JavaScript Object Notation (JSON)
A lightweight, text-based, language-independent format for exchanging structured data.
JSON is a common contract between APIs, applications, automation platforms and data pipelines, making consistent validation and versioning important for reliable integrations.
A CRM webhook sends a JSON object containing an event type, timestamp and customer identifier; the receiving service validates it against a schema before processing.
JSON has no built-in comments, schema, date type or binary type. Duplicate object names and large numeric values can create interoperability problems, and parsing untrusted input requires size and security controls.
JSON represents values as objects, arrays, strings, numbers, booleans or null according to a defined grammar. RFC 8259 specifies the interoperable format and registers the application/json media type; object member names are strings and ordering should not be relied upon for meaning.
