API

The API responds with JSON code depending on an HTTP Get request.

Note: These were all tested using a simple manual test. The function themselves are not complex enough to warrant an automated test of each function.

All Products Fetch

• Description: This feature will return a JSON containing all products currently in stock (inventory_count is greater than 0).
• Get request: api/v1/products
• Response 200 (OK):

  • body: JSON of all products (List of dictionaries with correct data types).
