JSON

noun · also: api, json-path, webhook

What is json?

JSON (JavaScript Object Notation) is the data format almost every modern API uses to send and receive structured data.

Definition

Full definition of json

JSON looks like {"name": "Sarah", "age": 30, "emails": ["sarah@example.com"]}. It's a human-readable, machine-parseable format that became the de-facto standard for web APIs in the 2010s. Every Tiny Command action receives JSON from upstream steps and produces JSON for downstream steps. Knowing how to read JSON is the single highest-leverage skill for automation work.

FAQ

Common questions about json

How do I extract a field from JSON?
Use dot notation: response.data.object.amount. Tiny Command's field picker shows you the available paths visually.
What if a field is sometimes missing?
Use a default: response.amount ?? 0. Or add a Filter step earlier to skip records without the field.
