3 years ago I'm using this Feed Type and a few weeks ago it was fixed and is now fully working. The process is as follows:
- Get URL and encryption details for upload using the createFeedDocument method. You must put "contentType": "application/pdf" in the body of the request.
- Encrypt the invoice using AES-CBC with the encryption key and IV received in first step
- Upload invoice to the URL received in the first step using a simple PUT request. You must put "Content-Type": "application/pdf" in the headers
- Create the feed using the "createFeed" method with the following body:
{ feedType: "UPLOAD_VAT_INVOICE", marketplaceIds: [MARKETPLACEID_OF_ORDER], inputFeedDocumentId: documentId, // received in first step feedOptions: { "metadata:invoicenumber": INVOICE_NUMBER, "metadata:orderid": AMAZON_ORDER_ID // optional! "metadata:totalamount": INVOICE_AMOUNT "metadata:totalvatamount": INVOICE_VAT_AMOUNT } }You will received the FeedID, which you ca use to track if everything worked. As this was not asked in this issue, I won't explain this but here is the code i used in NodeJS usning my own SDK:
const FeedStatus = await amzSDK.request({
account,
region: "eu",
type: "getFeed",
data: "50653018715",//feedRes[0].feedId,
accessToken: mwsAccountConfig.accessToken,
iamUserAuth: auth,
bottleneckConfig: {
...auth.redisAuth
}
})
console.log(FeedStatus)
const FeedDocument = await amzSDK.request({
account,
region: "eu",
type: "getFeedDocument",
data: FeedStatus[0].resultFeedDocumentId,
accessToken: mwsAccountConfig.accessToken,
iamUserAuth: auth,
bottleneckConfig: {
...auth.redisAuth
}
})
const FeedDocumentEncryption = {
iv: Buffer.from(FeedDocument[0].encryptionDetails.initializationVector, 'base64'),
key: Buffer.from(FeedDocument[0].encryptionDetails.key, 'base64'),
url: FeedDocument[0].url
}
const FeedDocumentFile = await axios.get(FeedDocumentEncryption.url, {responseType: 'arraybuffer'}).then(r => Buffer.from(r.data, "binary"));
const decryptedFile = await aes.decrypt(FeedDocumentFile, FeedDocumentEncryption.key, {name: 'AES-CBC', iv: FeedDocumentEncryption.iv});
console.log(Utf8ArrayToStr(decryptedFile))

We need the documentation for UPLOAD_VAT_INVOICE because we need to automatically upload invoices via the Feed API. There is no clear statement if we can upload multiple invoices and credit notes on a specific order with multiple order items.
Here is the link to pdf documentation that states that this FeedType exists. https://m.media-amazon.com/images/G/03/B2B/invoice-uploader-developer-documentation.pdf
Thank you, if someone tested this FeedType please let us know how it goes.
