This topic is about an API for on-premise use. To learn about Fiftytwo cloud-based APIs, go to https://api.fiftytwo.com/.
52API BASKET, commonly known as Basket API, is a REST interface over HTTP(S) that uses either XML or JSON as input and output format
It provides basket and receipt calculation optimized for web and scalability, and makes discounts, etc. work exactly like they do with a regular till.
Key characteristics of Basket API:
-
Exposed as a stateless REST interface
-
No persistence of basket or receipt
-
Possible to run multiple 52ViKING tills, which allows load balancing and scalability
-
Each 52ViKING till has a single import of articles and a single database, but multiple execution threads
-
Useful as a basis for automated test and verification of correct calculations
Basket API is used with retail systems like 52ViKING.
HTTP return codes
Basket API uses these HTTP status codes as return codes:
-
200 OK
On GET request with a successful reply.
On POST request with a successful reply.
-
204 No Content
Default return code for POST request with no reply data.
-
400 Bad Request
Returned if request is wrong or if request is missing information.
-
404 Not Found
Returned if request fails, for example because of missing content.
-
50x Internal Server Error
Returned when a server-side error occurs, for example because of a missing instance or a wrong server-side configuration.
Supported encoding
-
UTF-8
CalculateBasket
CalculateBasket is called whenever a receipt is to be calculated. The logic used to calculate the basket is controlled by 52ViKING.
All discounts are applied to articles that are eligible for discount.
Receipts are line-orientated, so an article/line can hold one or more single articles. Articles can be sold either one-by-one or by using quantity. Regardless of which method is used, the lines (articles) are neither collapsed nor expanded.
Example: An article sold with a quantity of 1 followed by a quantity of 2 will be replied as an article with quantity=1 AND another article with quantity=2. In order to combine these articles, the request must hold the article with quantity=3. If a request for expansion is made, the request must hold the article three times (all with quantity=1).
The same applies to discounts: They're neither combined nor expanded, but always applied (calculated) with the number of articles for the current article in mind.
Amount is a regular number that always has 2 decimals.
CalculateBasket input is defined in basketinput.xsd (XML) and basketinput.json (JSON) respectively.
CalculateBasket output is defined in basketoutput.xsd (XML) and basketoutput.json (JSON) respectively.
The .xsd and .json files are provided separately.
When the API refers to coupons in the following, it means vouchers. See also Voucher API.
