# Freshdesk Webhooks Freshdesk doesn't have webhook subscriptions. A webhook is an **action** inside an automation rule: **Admin → Workflows → Automations → Ticket Creation** (or **Ticket Updates**) **→ New Rule → Trigger Webhook**. When the rule's conditions match, Freshdesk calls the URL you entered with the method, headers and body you configured. This differs from most providers in three ways: 1. **There is no signature.** Freshdesk doesn't sign the body. There's no HMAC, signing secret or timestamp header, so don't go looking for an `X-Freshdesk-Signature`. It doesn't exist. 2. **You write the payload.** With **Advanced** content you write the JSON body yourself using placeholders such as `{{ticket.id}}`. There are no fixed event type strings, so you have to put an event name in the body yourself. 3. **You choose the request.** The method (GET/POST/PUT/PATCH/DELETE), encoding (JSON, XML or XML-Encoded) and headers are all set in the rule. ## When to Use This Skill - How do I receive Freshdesk webhooks? - How do I verify Freshdesk webhook signatures? (You can't. Send a shared secret in a custom header instead.) - How do I set up "Trigger Webhook" in a Freshdesk automation rule? - What payload does a Freshdesk webhook send? (Whatever you write in the Content section.) - How do I tell a ticket-created webhook from a ticket-updated one? - Why does my Freshdesk webhook keep arriving every 30 minutes? (Retries after a non-2xx response.) ## Verification (core): a shared secret custom header In the Trigger Webhook action, turn on **Add custom headers** and add one line in Freshdesk's `X-Sample-CustomHeader1: VALUE` format: ``` X-Freshdesk-Webhook-Secret: 3f9c0e...a long random hex value... ``` The header name is your choice. Freshdesk treats header names as case-insensitive and sends the value exactly as entered. Check the header in constant time before you parse the body: ```javascript const crypto = require('crypto'); // NOT a Freshdesk signature. This is a secret YOU put in the rule's custom headers. function verifyFreshdeskSecret(headerValue) { const expected = process.env.FRESHDESK_WEBHOOK_SECRET; if (!expected) throw new Error('FRESHDESK_WEBHOOK_SECRET is not set'); // fail closed if (typeof headerValue !== 'string') return false; const a = Buffer.from(headerValue); const b = Buffer.from(expected); // Length check first: timingSafeEqual throws on a length mismatch. return a.length === b.length && crypto.timingSafeEqual(a, b); } // Express lowercases header names: req.get('X-Freshdesk-Webhook-Secret') works too. ``` > **For complete handlers with tests**, see [examples/express/](examples/express/), [examples/nextjs/](examples/nextjs/), [examples/fastapi/](examples/fastapi/). Return `401` for a missing or wrong secret and `500` when the secret isn't configured, so the endpoint never accepts everything by accident. Use a value without spaces, such as `openssl rand -hex 32`. Freshdesk's docs say the trigger won't run if a header has spaces in it. **"Requires authentication"** is a separate toggle in the same action ("provide your API key"). Freshdesk doesn't document what it puts on the wire, so use the custom header described above. See [references/verification.md](references/verification.md). ## The Payload: you define it Choose **Encoding: JSON** and **Content: Advanced**, then write a body with a fixed `event` field for each rule. Here's the body for the Ticket Creation rule: ```json { "event": "ticket_created", "triggered_event": "{{Triggered event}}", "ticket": { "id": "{{ticket.id}}", "subject": "{{ticket.subject}}", "status": "{{ticket.status}}", "priority": "{{ticket.priority}}", "requester_email": "{{ticket.requester.email}}", "url": "{{ticket.url}}" } } ``` The Ticket Updates rule uses the same body with `"event": "ticket_updated"`. - `event` is **this skill's convention**, not a Freshdesk field. Freshdesk defines no event-type strings for webhooks. - `{{Triggered event}}` is "available only in webhooks and returns the name of the event that triggered the rule". Freshdesk doesn't list its possible values, so log it but don't branch on it. - Placeholder values are substituted as text. Treat them as strings and re-fetch the ticket from the Freshdesk API (`GET /api/v2/tickets/{id}`) before you act on anything important. - **Simple Content** sends a list of ticket properties you pick, in a format Freshdesk doesn't document. Use Advanced so the body is predictable. ## Events (this skill's `event` values) | `event` | Rule tab | Fires when | |---|---|---| | `ticket_created` | Ticket Creation | A new ticket matches the rule's conditions | | `ticket_updated` | Ticket Updates | An update to a ticket matches the rule's conditions (e.g. "Status is updated", "Customer replies to ticket") | If an `event` value isn't one you handle, log it and return `200`. If the body has no `event` field, the rule is misconfigured, so return `400`. ## Delivery, Retries and Idempotency - **Success** is any 2xx response. 3xx responses are followed as redirects. Anything else counts as a failure and "will automatically be retried once every 30 minutes, totaling 48 calls". Account admins get a failure email. - **Rate limit:** 1000 webhook calls per hour. Calls over the limit are queued until the next hour. - There's **no delivery ID header**, so dedupe on values you put in the body (e.g. `event` + `ticket.id` + a status or timestamp placeholder), or make your handler an upsert keyed on `ticket.id`. - Webhooks run asynchronously to the automation, and Freshdesk ignores your response body. ## Environment Variables ```bash # REQUIRED. The value you put in the rule's custom header. Generate with: openssl rand -hex 32 FRESHDESK_WEBHOOK_SECRET= # OPTIONAL. The custom header name (case-insensitive). Default: X-Freshdesk-Webhook-Secret FRESHDESK_WEBHOOK_HEADER=X-Freshdesk-Webhook-Secret ``` ## Local Development ```bash npx hookdeck-cli listen 3000 freshdesk --path /webhooks/freshdesk ``` No account required. The CLI creates a guest account on first run and gives you a public HTTPS URL to paste into the Trigger Webhook action, plus a web UI for inspecting requests. In production, Hookdeck's **Freshdesk** source type checks the header for you. You enter the header name and its exact value, and requests without them are rejected.
