Reference GHL contact fields in AI conversations
Use GHL contact custom field values in your AI agent prompts to personalize conversations with caller-specific data.
Your AI agent can access contact field values synced from GHL and use them during live conversations. This lets the agent reference a caller’s membership status, preferred location, or any other custom field without the caller repeating themselves.
Set up custom field references
- Identify field names in GHL
In your GHL dashboard, go to Settings > Custom Fields and note the exact field names you want to reference (e.g.,
membership_tier,preferred_location). - Enable Update User Details
Open your agent in the Agent Builder. In the Tools & Abilities tab, enable update_user_details. This tool allows the agent to read and write contact field values during conversations.
- Reference fields in your prompt
Add merge fields to personalize the conversation. For example, reference
contact.first_nameto greet by name,contact.membership_tierto acknowledge their status, andcontact.preferred_locationto suggest their usual branch. - Handle missing values
IF FIELDS ARE MISSING: - If no membership_tier: don't mention membership - If no preferred_location: ask "Which location works best for you?" Never say "I don't have that on file" — just skip the personalization. - Test in Voice Lab
Test with contacts that have custom fields populated. Verify the agent references data naturally and handles missing values gracefully.
