Chat persistence

When using Voiceflow’s webchat, you control chat persistence (how conversations are remembered) directly within the JavaScript snippet - not through the Voiceflow UI. This allows for more flexibility based on how you want your users' conversations to persist across sessions and browser tabs.

What is chat persistence?

Chat persistence determines whether users will return to an ongoing conversation or start fresh when they reload a page, open a new tab, or come back later. You can choose between different persistence strategies to match your desired user experience.

How to configure persistence

To set your preferred persistence behavior, add the persistence property inside the assistant object in your webchat snippet:

window.voiceflow.chat.load({  
  verify: { projectID: 'your-project-id' },
  url: 'your-runtime-url',
  versionID: 'production',
  assistant: {
    persistence: 'localStorage' // Set your preferred persistence option here
  }
});

Voiceflow supports three persistence options: localStorage, sessionStorage, and memory.
