You will get a complete GoHighLevel API v1 to v2 migration with zero downtime
Top Rated
Project details
GoHighLevel has officially ended support for API v1. Existing v1 integrations may still respond, but they no longer get bug fixes, security updates, or new features. Any breakage you hit now is permanent unless you migrate.
I'm a senior Laravel and Node engineer specializing in CRM integrations. I'm Top Rated on Upwork with a 100% job-success rate across multiple verified GHL projects — including a rescue job where I diagnosed an API auth issue another developer called "beyond their ability."
This project covers everything a clean v1 to v2 migration needs: a full audit of your current integration, endpoint and webhook rebuilds against v2, OAuth 2.0 setup (or Private Integration Token migration for simpler cases), custom-field remapping, sandbox validation, and a documented rollback plan. Pick the tier that matches your scope.
What you avoid:
• A migration that ships fast and breaks in three months
• Hiring someone whose first GHL project is yours
• Future v1 bugs with no support path
If you're not sure which tier you need, start with the Audit. You get a written migration plan you can use even if you hire someone else to execute it.

GoHighLevel CRM Integration Developer - Snap Fitness Happy Valley
Dawood built out our GoHighLevel CRM sub-account for another Snap Fitness club location, configured to run entirely on native GHL phone and SMS rather than our usual third-party voice platform. He set up the texting number, handled the carrier registration process, and got everything routed correctly on the first pass, no back and forth needed to sort out a routing issue. Communicative, accurate, and easy to hand a slightly different setup to and trust it'd be done right.

GoHighLevel CRM Integration Developer - Two Clubs (Snap Fitness Alexandria & Sauk Centre)
Dawood handled a two-location build for us in parallel, cloning our full GoHighLevel CRM workflow set into new sub-accounts for two gym locations, then configuring each with its own location-specific details, calendar setup, and Quo SMS webhook.
Part of this build was gated behind third-party approval timing outside his control, and he adjusted his schedule around that dependency without it turning into a bottleneck. Both sub-accounts were connected to our reporting dashboard and matched our existing build standards exactly. Solid technical work, easy to coordinate with, and reliable on a deadline. Would hire again.

GoHighLevel CRM Integration Developer - Snap Fitness Bend (3 Locations)
Dawood built out our GoHighLevel CRM across three separate Snap Fitness locations and delivered exactly what we needed.
He cloned and configured full automation workflows into three sub-accounts, handled custom webhook development for our Quo SMS integration, and connected everything to our Custom Values Manager dashboard. He also built a reporting system from scratch that pulls data across all three locations through the GHL API, processes it into conversion metrics, and visualizes it with charts inside the CVM. That piece required real problem solving, not copy-paste work.
He knows GoHighLevel at a technical level well beyond surface-level workflow building, takes feedback well, and asks good questions instead of guessing. If you need someone who can go under the hood on GHL, he is a strong choice.
I plan to keep working with him.

Snap Fitness Owatonna - CRM Sub-Account Build
Dawood did excellent work cloning and reconfiguring our GoHighLevel CRM automation system, including a custom Quo SMS webhook and dashboard integration. His work was clean enough that we used it as the template for a second client build. Professional, on time, and highly recommended.

Snap Fitness Andover - CRM Sub-Account Build
Another great project working with Dawood. He's reliable, communicates well, and delivers quality work on time. It genuinely feels like working with a coworker rather than a contractor. I'll continue bringing him onto future builds without hesitation.

Steps for completing your project
After purchasing the project, send requirements so Dawood can start the project.
Delivery time starts when Dawood receives requirements from you.
Dawood works on your project following the steps below.
Revisions may occur after the delivery date.
Kickoff and current-state audit of your GHL v1 integration
I review your sub-account, endpoints, webhooks, and integration code. You get a written audit document mapping every v1 dependency to its v2 equivalent, plus a list of breaking changes and a recommended migration order. No code changes yet.
Migration plan and scope sign-off
We agree on which endpoints get migrated first, OAuth 2.0 rebuild scope, and webhook payload handling. I lock in milestones and timelines so you know what is shipping and when. Catch any out-of-scope items before code is touched.
