How to Configure Unique Fields in GoHighLevel Custom Objects

When you move complex workflows from tools like ClickUp into GoHighLevel, keeping your data clean becomes critical. One powerful feature that helps you avoid duplicates is the unique field setting on custom objects. This guide explains how unique fields work, how to enable them, and how to troubleshoot common errors so your GoHighLevel account stays accurate and reliable.

What Are Unique Fields in GoHighLevel Custom Objects?

In GoHighLevel, a unique field on a custom object is a field that cannot share the same value with any other record in that object. This is essential when you want to enforce one-of-a-kind identifiers, such as:

  • Order numbers
  • Booking IDs
  • Membership IDs
  • External system reference IDs

When you mark a field as unique, GoHighLevel checks that field’s value each time a record is created or updated. If the value already exists in another record, the platform blocks the action and shows an error.

Key Rules for Unique Fields in GoHighLevel

Before you start editing custom objects, it is important to understand how unique fields work in GoHighLevel so you can design consistent data structures.

Supported Field Types for Unique Constraints in GoHighLevel

GoHighLevel currently supports unique constraints on a specific set of field types in custom objects:

  • Number fields (integer or numeric values)
  • Text fields (single-line text)

Other field types, such as lookup relationships, multi-select fields, or date fields, cannot be marked as unique in custom objects. If you need uniqueness around those values, store them in a text or number field that can be configured as unique.

Scope of Uniqueness in GoHighLevel Custom Objects

The uniqueness rule applies only within the same custom object. This means:

  • Two different custom objects can have the same unique field value without conflict.
  • Only records inside the same custom object are checked against each other for duplicates.

For example, a unique field called Order ID in an Orders object does not conflict with a field named Order ID in a different custom object.

How to Enable a Unique Field in GoHighLevel Custom Objects

Follow these steps to mark a field as unique in your GoHighLevel custom object configuration.

Step 1: Open the Custom Object in GoHighLevel

  1. Sign in to your GoHighLevel account.
  2. Navigate to the section where custom objects are managed (under the developer or schema configuration area for your account).
  3. Select the custom object where you want to define a unique field.

Step 2: Choose a Supported Field Type

  1. Locate an existing field of type Number or Text, or create a new one.
  2. Ensure the field will store a value that must be unique across all records in this object, such as a reference ID.

Step 3: Mark the Field as Unique

  1. Open the settings or configuration panel for the chosen field.
  2. Find the option to set the field as unique.
  3. Enable the unique setting and save the field configuration.

From this point forward, GoHighLevel will prevent any record in this custom object from saving if it would cause a duplicate value in the unique field.

How GoHighLevel Handles Duplicate Unique Field Values

Once a field is marked unique, GoHighLevel performs a validation check every time the field is set or updated. Understanding this behavior helps you build reliable automations and integrations.

Behavior on Record Creation

When a new record is created in a custom object:

  • If the unique field is empty, the record can be created (unless you also set the field as required).
  • If the unique field has a value that does not exist in any other record in that object, the record is created successfully.
  • If the unique field has a value that already exists, GoHighLevel blocks the creation and returns a unique field validation error.

Behavior on Record Update

When an existing record is updated:

  • If you do not change the unique field value, the update succeeds as long as other validations are met.
  • If you change the unique field to a new value that does not exist in another record, the update succeeds.
  • If you change the unique field value to one already used in another record, the update fails with the same unique field validation error.

How to Troubleshoot Unique Field Errors in GoHighLevel

When working with custom objects, especially through automations or API calls, you may encounter errors related to unique fields. Here is how to diagnose and resolve them.

Common Unique Field Error Messages in GoHighLevel

Typical symptoms of unique field issues include:

  • Error messages indicating a duplicate value on a unique field.
  • Automations or workflows failing when attempting to create or update custom object records.
  • API responses returning status codes that highlight a validation failure on a unique field.

Steps to Resolve Duplicate Unique Field Issues

  1. Identify which field is unique.
    Check the custom object configuration to confirm which field or fields are marked as unique.
  2. Search for existing records.
    Use filters or search tools inside GoHighLevel to find any record with the same value in that unique field.
  3. Decide whether the duplicate is valid.
    If the new record is a true duplicate, keep the existing record and update it instead of creating a new one. If both records need to exist, change one of the values.
  4. Update data or logic.
    Adjust your data so each record has a distinct value for the unique field. If you are using integrations or webhooks, modify the logic that generates the unique identifiers.

Best Practices for Unique Fields in GoHighLevel Custom Objects

To avoid recurring problems and make the most of unique fields in GoHighLevel, follow these guidelines.

Design Unique Fields Carefully

  • Choose values that are naturally one-of-a-kind (such as IDs from an external system or sequential numbers).
  • Avoid using names or labels as unique fields since they can change or be reused.
  • Document which fields are unique in your internal process documentation so team members and developers are aligned.

Validate Data Before Sending It to GoHighLevel

  • If you integrate GoHighLevel with other platforms via API or automation, validate unique field values before making a create or update request.
  • Implement checks in external systems to ensure they do not generate duplicate identifiers.

Monitor and Audit Custom Object Data

  • Regularly review records in your custom objects to confirm that unique fields are behaving as expected.
  • When you see frequent errors, evaluate whether your chosen unique field is appropriate or whether your workflow needs refinement.
