About this gig
WELCOME TO MY GIG
Need custom GoHighLevel (GHL) Private Apps, advanced API 2.0 integrations, or custom Webhook handlers? Native GHL workflows and standard Zapier connections often fall short for complex business logic, custom SaaS sub-account tools, and multi-location setups.
I build secure, scalable backend middleware, OAuth 2.0 Private Apps, and two-way API data syncs tailored to your exact agency workflow.
️Technical Services Offered:
GHL API 2.0 & Private Apps:
- Custom GoHighLevel Private Apps with OAuth 2.0 authentication
- Custom Marketplace integrations & SaaS sub-account automation
- REST & GraphQL API data mapping, contact syncing, & custom fields
Webhooks & Custom Backend Code:
- Custom HTTP Webhook listeners, JSON payload parsing, & error handling
- Middleware development (Node.js, Python, Serverless) for two-way syncs
- Custom payment gateway, CRM, or external database connections
Why Choose Me?
- GHL Architecture Expert: Up to date with HighLevel API 2.0 standards
- Secure Code: Enterprise-grade OAuth token handling & error recovery
- Agency-Ready: Tested across single-location and sub-account setups
Please contact me before ordering with your spec details. Let's integrate!

FAQ
Do you use HighLevel API 2.0 and OAuth 2.0 authentication?
Yes! I build strictly using GoHighLevel's official API 2.0 and OAuth 2.0 architecture. This ensures secure token generation, location-level access permissions, stable long-term connectivity, and full compliance with HighLevel’s latest developer standards.
Can your custom webhook or API integration work across multiple sub-accounts?
Absolutely. I design scalable Private Apps and serverless middleware that can handle multi-location routing, dynamic agency-level OAuth tokens, and sub-account specific webhook payloads without hardcoding individual credentials.
Where is the custom backend middleware hosted?
Custom Webhooks and API scripts can be hosted on your preferred cloud provider (AWS, Render, Vercel, Heroku, or digital agency server). I deliver clean, documented code and assist with complete server deployment to guarantee seamless operation.
