Custom apps and integrations on GoHighLevel.
We're senior software engineers who specialize in GoHighLevel. When the platform doesn't do what you need out of the box, we extend it — either as an app on the GHL Marketplace, or as a direct integration with your stack via the GHL public API and webhooks.
Two shapes of work. One set of senior hands.
Most GoHighLevel projects come down to one of these. Same hourly rate, same private Slack channel, the person who scoped it doing the build.
Apps for the GHL Marketplace
Listed and unlisted apps built to the GoHighLevel Marketplace spec — OAuth-based, embedded inside the GHL UI, with workflow actions and pages your users see without ever leaving the platform.
- Public Marketplace listings
- Private / white-label apps for agencies
- Custom workflow actions & triggers
- Custom menu links and embedded pages
- OAuth 2.0 lifecycle & token rotation
Custom integrations
Direct integrations between GoHighLevel and the rest of your stack. Built against the GHL public REST API and webhooks — no Zapier middleman, no per-task billing, no five-minute polling delays.
- REST API integrations in both directions
- Real-time webhook receivers
- Retry, idempotency, and replay handling
- Connections to internal CRMs, billing, ERPs
- Data sync to Snowflake, BigQuery, Postgres
Apps that live inside GoHighLevel.
A Marketplace app is a piece of software that runs alongside GoHighLevel. It's installed by a sub-account or agency, authorized via OAuth, and given permission to read data, write data, react to events, and render UI inside the GHL workspace itself. To the end user it feels like a native GHL feature — but it's running on your infrastructure, doing whatever you built it to do.
We've shipped a public app on the GoHighLevel Marketplace, and we build private apps for agencies that want to distribute internal tools across their sub-accounts without writing the platform code themselves. The work spans backend (Node, Cloudflare Workers, Postgres, queues), frontend (embedded React inside the GHL chrome), and the integration layer (OAuth, scopes, refresh tokens, app lifecycle webhooks).
Components we ship
- Custom workflow actionsYour own block in the GHL workflow builder. Runs against your API on every execution.
- Custom workflow triggersFire workflows from events outside GHL — your billing system, your data warehouse, anything.
- Custom menu linksSurface your app's UI as a top-level sub-account menu item.
- Custom pagesFull-bleed embedded pages — your React UI rendered inside the GHL chrome.
- OAuth 2.0 lifecycleInstall, refresh, scope changes, uninstall — handled end to end.
- Lifecycle webhooksSubscribe to GHL events with verified signatures and idempotent handlers.
When GHL needs to talk to something else.
Most clients reach this point the same way: GoHighLevel holds the customer-facing motion — forms, pipelines, workflows, SMS — and something else holds the rest. A custom billing system. An internal CRM. A partner API. A data warehouse. The two need to stay in sync, and the sync needs to be reliable enough to bill against.
Zapier and Make are fine for trivial cases. They fall over the moment you need transactional guarantees, retries, idempotency, or low-latency reaction to events. We build the direct integration instead — code, not no-code — hosted on Cloudflare Workers, AWS, or your own infrastructure, with observability you can actually open and read.
What we handle
- REST API integrationsBoth directions. Push to GHL, pull from GHL, sync entities, batch jobs, paginated reads.
- Webhook receiversVerified, idempotent, retried, replayable. Drop-and-resume safe.
- OAuth 2.0 flowsConnect GHL to your own product, or to third-party services on your clients' behalf.
- Event bridgesGHL ⇄ Stripe, Twilio, Calendly, Segment, Snowflake, BigQuery, Postgres, anything with an API.
- Rate-limit handlingYour integration shouldn't melt the first time GHL throttles you.
- ObservabilityStructured logs, dashboards, alerts — so you can see what's happening without DMing us.
Same hourly model. Estimate, build, ship.
Small extensions are usually ad-hoc hourly work — a custom workflow action is often 8–16 hours, and you pay only for productive time, logged to the tenth of an hour. Larger builds (a full Marketplace app, a multi-system integration) are scoped under a formal SOW with a fixed estimate and milestones. Either way, the work happens in your private Slack channel, with the same senior person across scoping and shipping.
The questions we get before scoping a build.
Can you build a public app for the GoHighLevel Marketplace?
Yes. We've shipped a listed Marketplace app and know the OAuth lifecycle, custom UI components, workflow actions, and review process. We can build yours and submit it for review, or hand off a code-complete app for your team to publish.
Can you build a private or white-label app for our agency?
Yes. Unlisted Marketplace apps work the same as public ones — you install them across your sub-accounts without the app appearing in the public listing. Most agency-internal tools and white-labeled add-ons are built this way.
Can you integrate GoHighLevel with our internal system?
Almost always, yes. If your system exposes an API (REST, GraphQL, gRPC) or accepts webhooks, we can build the integration. If it doesn't, we build a shim. The work is bounded by what's exposed on both sides — we'll tell you up-front if a particular sync is impossible or requires a workaround you should know about.
What's the difference between a GHL workflow and a custom integration?
A GHL workflow is no-code configuration that runs inside GoHighLevel's runtime — drag-and-drop actions in the workflow builder. A custom integration is code we host (on Cloudflare Workers, AWS, your own infrastructure) that talks to GHL via API and webhooks. Workflows are great for in-platform automation; custom integrations are how GHL talks to systems outside itself.
Do we have to use Zapier or Make for integrations?
No. Zapier and Make are fine for trivial, low-volume work, but they get expensive at scale, they introduce latency, they don't handle complex retries or idempotency well, and you don't own the code. A direct integration is usually cheaper after the first 6–12 months and is yours to keep forever.
Where do you host the integration code?
Default is Cloudflare Workers — fast, cheap, no servers to manage, and the right shape for the kind of webhook and API work most integrations need. We also work on AWS, Vercel, Fly.io, or your own existing infrastructure if you have a stack you want it deployed into.
Do you do ongoing maintenance after a build ships?
Yes. The same hourly model covers maintenance, fixes, and small extensions after launch. You pay only for productive time. No retainer is required, but most builds end up with one to four hours a month of follow-up work in the first quarter.
Let's scope it on a 20-minute call.
If it's a small build, you'll leave the call with an hour estimate. If it's a big one, we follow the call with a written SOW. Either way, you get a price before any work starts.
