The GoHighLevel integration, in detail
Power CRM is not a tool that talks to GoHighLevel. It is a marketplace app that installs into it — OAuth chooselocation, SSO, signed webhooks, and a sync engine designed around the CRM's rate limits rather than against them.
How the connection is made
- Install from the marketplace. The app is listed on the GoHighLevel marketplace and installed against your agency.
- Authorize with chooselocation. The standard GoHighLevel OAuth flow. You pick the locations Power CRM may access.
- Tokens are stored and refreshed. A token-refresh worker keeps the OAuth connection alive so the integration does not silently die.
- Sub-accounts are discovered. A client-discovery worker finds new locations from your installs. You do not add them by hand.
- Backfill, once. A one-shot sync backfill pulls historical data for an agency that has been on GoHighLevel for years.
- Your team is already logged in. GoHighLevel SSO means opening the app inside the CRM iframe signs your team straight in — no second password.
What it touches
The GoHighLevel objects Power CRM actually reads and writes today.
Scope disclosure: the install currently requests the full GoHighLevel marketplace scope set — 140 scopes, requested unconditionally at install regardless of which modules you enable, including payments, charges, blog-write, social-account and Twilio-account scopes that the product does not use today. We list every one of them, by category, in the privacy policy. The objects below are what the app exercises.
Contacts
Read and write, including contact custom fields, tags and notes.
Location custom fields
Read and write, with folders.
Location custom values
Read and write, synced bidirectionally against contact custom fields.
Locations / sub-accounts
Discovered automatically from your installs.
Users
Pulled into the app so your roster mirrors the CRM.
Calendars & appointments
Calendars, free slots, appointment CRUD and appointment notes.
Conversations & messages
Inbound and outbound message events.
Companies / agencies
The agency context the app installs against.
The sync workers and their cadence
Every worker's state, last run and result is visible in the app, with a manual trigger and a force-sync.
| Worker | Cadence | Direction |
|---|---|---|
| Contact sync | Every 5 minutes | GoHighLevel → Power CRM |
| Custom fields sync | Every 10 minutes | GoHighLevel → Power CRM |
| Field push worker | Every 30 seconds | Power CRM → GoHighLevel |
| Appointment sync | Every 5 minutes | GoHighLevel → Power CRM |
| Field-value sync | Scheduled | Bidirectional |
| Token refresh | Continuous | OAuth |
| Client discovery | Background | GoHighLevel → Power CRM |
| Website crawl | Background | Web → Power CRM |
| Onboarding reminders | Scheduled | Outbound to clients |
Webhooks handled
In production, every inbound webhook is signature-verified (RSA-SHA256 against GoHighLevel's published public
key) and an unsigned or invalid request is rejected with a 401. Including the one that matters most:
app.uninstall — on uninstall we delete ten
collections for that location: the installation record, the stored OAuth tokens, webhook events and logs, audit
logs, the contact field cache, the cached GoHighLevel custom fields and field folders, the pending field-sync
queue and the location record. With no installation or token left, syncing stops for it. The workers themselves
are not selectively stopped, and the tokens are deleted locally rather than revoked via a GoHighLevel revocation
endpoint. Other records (clients, appointments, sync cache, conflicts, contact mappings, custom field values and
history, crawled site content, cached brand data, documents, meetings, leads, fax settings) are retained until
you request full deletion — the privacy policy lists exactly
what each covers.
- contact/create, contact/update, contact/delete
- contact/customfield, contact/tag
- message/inbound, message/outbound
- appointment/create, appointment/update, appointment/delete
- location.create, location.update
- app.uninstall
