but I need more detailed docs about api endpoints which I coudn't find out yet. Is there magento have detailed docs about REST API ?
where to find Magento 2 API docs?
Magento Commerce for B2B Generate a local REST API reference
However, the REST API documentation on devdocs is static in that
the Magento Developers website is not running an instance of
Magento, and there is no live data.
http://magento_host/swagger
By default, Magento returns documentation for resources available to
anonymous users. If you specify a valid value in the api_key text box
in the upper right corner, Swagger returns documentation for all the
APIs the user has access to. To generate an API key, call the POST
/V1/integration/customer/token or POST /V1/integration/admin/token as
directed in Token-based authentication.
The generated Swagger documentation provides the capability to test
REST API requests. A user can enter a sample request, then press the
Try it out! button, and Swagger returns information such as a curl
command, a request URL, a response body, a response code, and the
response header. The Try it out! button will not work unless a bearer
authorization token has been specified.
