authorization');

  // What is my authressApiUrl? => API Host: https://authress.io/app/#/api?route=overview
  const authressClient = new AuthressClient({ authressApiUrl: 'https://auth.yourdomain.com' }, () => authorizationToken);

  // Check Authress to authorize the user
  try {
    await authressClient.userPermissions.authorizeUser(userId, `resources/${resourceId}`, 'READ');
  } catch (error) {
    // Will throw except if the user is not authorized to read the resource
    if (error.code === 'UnauthorizedError') {
      return 404;
    }
    throw error;
  }

  // On success, continue with the route code to load resource and return it
  return { resource: {}, statusCode: 200 };
}

Authorize with a service client

const { AuthressClient } = require('@authress/sdk');

// create an instance of the API class during service initialization
// Replace DOMAIN with the Authress domain for your account

// Create a service client in the Authress management portal and past the access token here
// This will generate a token automatically instead of passing the user token to the api
const accessToken = 'eyJrZXlJ....';
const authressClient = new AuthressClient({ authressApiUrl: 'https://auth.yourdomain.com' }, accessToken);

// on api route
[route('/resources/<resourceId>')]
async function getResource(resourceId) {
  // Check Authress to authorize the user
  try {
    await authressClient.userPermissions.authorizeUser(userId, `resources/${resourceId}`, 'READ');
  } catch (error) {
    // Will throw except if the user is not authorized to read the resource
    if (error.code === 'UnauthorizedError') {
      return 404;
    }
    throw error;
  }

  // On success, continue with the route code to load resource and return it
  return { resource: {}, statusCode: 200 };
}

Creating resources

When a user creates a resource in your application, we want to ensure that they get access own that resource.

You may receive User does not have sufficient access to grant permissions to resources as an error along with the status code 403. This means that the service client or user jwt does not have access to create the access record. If using a service client, go to the Authress portal and create a one time record which grants the service client Authress:Owner to Resources/ so that it can manage access records for these types of resources.

await authressClient.accessRecords.createRecord({
  name: `Access To New Resource ${NewResourceId}`,
  users: [{ userId: requestUserId }],
  statements: [{
    resources: [{ resourceUri: `Resources/${NewResourceId}` }],
    // Owner by default gives full control over this new resource, including the ability to grant others access as well.
    roles: ['Authress:Owner']
  }]
});

Verifying a token using the token verifier

const { AuthressClient } = require('@authress/sdk');
const cookieManager = require('cookie');

const authressClient = new AuthressClient({ authressApiUrl: 'https://auth.yourdomain.com' });

try {
  // Grab authorization cookie from the request, the best way to do this will be framework specific.
  const cookies = cookieManager.parse(request.headers.cookie || '');
  const userToken = cookies.authorization || request.headers.Authorization.split(' ')[1];
  // What should my url be? => https://authress.io/app/#/setup?focus=domain
  const userIdentity = await authressClient.verifyToken(userToken);
} catch (error) {
  console.log('User is unauthorized', error);
  return { statusCode: 401 };
}

Make direct API requests

Authress supports extended functionality via the REST api, in specific cases it helps to make these direct calls. Each API call requires a URL and an access token. In the case you want use the access token for the user, directly pass it as the bearer in the Authorization header:

const response = await client.get(url, { 'Authorization': `Bearer: ${userAccessToken}` });

In the case you want to make a request using the service client's secret key, use the serviceClientTokenProvider you've already configured:

// Standard library configuration:
const { AuthressClient, ServiceClientTokenProvider } = require('@authress/sdk');
const accessToken = 'eyJrZXlJ....';
const serviceClientTokenProvider = new ServiceClientTokenProvider(accessToken);
const authressClient = new AuthressClient({ authressApiUrl: 'https://auth.yourdomain.com' }, serviceClientTokenProvider);

// Get a temporary token and use it:
const temporaryServiceClientAccessToken = await serviceClientTokenProvider.getToken();
const response = await client.get(url, { 'Authorization': `Bearer: ${temporaryServiceClientAccessToken}` });

Paginating through a collection resource

Some of the resources in the API are paginated. These resources contain a pagination.next.cursor property when there is a next page. The cursor can be passed to query to fetch the next page. Here's an example usage:

const { AuthressClient } = require('@authress/sdk');

// on api route
async function (resourceId) {
  // Get the user token and pass it to authress
  const authorizationToken = request.headers.get('authorization');
  const authressClient = new AuthressClient({ authressApiUrl: 'https://auth.yourdomain.com' }, () => authorizationToken);

  // Get the users resources
  const response = await authressClient.userPermissions.getUserResources(userId, `resources/*`, 10, null, 'READ');
  for (const resource of response.data.resources) {
    // Iterate on resource
  }

  // Get the next page:
  const nextPageResponse = await authressClient.userPermissions.getUserResources(userId, `resources/*`, 10, response.data.pagination.next.cursor, 'READ');
  for (const resource of nextPageResponse.data.resources) {
    // Iterate on resource
  }

  // Get all the next pages:
  let cursor = response.data.pagination?.next?.cursor;
  while (cursor) {
    const response = await authressClient.userPermissions.getUserResources(userId, `resources/*`, 10, cursor, 'READ');
    cursor = response.data.pagination?.next?.cursor;
    for (const resource of response.data.resources) {
      // Iterate on resource
    }
  }
}
