A Recommend request is triggered when a Recommend API call is performed to retrieve a list of recommendations for a specific item.

Multiple Recommend requests can be batched within a single Recommend API call to improve network latency. However, your usage will be calculated based on the amount of recommend requests that are batched within each call.

For example:

Every time you request recommendations for a given objectID that counts as a chargeable request. This is regardless of how those requests are bundled into API calls:

• 5 x API calls, each for a single objectID = 5 chargeable requests.
• 1 x API call, containing 5 requests for recommendations = 5 chargeable requests.
