The Analytics API retrieves call-limit data and the quotas that are set for the RESTful APIs and their associated resources. Responses from calls made to getRateLimits and getUerRateLimits include a list of the applicable resources and the "call limit", or quota, that is set for each resource. In addition to quota information, the response also includes the number of remaining calls available before the limit is reached, the time remaining before the quota resets, and the length of the "time window" to which the quota applies. The getRateLimits and getUserRateLimits methods retrieve call-limit information for either an application or user, respectively, and each method must be called with an appropriate OAuth token. That is, getRateLimites requires an access token generated with a client credentials grant and getUserRateLimites requires requires an access token generated with an authorization code grant. For more information, see OAuth tokens. Users can analyze the response data to see whether or not a limit might be reached, and from that determine if any action needs to be taken (such as programmatically throttling their request rate). For more on call limits, see Compatible Application Check.

Please make sure you use the correct version of the APIs for your use case. To find out the appropriate version, go to the API Docs drop down on the menu.

A product library is a representation of all the items that can be
displayed, put in a shopping cart and sold to a customer. Items may be
either producs or discounts.
A product is a synthetic construct, wrapping one or more variants (which is
the actual item being sold) Variants expresses different variations of
properties such as for example price, size or color. A discount will reduce
the total amount charged in a shopping cart. It can be used per item line,
or on the whole cart. It may reduce the affected amount by a percentage, or
by a fixed amount.
Together, the above types of entities makes up a complete library. The
library can be fetched as a whole through the library endpoint, where each
consecutive change applied to the library is available. Once the full
library is retrieved, only later events needs to be fetched to keep the
client up to date with the server
All path patterns "/organizations/{organizationUuid}/" can be replaced
with "/organizations/self/" for convenience as all endpoints are for
authorized users.
