WHMCS Support Ticket Creation
Receives chat queries via webhook, uses Gemini to extract details, validates the department against WHMCS.
What it does
You get instant support ticket creation when customers send queries via webhook, as the agent uses Google Gemini to extract key details like name, email, issue description, and priority. It automatically validates your department against WHMCS data and generates structured tickets in the system without manual entry.
Step by step
- Configure an HTTP webhook node in n8n to listen for POST requests from external sources.
- Set up a Google Gemini node with a system prompt defining the JSON schema for extracting name, email, issue, and priority.
- Create an HTTP Request node configured to call the WHMCS API endpoint for listing departments to validate inputs.
Where the LLM does the work
- Craft the specific prompt instructions that guide Gemini to accurately parse unstructured customer queries into structured fields.
- Define the tone and language rules in the system message so the AI maintains a professional and helpful demeanor during context retention.
- Design error-handling prompts for Gemini to request clarification if critical details like email format or department validity are ambiguous.
Watch out for
Webhook payloads might contain HTML or special characters that break JSON parsing, so sanitize input strings in n8n before passing them to the AI model.
Session memory can cause context overflow with long conversations, so implement a token limit check or truncate history in n8n to prevent API errors.

You are helping me build the following AI agent workflow. ## Goal WHMCS Support Ticket Creation: Receives chat queries via webhook, uses Gemini to extract details, validates the department against WHMCS. ## Specification - What it does: You get instant support ticket creation when customers send queries via webhook, as the agent uses Google Gemini to extract key details like name, email, issue description, and priority. It automatically validates your department against WHMCS data and generates structured tickets in the system without manual entry. - Trigger: Triggered by an event (Event · on customer chat message) - Autonomy: Fully hands-off - Expected setup effort: about an afternoon - Tools/services involved: - n8n: Workflow orchestration platform - Google Gemini Chat Model: Natural language processing and information extraction - WHMCS API: Creating support tickets and fetching departments ## Known pitfalls, handle each one explicitly in your implementation 1. Webhook payloads might contain HTML or special characters that break JSON parsing, so sanitize input strings in n8n before passing them to the AI model. 2. Session memory can cause context overflow with long conversations, so implement a token limit check or truncate history in n8n to prevent API errors. ## Reference implementation https://n8n.io/workflows/7960 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Automation Platform than n8n?
Yes. n8n is only the example automation platform in this recipe. The same flow works with Home Assistant. Swap the automation platform connection and keep the rest of the setup as written.
Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
