Userback

The JavaScript SDK lets your own code control Userback beyond what the widget does on its own:

Track users. Use <code>identify()</code> for apps where people log in or switch accounts, or the simpler <code>user_data</code> option if your site is static. See How to Identify Users.

Trigger feedback from your own UI. Open the widget from a custom button instead of the default launcher.

Prefill the form. Pass a name and email into the feedback form ahead of time.

Set the widget's language in code, based on the visitor's language preference.

Attach custom data to submissions, like a product version or a feature flag.

Customize the widget's behavior, including showing or hiding it based on the current page or a user attribute.

Every method above, plus a few more, is documented in full in the <a href="https://docs.userback.io/docs" rel="nofollow noopener noreferrer" target="_blank">JavaScript SDK Method Reference</a>.

For complete method signatures and parameters, see the <a href="https://docs.userback.io" rel="nofollow noopener noreferrer" target="_blank">Developer Docs</a>: the <a href="https://docs.userback.io/docs/javascript-sdk" rel="nofollow noopener noreferrer" target="_blank">JavaScript SDK docs</a> specifically, or <a href="https://docs.userback.io/docs/ios-android" rel="nofollow noopener noreferrer" target="_blank">Mobile SDK docs</a> for iOS/Android/React Native.

The standard Userback widget works out of the box, install the snippet and users can submit feedback right away. The JavaScript SDK adds a layer of control on top of that: who sees the widget, what data gets attached to each piece of feedback, and how it fits into your site.

{appName} in 60 seconds

This prototype demo is aware that you are reading “{title}”. It can point you back to the current article, but a production article-aware Fin contract is still follow-up work.

Prototype article-aware answer

Because you already asked about invitations, this prototype demo can add the follow-up: use the role selector before sending each invite to limit access to the teammate responsibilities.

Prototype role-limiting follow-up

This prototype demo suggests starting with your workspace profile, inviting the team members who need access, and then connecting the integrations you use.

Prototype getting-started answer

In this prototype demo, integrations are configured from workspace settings. Choose the integration, connect the account, and review the enabled permissions.

Prototype integrations answer

In this prototype demo, invite teammates from workspace settings, then choose the access each teammate needs before sending the invitation.

Prototype invite-team answer

This prototype demo does not have a scripted answer for that question yet. Try asking how to invite your team or open a source article. No production Fin API was called.

Prototype answer unavailable

I’ve got this page open. Ask me anything about it and I’ll answer from the docs.
