Overview

Session Persistence is the Web Widget’s ability to continue the session on a different page in the same domain where the widget is embedded. This functionality currently only works for pages loaded within the same tab of the browser.

In order to get the session persistence functionality, you would have to update the API keys generated for the project to include the session persistence toggle.

Navigation using Content Cards

There are several ways to implement navigation if you have a persisted widget across multiple pages. As a conversation writer, you can use the Internal Links Card(s) to present links to the desired pages within your domain to the user. The user can then click on the card to navigate to the desired page. The page would reload to the new page and the Digital Person would resume the session from there.

Example Code for navigation using Internal link Card

Navigation using links on the webpage

Clicking on a link within a webpage can redirect a user to another page, in which case widget embed code must be present on the possible navigable pages to make sure session persistence is maintained.

Custom DP Response on Page Load

Digital People can be trained to introduce a page with custom responses when users are redirected to new pages. When a new page is loaded, we send a PageMetadata as the input to the NLP. We also set pageUrl as a variable that contains the URL of the loaded page. For training the intent, use PageMetadata as the training phrase. In order to respond differently to various URLs, you will need to do a conditional response based on the pageUrl. More specific examples are provided below.

These examples aim to keep a welcome sentence for the user when they first connect and to not repeat unnecessary phrases or fallback if the URL is not set up to be recognized in the corpus.

Watson (Classic)

1. In a Watson skill, set up intent with Page Metadata as a user example:

   

2. Moving to Dialog in the left-hand menu, modify Welcome to also trigger if the page metadata intent is triggered.

   

3. Add a child node underneath welcome that recognizes the page loaded intent. 

   

4. Add a child node underneath the one you just created (in the screenshot above, it’s called Navigation). Using the $pageUrl that has been sent from the widget (no need to create this anywhere else in Watson), we can change what the assistant recognizes to change the response provided like below:

   

5. At the bottom of this node under “Then assistant should” change it to Jump To and select Navigation (If assistant recognizes (condition)).

   

6. Repeat steps 4 and 5 for as many URLs as you would like your corpus to recognize. Each should be a child node of Navigation like this:

   

DialogFlow CX

1. Configure Welcome intent as described in the section Configuring the welcome event.

2. On the left side add a new page called “Determine Page”.

   

3. Set “Transition” to “Determine Page” at “Welcome Event handler”.

   

4. Click ““Determine Page” in the flow diagram to expand it.

5. In the “Determine Page” Click the + button next to Route.

6. Click the Intent dropdown and select +new Intent.

7. Choose a display name (in this case “Page Metadata”) and add “PAGE_METADATA” as the training phase.

   

8. Save the intent.

9. Add a “Condition” for if the $session.params.pageUrl = '[page url expected]'. This can be Or, And or a custom expression depending on if you’d like other conditions.

10. Add expected “Fulfillment” of what you would like the DP to say and save the Route.

    

11. Change the Transition Page to the same one “Determine page” so that it loops.

    

12. Add similar Routes in “Determine Page” for different page URLs, or you can create a Route group and include all “Page Metadata” intent within one route group.
