OCAPI Flash

Flash is a property of documents and contains special information about the document.

Such information could be:

• a message that the basket contains a product that is no more available.
• a message that the basket contains a product that has no price.
• … and so on.

It’s currently only used at the basket document. The presence of a flash indicates a reason why the basket can’t yet be submitted. See examples of basket resource.

In the Scripting API, flashes can be read from, added to or removed from a document using the methods addFlash, removeFlash, and flashes or getFlashes(). Flashes can be added to any object within the structure of the document - for example a flash may be added to the baskets billing address with the path $.post_code or to one of the baskets product items with path $.adjusted_price. Before sending the response to the client, such flashes are aggregated to the document and their paths are adjusted appropriately, in our example to $.billing_address.post_code and $.product_items[0].adjusted_price.

Example usage showing addition, listing, and removal of flashes:

1exports.validateBasket = function(basketResponse) {
2     basketResponse.addFlash({
3       type: "MyType",
4       message: "My message",
5       path: "my_path",
6       details: {
7           "k1": "v1",
8           "k2": "v2"
9       }
10    });
11    var flashToRemove;
12    for each(f in basketResponse.flashes) {
13      if (f.type == "SomeOtherType") {
14        flashToRemove = f;
15      }
16    }
17    if (flashToRemove != null) {
18       basketResponse.removeFlash(flashToRemove);
19    }
