HighLevel does not currently offer a public Timezone API. However, you can manage time zones through the platform’s built-in features. You can manually set the time zone for your agency, sub-accounts, users, and
calendars.
The HighLevel Timezone API solves that problem. It allows you to read, update, and manage time zones for contacts, users, and calendars directly through GoHighLevel. This guide explains how it works, why it matters, and how you can use it to maintain consistent and accurate data across your entire system.
What Is the HighLevel Timezone API
The HighLevel Timezone API is part of the GoHighLevel REST API that lets developers access or modify time zone information stored inside accounts.
In simple words, it helps you
- Retrieve the current time zone for contacts, accounts, and users
- Update or synchronize time zones between GoHighLevel and other systems
- Make sure automations and appointments happen at the right local times
Normally, HighLevel applies a time zone based on account settings, but data from outside systems such as Zapier, Google Calendar, or webhooks may use different formats. That can create confusion. The Timezone API helps align everything properly.
Why Time Zones Matter in GoHighLevel
For businesses that serve clients in multiple regions, time zones affect everything from calendar bookings to workflow automation.
Imagine this scenario. A client in London receives an appointment reminder meant for 9 AM local time, but your account is set to Eastern Standard Time. The reminder could go out five hours too early.
Or a workflow that triggers “Send at 10 AM” might send emails or texts at the wrong hour depending on the contact’s time zone.
This kind of mismatch causes missed meetings and poor customer experiences. Managing time zones through the HighLevel Timezone API keeps all systems running on schedule.
How GoHighLevel Stores Time Zones
GoHighLevel tracks time zones at three levels.
- Account level
Each agency or sub account has a default time zone under its settings. All new users and calendars inherit this by default. - User level
Each user such as a team member or client can have their own time zone. It controls how their calendar and appointments display. - Contact level
Each contact record can store a time zone. This ensures messages and workflows run according to that person’s local time.
The HighLevel Timezone API allows you to read and update all three levels when needed.
How to Access the HighLevel Timezone API
To use the Timezone API, connect through GoHighLevel’s REST API with your agency or sub account key.
Step by step
- Log into your GoHighLevel agency dashboard.
- Go to Settings and click API Keys.
- Copy your API key.
- Use the key in the authorization header of your API requests.
Example header
Authorization: Bearer your_api_key_here
You can now call endpoints like /users, /contacts, or /calendars to read or edit time zone data.
Example: Retrieving a Contact’s Time Zone
If you want to check the time zone for a contact, use this endpoint
GET https://rest.gohighlevel.com/v1/contacts/{contactId}
A typical response includes
"timeZone": "America/New_York"
This shows the time zone currently assigned to that contact.
Example: Updating a Contact’s Time Zone
To update the time zone, for instance after importing leads from another CRM, use
PUT https://rest.gohighlevel.com/v1/contacts/{contactId}
Include the updated field
{
"timeZone": "Europe/London"
}
After this change, all future automations and reminders will use the correct local time for that contact.
Managing Time Zones for Users and Calendars
You can also retrieve or update time zones for users or calendars in a similar way.
Get user time zone
GET https://rest.gohighlevel.com/v1/users/{userId}
Update user time zone
PUT https://rest.gohighlevel.com/v1/users/{userId}
{
"timeZone": "Australia/Sydney"
}
Get calendar time zone
GET https://rest.gohighlevel.com/v1/calendars/{calendarId}
Updating a calendar ensures appointments display correctly for both the client and the user.
Common Time Zone Issues
1. Appointments showing incorrect times
Usually caused by different time zones between user and calendar. Make sure they match.
2. Workflows firing at the wrong hour
Check the contact’s stored time zone. If missing, update it before automation runs.
3. Imported contacts set to UTC
When bringing in data from other CRMs, use the API to assign the correct local zone on import.
4. Webhooks not converting times
Some integrations send UTC timestamps. Convert them to local time before updating HighLevel.
Best Practices for Working with Time Zones
- Always store time zones in IANA format such as
America/New_YorkorEurope/Paris. - Set the account default to your primary client region.
- Assign the contact’s time zone as soon as you create the record.
- Keep calendars and user profiles synced.
- Run regular checks to confirm consistent data.
These steps prevent confusion and ensure automations, reminders, and appointments all fire correctly.
Why the Timezone API Matters for Agencies
If you manage clients across regions, manually adjusting time zones is risky and time consuming. The HighLevel Timezone API automates this and keeps your system accurate.
For example, you can
- Automatically assign the right time zone when a lead signs up
- Adjust workflow triggers based on local time
- Sync Google Calendar and HighLevel calendars
- Generate clean, consistent reports across accounts
When your data stays consistent, scheduling errors disappear and client trust grows.
