JSON
Definition
JavaScript Object Notation - a lightweight format for storing and transporting data. Like a universal language for computers to exchange information.
Use Cases
- Stripe: Payment processing APIs exchange transaction data with merchants — Stripe’s REST APIs commonly return and accept JSON payloads (for example, objects representing charges, customers, and payment intents) so client apps and servers can parse and act on the data consistently. (Developers can integrate payments quickly using a predictable, language-agnostic data format, reducing integration time and improving interoperability across platforms.)
- GitHub: Automations and integrations consume repository and issue data — GitHub’s REST API returns resources such as issues, pull requests, and webhooks as JSON, enabling CI/CD tools and custom scripts to read event payloads and trigger workflows. (Ecosystem tools can reliably automate development processes (notifications, deployments, reporting) using a standard structured format.)
- Twilio: Messaging and communications platforms exchange message status and metadata — Twilio APIs commonly use JSON for request/response bodies and webhook event payloads (delivery status, message details), allowing applications to parse updates and update internal systems. (Applications can integrate communications features with consistent machine-readable data, improving reliability of event-driven processing.)
Frequently Asked Questions
- What's the difference between JSON and XML?
- JSON and XML are both formats for structuring data for exchange. JSON is usually more compact and maps naturally to objects and arrays used in many programming languages. XML is more verbose and uses tags; it can be better when you need document-style markup or complex schema tooling, but for most web APIs JSON is the common default.
- When should I use JSON?
- Use JSON when you need a simple, widely supported way to send structured data between systems—especially for web APIs, configuration files, event payloads, and logs. It’s a strong choice when humans may also read or edit the data and when you want broad compatibility across languages and platforms.
- How much does JSON cost?
- JSON itself is free—it’s an open text format. Costs come from the systems that store, transmit, or process JSON (for example, API gateway requests, data egress, database storage, log ingestion, or compute time to parse/validate JSON).
