The usage of our Retail3000 API environment is granted as long as fair use is being applied. An important example of fair use is not requesting the same data over and over again. For example requesting all products again and again, instead of using a 'Modified Since DateTime' filter.

Another example of fair use is requesting data at once by using a correct 'Get' statement. So to get all rows of invoices for example, request all rows at once instead of requesting all rows per invoice. In general, the use of 'Get 'statements is much better than using 'GetSingle' statements to get individual records. The use of GetSingle methods in general will result into many separate requests. We prefer requesting a whole number of records at once, instead of requesting the same number of requests in a big number of GetSingle requests.

Our reverse proxy servers log all traffic and calculations of the number of requests and the number of involved KB's will be done. If a certain combination of IP address and Retail300 API token executes too many requests and/or too many KB's, a temporary block of traffic can occur. From the start of 2018, customers will need a license for API integrations. Although the exact terms are not known at this moment, it can be expected that a small amount of API traffic will be free or charge. But larger integrations will need some license in relation to the expected traffic. Even with this license, the fair use of our systems is still applicable.
