About this gig

Are you finding it challenging to maximize the potential of GoHighLevel for automation, integrations, or scaling your SaaS or agency?


Hello there, I'm Grayson. I assist businesses in transforming GHL into a robust growth engine by providing tailored app development, API integrations, and sophisticated automation systems that generate leads, enhance conversions, and reduce manual tasks.


Emphasizing reliability, performance, and sustainable scalability, I create solutions that not only function effectively but also evolve alongside your business.


What I can build for you:

  • GoHighLevel Marketplace App development (submission ready)
  • Third party API integration with GoHighLevel
  • Custom GHL app with configuration UI panel
  • OAuth2 authentication setup for GHL apps
  • Webhook event handling and real time triggers
  • Zapier, Make (Integromat), and Pabbly GHL connections
  • Custom workflow actions and triggers via GHL API
  • CRM data sync between GHL and external platforms
  • White label app setup for agencies



I also optimize existing setups; no need to rebuild from scratch.


Lets build a scalable, automated system that saves time and increases revenue. Message me to get started.
