How to Write Custom Code with AI in HighLevel

You just landed a massive commercial roofing client. They use a legacy CRM. You need to connect their system to HighLevel. The data transfers over, but the dates are in the wrong format and the phone numbers are a complete mess.

You spend four hours staring at a blank custom code box. You are not a developer. You try copying and pasting JavaScript from a random forum. You hit test. The entire workflow breaks. You are burning profitable hours on a task that should take five seconds.

You do not need to hire an expensive developer just to format a date. HighLevel just dropped AI-Powered Code Generation directly inside your workflows. You can now type exactly what you want in plain English, and the AI will write the perfect JavaScript snippet instantly. Let us turn you into a developer.

Part 1: Open the Coding Assistant

Ready to streamline this? Here is exactly how to do it in 60 seconds:

1. Open your workflow and select the Custom Code action.
2. Click Code with AI to activate the AI-powered coding assistant.

Part 2: Give the AI Instructions

1. Provide a clear description of what you need in plain language. You can ask it to format phone numbers, extract email addresses from subject lines, or perform real-time mathematical calculations for interest rates.
2. Be highly specific with your request. A great prompt looks like “I have an API that returns a date in MM-DD-YYYY format. Convert it to YYYY-MM-DD.” The more specific your prompt, the better the AI-generated code will be.

Part 3: Generate and Deploy

1. Click Generate. The AI will instantly create the necessary JavaScript snippet and automatically map the input properties from your previous workflow steps.
2. Review the generated code. If you need a slightly different version, simply click Generate again for an updated snippet.
3. Examine the final output and click Use Code to insert it perfectly into your workflow.

Writing custom JavaScript used to be a massive technical roadblock, but now your team can deploy advanced API integrations and conditional logic in seconds without writing a single line of code manually.

You can use AI to write flawless custom JavaScript and build the most technically advanced API integrations in the world.

But perfectly formatted backend data does not manufacture trust.

Your workflow might trigger without a single error, but when that prospect is deciding whether to sign a high-ticket contract, a flawless technical setup only gets you so far. They need undeniable proof that your agency actually delivers real results for real businesses. Authentic client testimonials are what truly close the deal.

The massive mistake most agencies make is treating their social proof like broken code. They build incredible backend systems but leave their most powerful client success stories completely scattered across random emails, never turning them into a structured asset.

I am handing you the exact automated machine my team uses to systematically gather, refine, and organize client testimonials so they are ready the exact second your sales team needs them.
