Manage GoHighLevel Contacts and Invoices with AI Assistant

Windsor’s GoHighLevel connector can create and update CRM records, not just report on them. Once connected, ChatGPT, Claude, or Copilot can create a contact, update an existing one, and draft an invoice, all from a chat, with the exact change shown to you before it saves.

What you can do

• Create a contact. At least one of first name, last name, name, email, or phone; company, address, website, timezone, source, and tags are optional. GoHighLevel deduplicates on email or phone within the location, so a matching contact may get updated instead of a new one being created.
• Update a contact. By id, only the fields you provide are changed. Tags replace the contact’s existing tags rather than adding to them.
• Create an invoice. A draft invoice for an existing contact, with a business name, currency, issue and due dates, and at least one line item. It’s created as a draft, not sent, sending happens from the GoHighLevel UI.

Prompts worth running

Add a new contact: Jane Doe, [email protected], tag her "webinar-lead".

This contact's phone number changed, update it on contact [id] to
+1 555 0100.

Draft an invoice for contact [id]: $1,500 for "Q3 consulting",
due in 30 days.

If your first attempt fails, it’s almost always one thing

Updating an existing contact succeeds close to every time it’s tried. Creating a new contact fails more often than that, and in practice nearly every failure, on both actions, comes back as the same error: the connected GoHighLevel account hasn’t granted the contacts.write permission this action needs. If the account was connected before this write action existed, that permission was never requested in the first place.

The fix is the same one as most permission errors: reconnect the account in Windsor.ai. That re-authorization is what grants contacts.write, and it clears the error on the next attempt, no code change or support ticket required.

The one other real failure cause worth knowing: GoHighLevel rejects a new contact outright if it has none of email, phone, first name, or last name, at least one is required, a name alone written as a single “name” field doesn’t substitute for it.

You’re always in control

Your assistant shows you the exact contact fields or invoice details before anything saves. Nothing is created or changed without your confirmation, and the list of actions available to it is pulled live from Windsor’s API, so it always reflects what your connected account can currently do.
