JavaScript SDK quick start

This guide describes how to quickly integrate Detection and Response services into your web application to get started. This includes both the client-side integration, as well as the backend API integration required to complete the flow.

Before you start

Before you start integrating the SDK, you need to ensure effective communication with Transmit's assets. This includes:

• Enabling Transmit's IPs and URLs on your network
• Extending the Content-Security-Policy header (if you have enabled Content Security Policy (MDN) on your web server)

See Enable communication with Transmit APIs for additional information.

Step 1: Get client credentials

Client credentials are used to identify your app and generate access tokens for authorizing Transmit requests. To obtain them, you'll need to create an application in the Admin Portal (if you don’t have one yet).

1. From Applications , click Add application .
2. Add the friendly application name to display in the Admin Portal.
3. Add a client display name, and your website URL as a redirect URI (e.g., https://your-domain.com ).

   Note

   These fields are required for all Transmit apps, but won’t be used for Detection and Response.

4. Click Add to create your application. This will automatically generate your client credentials.

Step 2: Load SDK

Start monitoring your end-user risk levels by loading the SDK. To do this, add the code below to your front-end web application by including the following HTML script tag in all relevant pages. The [CLIENT_ID] should be replaced with your client ID from step 1.

<script src="https://platform-websdk.transmitsecurity.io/platform-websdk/latest/ts-platform-websdk.js" defer="true" id="ts-platform-script"></script>

You also need to initialize and configure the SDK by adding the following HTML script tag in all relevant pages:

<script>
  document.getElementById("ts-platform-script").addEventListener("load", function() {
    window.tsPlatform.initialize({ clientId: "[CLIENT_ID]" });
  });
</script>

Step 3: Set user

A user identifier must be reported to Transmit Security after you've fully authenticated the user (including, for example, any required 2FA that was done). This will set the user for all subsequent events in the browser session.

To do this, add the JS code below after your application has authenticated a user (or after SDK initialization if you already have the user context of the authenticated user when loading the page). The [USER_ID] is an opaque identifier for the user in your system.

window.tsPlatform.drs.setAuthenticatedUser('[USER_ID]');

Step 4: Report actions

To obtain risk recommendations for sensitive actions, your application should report these actions using the SDK. To do this, add the JS code below to relevant user interactions (such as the Login button click event handler). The [ACTION_TYPE] can be either login, register, transaction, password_reset, logout, checkout, account_details_change, account_auth_change, withdraw or credits_change.

window.tsPlatform.drs.triggerActionEvent("[ACTION_TYPE]").then((actionResponse) => {
  let actionToken = actionResponse.actionToken;
  // Add code here to send the action and the received actionToken to your backend
});

Step 5: Fetch recommendation

You can fetch recommendations for the reported action using the Recommendation API. This is the same API that's also used for mobile integrations.

Transmit Security APIs are authorized using an OAuth access token so you'll need to fetch a token using your client credentials (from step 1). The token should target the following resource: https://risk.identity.security. To do this, send the following request:

  const { access_token } = await fetch(
    `https://api.transmitsecurity.io/oidc/token`,
    {
      method: 'POST',
      headers: {
        'Content-Type': 'application/x-www-form-urlencoded'
      }
      body: new URLSearchParams({
        grant_type: client_credentials,
        client_id: [CLIENT_ID],
        client_secret: [CLIENT_SECRET],
        resource: 'https://risk.identity.security'
      })
    }
  );

From your backend, invoke the Recommendation API by sending a request like the one below. The [ACCESS_TOKEN] is the authorization token you obtained using your client credentials and [ACTION_TOKEN] is the actionToken received from the SDK in step 4.

const query = new URLSearchParams({
  action_token: '[ACTION_TOKEN]',
}).toString();

const resp = await fetch(
  `https://api.transmitsecurity.io/risk/v1/recommendation?${query}`,
  {
    method: 'GET',
    headers: {
      Authorization: 'Bearer [ACCESS_TOKEN]',
    },
  }
);

Step 6: Clear user

After the user logs out or the user session expires, you should clear the set user so they are not associated with future actions. To clear the user, call the clearUser() method:

window.tsPlatform.drs.clearUser();
