Let me guess: You cracked open HighLevel’s API docs …and 30 seconds later, you felt like tossing your laptop into a volcano. 🌋
You’re not alone.
In a recent Zoom session, Mario Aldayuz (Head of Partnership at HL Pro Tools) unpacked how to actually make HighLevel APIs work for you—even when the docs are vague, incomplete, or just plain confusing.
He also showed how pairing HighLevel with N8N turns clunky integrations into smooth, scalable workflows. Let’s break down the highlights.
HighLevel APIs: Powerful but… “quirky”
Don’t get me wrong—HighLevel’s API gives you crazy potential. But here’s the truth most devs learn the hard way:
🧠 The docs are often incomplete, outdated, or straight-up missing info.
So if you’re trying to programmatically trigger automations, build custom email templates, or pass dynamic data between subaccounts… You’re probably hitting roadblocks.
What To Do When the API Isn’t Cooperating
This is where Mario’s advice came in clutch.
Here’s how to troubleshoot and win even when the docs fall short:
✅ Use N8N’s HTTP Request module
Forget waiting for official integrations—just hit the raw endpoints directly.
✅ Test. Break. Repeat.
Seriously, try stuff. Reverse engineer it. See what the payload returns and tweak from there.
✅ Use Postman
It’s like Google Translate for APIs. Simulate requests, see what works, and spot undocumented quirks.
✅ Don’t be afraid to annoy support (nicely)
Some of the best info comes from back-and-forths with the HighLevel team. They’ll often confirm features that aren’t even in the docs yet.
Key Idea: *You can still build scalable, repeatable automations—*you just might have to DIY your way through it.
Turning API Limitations Into Innovation
Here’s the mindset shift that changed everything for me:
APIs aren’t just tools—they’re opportunities to build smarter systems.
Most agencies see API gaps as “stoppers.” I see them as a challenge to innovate.
💡 Can’t find a clean way to send emails via the API? Cool—let’s build a custom Markdown-to-HTML email generator using N8N and OpenAI.
💡 Subaccounts behaving inconsistently? Sweet—we’ll drop in a Google Sheet as a routing layer.
The beauty of N8N is that you don’t need every API to be perfect—you just need a little creativity and a handful of tools that play well together.
Final Thoughts
If you’re deep in the HighLevel ecosystem like I am, here’s your new motto:
“The API is weird, but I’m weirder.”
N8N gives you the power to turn chaos into clarity.
- You don’t need Zapier-level pricing.
- You don’t need every endpoint mapped out.
- You just need the right workflows and a little grit.
