The scope of historical data varies from integration to integration. In most cases Greenback can acquire multiple years of historical data. There are a few known exceptions to this listed below.
eBay only stores your data for 90 days. However if your eBay transactions were settled using PayPal, Greenback can back-fill summary level transactions going back 3 years. PayPal is limited to summary data as it will lack the specific items sold or purchased. For assistance on acquiring historical eBay data, please contact Greenback support for assistance.
If you need Amazon Seller Central transactions older than 90 days, you will need to specifically request historical statements before Greenback can fetch those transactions.
