How do I upload a bulk file to Amazon?
Open Bulk operations in the Amazon Ads console for the correct advertiser profile and marketplace. Upload the reviewed file AutoPPC produced, then wait for Amazon to finish processing it.
Inspect Amazon's processing report for rejected rows. An existing keyword, an invalid bid or an archived entity can cause a partial failure. Do not assume the whole batch succeeded merely because the file was accepted.
AutoPPC also checks the expected changes on a later read-only pull. Keep that verification separate from the upload receipt, and do not blindly upload a duplicate file to fix a partial failure.
