Way to identify consecutive orders without personal data (restricted by RDT) ?

[frankbirzle]

Hi there,

is there a way via SP-API to tell whether an order was made by a certain customer in order to identify whether it was the customer's 1st, 2nd, Nth order?

Apart from that info we don't really need access to the restricted endpoints but saw that even the anonymized (@marketplace.amazon.de) buyerEmail is part of the data to be deprecated past January 12, 2022.

Thanks for your help!
