# How the Sendcloud APIs work

Sendcloud APIs are **RESTful** and communicate over HTTPS using standard HTTP methods:

* `GET` to retrieve data
* `POST` to create resources
* `PATCH` or `PUT` to update resources
* Action endpoints (for example, cancel or announce)

Requests and responses use JSON unless stated otherwise.

You can integrate using:

* your own backend or HTTP client
* [cURL](https://curl.se/)
* API tools such as [Postman](https://www.postman.com/) or [Bruno](https://www.usebruno.com/)

Sendcloud does not require SDKs — you're free to use whatever language or framework you prefer.
