JSON

Overview

JSON is a lightweight text format for exchanging structured data using objects, arrays, strings, numbers, booleans, and null values. JSON is a text data-interchange syntax and does not by itself supply a schema, versioning policy, signature, encryption, type precision, or business semantics. Different parsers may treat large numbers, repeated keys, invalid Unicode, or top-level values differently, creating interoperability or security problems. Monitoring for JSON should distinguish transport success, processing success, and the final external or financial result.

Data modeling for JSON should use stable identifiers, explicit timestamps and timezones, documented decimal and currency rules, nullable-field semantics, enumerated statuses, and immutable historical references. JSON syntax does not define a business schema, numeric precision policy, date type, comments, or duplicate-member handling. Its media type is commonly application/json, and UTF-8 is the standard encoding for interoperable exchange. Parsers should reject malformed input, bound nesting and size, and avoid unsafe object mapping.

For JSON, developers should retain one correlation path across these stages because an immediate response can differ from later provider, blockchain, payment, accounting, or settlement state. JavaScript Object Notation represents structured values in a language-independent textual syntax. Objects contain name-value members, arrays contain ordered values, and values can nest. APIs should define schemas, limits, required members, null behavior, numeric ranges, and canonical forms when signing or hashing. For JSON, identifiers and timestamps should remain stable enough to trace the technical action to its final business outcome.

Logs must not expose credentials or sensitive payload fields.

Changes to JSON should be tested against normal, failed, delayed, duplicate, and recovery paths that apply to the operation.
