Getting Started


The endpoint and body of the Cancel Order Package Item Service is updated. Until August 31, 2021, the old and new service will be active together. After August 31, the old service will be closed for use. You need to revise your systems to work with the new service.

13-digit cargo tracking numbers starting with "7" belonging to Trendyol deliveries are generated from our barcode pool with a certain rule and sent to the cargo company at the time of delivery. In August, the number of digits will be increased in cargo tracking numbers and will be created as 16 digits.

Our new accounting service is live. To review, you can browse the accounting integration section.
