JSON
also JavaScript Object Notation
A lightweight, text-based data format using key-value pairs and arrays that is the standard way APIs and webhooks exchange structured data.
Analogy
Like a labeled form where every value sits next to its field name, readable by humans and machines.
Why it matters
Nearly every payload, API response, and structured output you handle across GoHighLevel, n8n, Make, and Zapier is JSON.
In practice
{"name":"Allen","tags":["lead","vip"]} representing a contact.
