API
An API (Application Programming Interface) is a programmatic interface that lets systems communicate with each other. StoreChart provides a native API that gives access to orders, inventory, customers, and more — for custom integrations and automations.
An API (Application Programming Interface) is an interface that lets different software systems communicate and exchange data, typically through standard HTTP requests (GET, POST, PUT, DELETE) that return a response in JSON format. Instead of every system speaking a different language, the API defines a clear contract: what data can be requested, in what format, and what permissions are required. eCommerce businesses use APIs to connect their store to external tools — an accounting system, a marketing platform, or a custom mobile app — without manually re-entering data. StoreChart provides a full API with access to orders, inventory, customers, and profitability, secured with token-based authentication, caching for fast performance, and rate limiting that prevents server overload. The API also connects to automation platforms like Make.com and Zapier, so you can build automated workflows — for example, automatically sending a WhatsApp message whenever an order's status changes — without writing any code.
API design quality matters as much as API existence: a well-designed API is versioned (so existing integrations don't silently break when the API changes), documented with real request and response examples, and rate-limited transparently so integrators know their operating limits in advance rather than discovering them through failed requests. A store evaluating any platform's API should check specifically whether it exposes the data that actually matters for automation — orders, inventory, and customers — rather than only superficial account settings.
Every automated connection StoreChart maintains — the WooCommerce sync, payment webhooks, the WhatsApp Business channel — happens through an API contract on one side or the other, which is exactly why a small unannounced change to that contract on a third-party's end can quietly break a sync that was working fine the day before. This is also why the platform's own public API is documented and versioned rather than left informal: any external tool integrating against it needs the same stability guarantee StoreChart itself depends on when connecting to WooCommerce or a payment provider.
A well-designed API includes versioning from the start, precisely so a breaking change can be introduced as a new version while existing integrations keep working against the old one — skipping this discipline early is a common reason platforms end up unable to change anything without breaking every connected integration at once.
Frequently asked questions
An API is typically pull-based — your system requests data when it needs it. A webhook is push-based — the other system sends data the moment an event happens. Most real integrations use both: an API to fetch or write data on demand, and webhooks to react to changes instantly.
Direct API usage requires coding or a developer, but the same API often powers no-code automation platforms (like Make.com or Zapier) that let non-developers build workflows through a visual interface without writing requests by hand.
It's a cap on how many requests a given API key can make in a time window (for example, 100 requests per minute), designed to prevent one integration from overloading the server for everyone else. Exceeding the limit typically returns an error response until the window resets.
