There are 4 fatal infrastructure traps quietly killing GHL agencies right now. If your clients aren't completely dependent on your architecture, you are already obsolete. They will leave.
I exposed all 4 traps and exactly how to fix your sub-accounts today.

Hey guys,
If you’ve ever tried building custom integrations (with n8n, Make, etc.) using GoHighLevel’s API 2.0, you know their OAuth token management is a massive pain.
The access tokens expire every 24 hours. The standard advice online is to spin up a server, write a cron job, or pay for a third-party tool just to keep the tokens alive. And if you try asking GHL support for help, they make you fill out a 50-field form. Even experienced no-code devs struggle with this setup.
I wanted a zero-touch solution, so I built a simple Google Sheet with a Google Apps Script running behind the scenes. It takes about 5 to 7 minutes to set up, costs nothing, and handles the entire lifecycle.
Here is what the sheet does:
Once it's running, you just point your n8n or Make workflows at this Google Sheet to grab the active token whenever you need to make an API call.
I recorded a full walkthrough showing exactly how to create the Private Custom App in the GHL Developer Marketplace and connect it to the sheet.

(Note: The Apps Script runs entirely inside your own Google account, so your client IDs and tokens remain completely private to you).
Hope this saves some of you the 3 to 4 hours of headaches it usually takes to figure the GHL documentation out. Let me know if you run into any issues!

Hey everyone,
Unfortunately, the enterprise recruitment agency where I’ve served as the Lead Automation Architect for last 3+ years is closing its doors. While it’s a tough transition, I am looking to bring my enterprise-level GoHighLevel experience to a scaling agency, SaaS, or high-volume business that is hitting GHL's native limits and needs serious engineering.
Most GHL "experts" know how to build basic email campaigns and simple workflows. I specialize in bypassing native limitations, building serverless data pipelines, and engineering massive multi-tenant architectures.
Here is a breakdown of what I’ve built and managed:
1. Global Master Snapshots Architecture: Engineered and maintained enterprise V1 and V2 "Master Snapshots" to deploy uniform workflows, custom values, and trigger links, custom fields, calendars, custom menu's, dashboard updates across 150+ active sub-accounts simultaneously
2. Automated Account Provisioning: Built complex Pabbly workflows utilizing GoHighLevel's V2 API to automatically create sub-accounts, load master snapshots, and populate baseline custom values upon signup and handover to account onboarding team with Core SOP's to complete the account setup.
3. Seamless V1 to V2 Migrations: Designed and executed staged migration pipelines to update legacy V1 accounts to V2 environments without breaking live funnels
4. Custom GHL UI Modifications: Wrote custom CSS and JavaScript to hide native GoHighLevel features (like SaaS billing menus and launchpads) and embedded custom portals directly into the platform interface.
5. Distribution System (Leads): Engineered a centralized routing architecture that captured all raw leads globally, calculated daily sub-account quotas, and dynamically dripped leads based on priority weightings using cloudflare, hookdeck, google appscript, sheets and supabase
6. Global Deduplication Engine: Built logic to automatically catch duplicates across all external vendor uploads and internal routing, preventing subscribers from receiving identical leads.
7. Third-Party Vendor API Integrations: Developed API parsers and webhooks to automatically ingest high-volume applicant data from JazzHR, ZipRecruiter, and CSVBox into a centralized account and thereby distributing to subscribers accounts.
8. Supabase (PostgreSQL) Data Warehousing: Migrated massive CRM data loads into Supabase databases, building custom tables to track candidates, internal events, and telecom logs
9. Event-Driven Queuing Pipelines: Setup Cloudflare Workers and Hookdeck to catch, queue, and retry massive webhook payloads, preventing server crashes during heavy lead distribution
10. Stripe Billing API Syncing: Integrated the Stripe API into your custom databases to pull customer subscriptions, product variations, and billing cycles to power your internal billing dashboard
11. Telnyx Outbound SMS & Voice Integration: Bypassed native LC telecom limits by integrating Telnyx directly into workflows via API, severely dropping costs for SMS and Voicedrops
12. Apple iMessage Fallbacks (Hiublue): Designed fallback engines routing failed SMS communications directly through Apple iMessage to completely bypass telecom carrier spam filters
13. "AM Message Router" Application: Engineered a dynamic GoHighLevel marketplace app to seamlessly switch contacts between standard SMS, Telnyx, and iMessage natively
14. Dynamic Calendar Caching (Redis/Upstash): Built a system using Upstash to store location IDs and dynamically render calendar availability via API, replacing hardcoded CRM links
15. Advanced Link Cloaking: Configured Cloudflare redirect scripts using 4-digit location ID combinations to securely route users and prevent carrier blacklisting and get away from standard trigger links to prevent spam filters.
16. RAG-Powered Custom Support Agents: Built N8N workflows integrated with vector databases to load helpdesk articles and automatically answer customer support tickets.
17. Conversational AI Bots: Developed isolated AI bots designed specifically to respond to interested leads and convert based on intent and pipeline stages using RAG powered knowledge database in supabase and N8N and GHL V2 API.
18. Inbound Sentiment Classifiers: Engineered automated workflows to read inbound candidate messages and use LLMs to classify their intent (e.g., DND, questions, hostile) directly into Supabase
19. Deep Behavioral Tracking: Wrote custom JavaScript injected into landing pages to capture granular engagement metrics—such as precise page load speeds, scroll depth percentages, and video watch duration—pushing the data back into the CRM
20. Automated Reputation Management: Deployed a web-scraping AI via N8N that actively searched hiring company names on Google to perform sentiment analysis and flag negative PR links in real-time
21. Business Intelligence Dashboards: Wrote advanced SQL queries combining CRM data and built live, multi-tenant performance dashboards in Databox and Looker Studio
22. Custom Front-End Portals: Utilized Bolt.new and React/Vue to build independent full-stack web applications, such as a custom task management portal for the team to monitor the AI replies, fix the answers and keep the AI knowledge base clean and updated
23. Agile Sprint Management: Managed the Core Dev and GHL Dev team backlogs using ClickUp and Canny.io. Routinely moved tasks through the pipeline, prioritized bug fixes, closed completed items, and structured 90-day roadmaps
24. Leading Meetings: Regularly attended and led daily Dev Standups, as well as weekly Leads and Subscribers syncs, to communicate complex technical updates to non-technical stakeholders.
25. Engineering Quality Control (QC): Built exhaustive Standard Operating Procedures (SOPs), testing checklists, and recorded hundreds of Loom videos to train the QC team on how to safely deploy workflow updates and audit accounts.
26. Hiring & Developer Management: Personally screened, hired, and directed external front-end and back-end engineers, database specialists and no-code developers. Conducted code reviews, managed GitHub repository access, oversaw database schema designs, and delegated complex tasks.
My Tech Stack: GoHighLevel (V2 API & OAuth), Supabase, N8N, Pabbly Connect, Hookdeck, Cloudflare Workers, Google Apps Script, Telnyx, and custom JavaScript/HTML/CSS, clickup, canny.io, bolt.new, etc
