TokenLink SSO Login for Zendesk allows WordPress site administrators to provide seamless, secure single sign-on (SSO) access to Zendesk using JWT (JSON Web Tokens) authentication.
This plugin uses the official Firebase PHP-JWT library (BSD 3-Clause licensed, included and updated for WordPress compliance).
Setup takes less than five minutes using standard WordPress shortcodes — no third-party dependencies, no tracking, no bloat.

Request Form for Zendesk

It is actually a pretty-well build plugin that covers 80% of all zendesk-related issues. Been looking initially at Gravity Forms + Zendesk (by crmperks) combination and this one is much better coded. Also, custom fields are supported and that is a premium feature in competing plugins. Well done!

One thing I'd like to add here is support for Zendesk Tags. Sending tags with forms would make it so much easier to handle complex business logic.

Great plugin

Add a Zendesk Support Form directly to your WordPress site.
