GoHighLevel Expert & GHL API Developer — Eliser Eguia Tual

What I build in GoHighLevel

Most GoHighLevel work falls into two categories. The first is configuration a business could technically do itself but never gets right: pipeline stages that reflect how deals actually move, funnels that capture the fields sales genuinely needs, and follow-up sequences that trigger on stage changes rather than on a calendar.

The second is the work the interface does not expose at all — syncing opportunities to an external database, pushing call outcomes back into a contact record, generating documents from custom fields. That requires the GoHighLevel API, and it is where most GHL projects stall.

• CRM and pipeline architecture — stages, custom fields, and the automations that move records between them
• Sales funnels and landing pages wired to the CRM rather than sitting beside it
• Email and SMS campaigns triggered by pipeline stage, tag, or form submission
• Custom GHL API integrations — reading and writing contacts, opportunities, calendars, and custom values
• Sub-account setup and configuration for agencies managing multiple clients

The problem this usually solves

The pattern is nearly always the same. Leads arrive from several places — a form, a Facebook ad, a phone call, a spreadsheet someone maintains by hand — and someone is responsible for chasing each one. That person is busy, so follow-up is inconsistent, and the leads that go cold are invisible because nothing recorded that they were ever warm.

A properly built GoHighLevel setup makes follow-up a property of the system rather than of a person's attention. The lead enters a pipeline, the pipeline triggers the sequence, and the sequence runs whether or not anyone remembers.

Working with the GoHighLevel API

Custom integrations need explicit decisions about authorization scopes, record mapping, API limits, token refresh and error handling. Check these against the current HighLevel documentation for the actual endpoints and authentication method used by your project. HighLevel documents rate limits per Marketplace app and resource for its OAuth public API 2.0 endpoints.

I typically wire GHL to the rest of a stack through n8n or Make, keeping the orchestration outside GoHighLevel so it stays debuggable and portable. When the logic gets heavy enough, it moves into a Next.js application talking to the API directly.

Common questions

Can GoHighLevel connect to tools it has no native integration for?

Yes, through the GHL API or a middleware layer like n8n, Zapier, or Make. Native integrations cover the common cases; anything else needs webhooks and API calls, which is most of the custom work I do.

What is the difference between a GoHighLevel setup and a GoHighLevel integration?

A setup is configuration inside the platform — pipelines, funnels, campaigns, calendars. An integration connects GoHighLevel to systems outside it, which requires the API and usually some code.

Do you work with agencies running multiple GoHighLevel sub-accounts?

Yes. An agency integration needs to account for each location’s permissions, records and API limits. Share the sub-accounts and data flows involved so I can assess the scope.
