Overview

The Save Address custom tool enables your AI assistant to collect a user’s full address (street, city, state, zip code) during a conversation and save it directly to the contact profile in GoHighLevel. This is particularly useful for service businesses that need addresses for appointments, inspections, or deliveries.
Since Version 2.1, Assistable includes a pre-built tool with this functionality. This guide is still useful for learning how to build custom tools from scratch.

Map Address Fields in CRM Workflow

Back in the GoHighLevel automation:
  1. Click Fetch Sample Request to pull sample data
  2. Add a Find Contact action using contact_id from the webhook

    • Street Address → Inbound Webhook > Arguments > street
    • City → Inbound Webhook > Arguments > city
    • State → Inbound Webhook > Arguments > state
    • Postal Code → Inbound Webhook > Arguments > zip_code
  4. Save and publish the workflow

Test and Validate

  1. Run a test conversation with your AI assistant
  2. Provide an address when prompted
  3. Check the contact’s General Info section in GoHighLevel
  4. Verify all address fields are correctly populated
