 # Northwind API
+## Swagger URL
+https://data-northwind.indigo.design/swagger/index.html 
+
+## Highlights
+- Textbook REST example.
+- POST accepts the whole entity, even the "id", although it gets ignored and returns the created entity
+- PUT accepts the whole entity, even the "id"
+- DELETE methods need to map the id, like id=customerId
+- DELETE methods return a copy of the deleted entity
+- In order to create a Bearer token, use the POST -> `/Auth/Register` with the example request body:
+```
+{
+  "email": "[email protected]",
+  "password": "test",
+  "confirmedPassword": "test"
+}
+```
+
+This will return a token in the format:
+
