MWS SubmitFeed (Amazon Marketplace Web Service)

See more HTTP Misc Examples

Uploads a feed for processing by Amazon MWS.

See Amazon MWS SubmitFeed for the Amazon MWS SubmitFeed reference documentation.

Important: The Chilkat v9.5.0.75 release accidentally breaks Amazon MWS (not AWS) authentication. If you need MWS with 9.5.0.75, send email to support@chilkatsoft.com for a hotfix, or revert back to v9.5.0.73, or update to a version after 9.5.0.75.
