How to Use Voice AI Custom Variable Support in GoHighLevel
ClickUp users who are moving into advanced automation often look for similar flexibility in GoHighLevel. This guide explains, step by step, how to use custom variables in Voice AI prompts so you can personalize automated calls and keep your data consistent across your account.
The instructions below are based on the official Voice AI custom variable support documentation and will help you implement variables correctly, avoid common issues, and structure reliable prompts.
Understanding Voice AI Custom Variables in GoHighLevel
Voice AI custom variables in GoHighLevel let you dynamically insert contact and system data into your call prompts. Instead of using static text, you can reference fields from the contact record or from other system entities.
When the Voice AI call runs, these variables are replaced with real values, allowing the agent to speak personalized content while following a single reusable prompt template.
Where Voice AI Custom Variables Work in GoHighLevel
Custom variables for Voice AI can be used in:
- The main Voice AI prompt body
- Call summaries
- Disposition notes and follow-up details
Each of these areas can pull in data from contact fields or certain system properties supported by GoHighLevel.
Types of Voice AI Variables Supported in GoHighLevel
GoHighLevel supports different categories of variables inside Voice AI prompts. Using the correct syntax is essential for the variable to resolve properly during a live call.
Contact-Level Variables in GoHighLevel Voice AI
Contact variables reference fields stored on the individual contact record. These are the most common variables used in prompts. You can insert them using the standard contact variable format documented in the platform.
Examples of contact fields that may be used (when available in your account) include:
- Contact name
- Phone number
- Email address
- Custom contact fields you have configured
Always make sure the contact record actually contains the value you reference so the Voice AI can deliver a coherent message.
System and Prompt Variables in GoHighLevel Voice AI
In addition to contact data, GoHighLevel Voice AI supports variables that relate to the call or workflow context. These can include system-level details such as:
- Call direction or purpose
- Campaign or workflow source
- Agent or business information when configured through available fields
Check your platform’s variable picker and official documentation to confirm which system variables are currently supported for Voice AI prompts in your account.
How to Insert Custom Variables in a GoHighLevel Voice AI Prompt
Follow these steps to properly configure variables inside a Voice AI prompt in GoHighLevel:
Step 1: Open the Voice AI Configuration
- Log in to your GoHighLevel account with appropriate permissions.
- Navigate to the Voice AI or call automation section where your agent is configured.
- Select the Voice AI agent or workflow you want to edit.
Step 2: Access the Prompt Editor
- Locate the main prompt or script configuration area for your Voice AI agent.
- Open the editor where you define the instructions and conversation guidance.
- Identify the sections where you want to reference contact or system data.
Step 3: Add Contact Variables to the Prompt
- Place your cursor where the dynamic data should appear.
- Use the variable selector (when available) or type the correct contact variable syntax as shown in the official Voice AI custom variable documentation.
- Ensure each variable name matches the field you intend to use.
The Voice AI will replace these variables in real time with values from the contact record at the moment the call is made.
Step 4: Add Variables to the Call Summary and Disposition
- Open the summary and disposition sections associated with the Voice AI configuration.
- Insert variables in the same supported format to capture context such as the contact name, call result, or other available data.
- Save your changes so the Voice AI can automatically generate structured notes and summaries.
Best Practices for Voice AI Prompt Variables in GoHighLevel
To keep your Voice AI prompts reliable and easy to maintain, follow these best practices when working with variables in GoHighLevel.
Use Clear and Stable Variable Names
Before using a field in a Voice AI prompt, confirm that:
- The field exists across all relevant contacts.
- The variable name in the prompt matches the variable name in the system.
- You do not rename or delete critical fields without updating the prompt.
Provide Fallback Logic in Prompt Wording
While the Voice AI system itself replaces supported variables, you should write your prompt text in a way that sounds natural, even if a field is missing. For example, structure sentences so the agent can proceed gracefully if a particular value is blank.
Test Your GoHighLevel Voice AI Variables
Before deploying an automation, always test:
- Run test calls with sample contacts that have complete data.
- Verify that each variable resolves correctly in the conversation.
- Review call summaries and disposition notes to ensure variables populate as expected.
If a variable does not resolve, double-check spelling, availability of the field on the contact, and whether that variable type is supported in Voice AI.
Troubleshooting Custom Variable Issues in GoHighLevel
When variables fail to populate correctly in a Voice AI call, it is usually tied to configuration details. Use the checks below to diagnose issues quickly.
Confirm the Variable Is Supported
Not every field or entity is supported in Voice AI prompts. If a variable is not documented as supported, it may not resolve. Review the official guide here: Voice AI Custom Variable Support in Prompt.
Verify Contact Data in GoHighLevel
If the syntax is correct but the spoken output is blank or incorrect:
- Open the specific contact record.
- Confirm that the field referenced by the variable actually contains a value.
- Update the record as needed and retest the call.
Check for Recent Field Changes
Renaming, deleting, or altering fields can break references in your Voice AI prompt. When you modify your data structure:
- Audit any Voice AI configurations that use those fields.
- Update the variable names in prompts, summaries, and dispositions.
- Run fresh tests to confirm the changes work correctly.
Next Steps for Optimizing GoHighLevel Voice AI
Once your custom variables are working reliably, you can iterate on prompt design to improve outcomes such as booking rates, qualification quality, and call length. Regularly review call recordings, summaries, and dispositions to align your Voice AI behavior with business goals.
