Recommendation Callbacks
The JS API can be used to register callbacks to hook into the recommendation events. To register a listener for a callback, use
api.listen(callbackId, callbackFunction) function.Called when Nosto has responded and finished recommendation placement.
nostojs(function(api) {
api.listen('postrender', function(event) {
console.log(event.filledElements);
console.log(event.unFilledElements);
});
});
Field | Type | Reason |
|---|---|---|
filledElements | Array | Contains a list of recommendation slots that contain recommendations |
unFilledElements | Array | Contains a list of recommendations slots that did not have get recommendations. |
Called when Nosto has responded but not yet rendered content. The event contains information about the visitor's preferences.
nostojs(function(api) {
api.listen('prerender', function(event) {
console.log(event);
});
});
Field | Type | Reason |
|---|---|---|
affinityScores | Object | Describes visitor's most preferred brands and categories, the object has two attributes top_brands and top_categories which are arrays that contain maximum 5 most preferred brands/categories for the visitor. Example content: {top_brands:[{name:"Acme", score:0.8},{name:"Universal", score:0.3}]} |
segments | Object | Information about which segments the visitor falls into. active_segments field contains a list of segment identifiers that were active on the latest request to Nosto. Segment identifiers can be retrieved from the Nosto backend, or queried from the GraphQL API.
Example content: {active_segments:[{id:"5a497a000000000000000004"},{id:"5aa12b8960b2352d326d77f1"}]} |
