HESK Add-ons & Plugins
Premium, supported drop-in add-ons that extend HESK Help Desk — a REST API, Slack & Discord webhooks, and built-in anti-spam. No core hacks, no monthly fees. Whether you call them HESK add-ons, plugins, mods or extensions, they install in minutes and keep working after you upgrade HESK.
Extending HESK with add-ons & plugins
HESK is a free, lightweight help desk trusted by thousands of teams — but it ships lean and has no official plugin marketplace. To add features you reach for add-ons: extra PHP that plugs into your existing HESK install.
There are two kinds. Free community mods — like the popular “Mods for HESK” project and the add-ons shared on help-desk forums — typically patch HESK's core files by hand. They're useful, but a HESK upgrade can overwrite them and there's no support line when something breaks.
HeskAPI add-ons are different. Each one is a self-contained drop-in that never edits HESK core, so it survives upgrades. They're security-reviewed, licensed, and backed by a year of updates and support — the premium, supported end of the HESK plugin ecosystem.
The HESK add-on catalog
Drop-in HESK add-ons you can install today — plus what's coming next.
HeskAPI — REST API
The flagship HESK add-on: a secure REST API for tickets, replies and attachments, with double opt-in email verification and a spam queue to kill bot tickets.
- 6 endpoints — list, search, create, update, reply, close
- API-key auth + per-IP rate limiting
- Anti-spam email verification & real submitter IP
HESK Discord Webhook
Post a rich Discord embed to any channel the moment a new HESK ticket is created. Standalone — works with or without the API.
- Priority-coloured embeds with a direct ticket link
- Category & priority filters
- Cron-driven, first-run watermark (no old-ticket flood)
HESK Slack Webhook
Send a formatted Slack message to any channel or DM whenever a new HESK ticket arrives. Colour-coded by priority.
- Slack attachment format, priority sidebar
- Clickable ticket title → HESK admin
- Category & priority filters, custom bot icon
API + Webhook Bundle
The REST API plus your choice of the Discord or Slack webhook, bundled at a discount — the full HESK add-on stack.
- Everything in HeskAPI
- One webhook of your choice included
- Save $9 vs buying separately
HESK Toolkit
Coming soonA growing suite of HESK automation add-ons — no API required. On the roadmap: auto-close stale tickets, auto-assignment / routing, SLA tracking & escalation, business-hours auto-reply, and customer satisfaction (CSAT) surveys — the features stock HESK is missing.
Get notifiedHESK add-on or HESK mod — what's the difference?
The words are used interchangeably in the HESK community. What actually matters is how the code installs and whether it's supported.
| Free community mods | HeskAPI add-ons | |
|---|---|---|
| Installs without editing HESK core | Often patches core files | Yes — pure drop-in |
| Survives a HESK upgrade | May be overwritten | Yes |
| Security-reviewed | Varies by author | Yes |
| Updates & support | Community / best-effort | 1 year included |
| Licensed & guaranteed | No | Yes |
| Cost | Free | One-time, from $19 |
Prefer a free HESK mod? Great — they're a big part of the ecosystem. When you need something supported and upgrade-safe, that's what HeskAPI add-ons are for.
How to install a HESK add-on
Download your add-on
After purchase you get a per-domain, licensed ZIP — the REST API module, a webhook script, or the bundle.
Drop it into your HESK directory
Upload the files alongside your existing HESK install. No core files are edited and nothing is overwritten — the add-on reads HESK's own config and database.
Configure & go
Set your options in the built-in admin panel (API) or the constants at the top of the script (webhooks), add a cron line where needed, and you're live.
No framework, no composer, no core hacks — see the full docs.
