Specify the User for Skin Consultant App by providing an external user ID

This page explains how you can pass your external user IDs to the Skin Consultant App and link them with Haut.AI's user names in the Skin Consultant App

Haut.AI has a concept of subject to store and process data separately for different real users. You can read more about subjects here: Subjects

Option 1: Automatic User Detection by Haut.AI

By default, the Skin Consultant App identifies the user automatically by device + browser fingerprint.

• New User: When a new fingerprint is identified, a new subject will be created. The subject will be assigned an automatically generated internal ID -subject_ID;

• Existing User: When the same device + browser fingerprint is used to access the Skin Consultant App again (read: same user returned to the app), the Skin Consultant App will automatically identify the already existing subject.

When is this option applicable?

• If your product (website or mobile application) has no authentication feature.

• If your product has an authentication feature, but your users can access the Skin Consultant App without it (for example, the Skin Consultant App is a part of the lead generation funnel, leading to the registration page)

Option 2: Define User via External User ID passing

You can optionally pass your external user IDs to the Skin Consultant App's name parameter.

• New User: When you pass an external user ID as a name that does not yet exist in SaaS, a new subject will be created. The subject will be assigned an automatically generated internal ID -subject_ID, — and a name equal to your external user ID;

• Existing User: When you pass an external user ID as a name that already exists in the SaaS, the Skin Consultant App will use the existing subject.

When it is applicable

• If your product has an authentication feature, and users are assigned user IDs, and the Skin Consultant App experience starts after your user logins to your system.

Benefits

By linking your external user IDs with Haut.AI's name parameter, you will:

• Enable better tracking of users, especially in multi-tenant applications.

• Enhance the ability to better segment and analyze user behavior (for example, compare the behavior of users who did and did not use Skin Consultant App).

Create personalized links by adding an External User ID

Each your Skin Consultant App has a unique URL that allows to open it as a separate webpage or integrate it (see Integrate Skin Consultant App to your e-Commerce Website). You can find link here: Previewing your Skin Consultant app.

The URL has the following format:

https://saas.haut.ai/b2c/first-entrance?app_id=<app_id>&company_id=<company_id>&utm_campaign=<campaign_name>&company_cid=<company_code>

What does each parameter in URL mean?

• app_id: The unique identifier for your Skin Consultant App. Never change this parameter.

• company_id: The identifier of your company within Haut.AI SaaS. Never change this parameter.

• company_cid: A client identification number of your company. Never change this parameter.

• utm_campaign: Used for tracking the campaign that led the user to the app. Never change this parameter.

&name=<external_user_id>

external_user_id must be a string (simple text) with a max length of 512 symbols

Example

Let's say your user has a user ID in your system as User123. When correctly implemented, your URL for your Skin Consultant App should look like this:

https://saas.haut.ai/b2c/first-entrance?app_id=<app_id>&company_id=<company_id>&utm_campaign=<campaign_name>&company_cid=<company_code>&name=User123

Recommendations for Implementation (for Developers)

• Your frontend application should be configured to inject parameter name to the URL in the iframe when the user accesses the application. Typically, this is done in the app's initialization code.

• Validate the incoming query parameters to prevent potential security vulnerabilities, such as injection attacks.
