| GoHighLevel API v2 Development | Builds against REST endpoints covering contacts, opportunities, conversations, calendars, and payments. Handles pagination, rate limits, and response validation across every call. Experienced in CRM API integration patterns that hold up at volume. | Your integration keeps working as record counts grow, rather than timing out once the account fills up. |
| OAuth 2.0 and Authentication | Implements Authorization Code grant flows, access and refresh token handling, and scope permission design across every integration. Configures Marketplace App registration or Private Integration Tokens based on how many sub-accounts the integration reaches. | Access stays valid without manual reconnection, and each integration holds only the permissions it actually needs. |
| Marketplace App Development | Builds private apps scoped to single sub-accounts and public apps prepared for GoHighLevel review, which carries strict requirements around install flows and scope design. Covers install and uninstall flows, custom sidebar panels in the agency view, and full submission package preparation. | You get a properly packaged app rather than a script, which means it installs cleanly across client accounts. |
| Multi-Tenant Data Separation | Designs client data isolation and per-install scope permissions before any code is written. Handles location-level access boundaries so an integration built for one sub-account survives being deployed across the rest. | Your agency installs the same integration across dozens of client accounts without data crossing between them. |
| Payments and Commerce Integration | Payment gateway connections, subscription and recurring billing logic, invoice and estimate syncs into accounting systems, order form and upsell logic. | Revenue lands in your accounting system without manual reconciliation. |
| Multi-Channel Messaging Architecture | Consolidated conversation handling across SMS, WhatsApp, Messenger, Instagram DM, and live chat, with routing rules, threading, and delivery-state handling. | Every channel writes to one customer record with no duplicate threads. |
| Webhook Engineering | Webhook delivery is never guaranteed on a busy account. Sets up event subscriptions with signature verification, retry logic, idempotency handling, and dead-letter queues for failed deliveries. | Events do not silently disappear when a receiving system is briefly unavailable. |
| Custom Objects and Data Modeling | Designs custom objects, custom values, and field relationships that reflect how your business actually tracks work. Maps fields between GoHighLevel and external systems before any data moves. | Your data structure matches your operation, so reporting stays accurate as processes change. |
| Workflow and Automation Architecture | Builds multi-branch conditional logic, cross-object triggers, and sequences calling external services mid-flow. Designs workflow automation with trigger ordering planned before the build starts. | Complex automations fire predictably at volume, even when several conditions overlap. |
| AI Feature Integration | Wires Voice AI, Conversation AI, and AI Employee into workflow logic, custom objects, and external systems. Handles conversation routing, qualification criteria, and how AI-generated actions write back to your pipeline. | AI agents update the right records and trigger the right next step, so conversations they handle stay inside your process. |
| SaaS Mode and Billing Integration | Configures automated sub-account provisioning, Stripe Connect billing, pricing tier logic, and client onboarding flows under your agency branding. | Clients sign up, get provisioned, and get billed without your team handling any step manually. |
| Third-Party Integration | Connects GoHighLevel to payment gateways, accounting platforms, booking engines, communication services, and proprietary internal tools through REST and GraphQL APIs. | Operational data lands in one place, which removes duplicate entry from your team's daily work. |
| Backend Development | Builds server-side services in Node.js, Python, and PHP that sit alongside GoHighLevel, handling business logic the platform does not expose. | Logic too complex for the workflow builder still runs, without waiting for a platform feature release. |
| Database Design | Works in PostgreSQL, MySQL, and MongoDB on schema design, indexing, and query optimization for systems syncing with GoHighLevel. Applies architecture patterns built for multi-system data flow. | Your external systems handle sync volume without slow queries or reporting failures. |
| Security Best Practices | Applies data encryption, role-based access controls, audit logging, input validation, and OWASP-aligned secure coding across every integration point. | Client data stays protected and your integrations hold up under compliance review. |
| CI/CD and DevOps | Maintains pipelines in GitHub Actions, Jenkins, and GitLab CI for automated builds, testing, and staged deployment of integration code. | Updates ship faster with lower risk of breaking a live integration during release. |
| Platform Change Monitoring | Tracks GoHighLevel API deprecations, endpoint changes, webhook delivery failures, and token expiry across every live integration. Flags what needs updating before a platform release breaks it. | Your integrations keep running through platform updates, with fixes planned ahead of a release instead of after an outage. |
