Update Inventory Price

Hi @amz-tools, Thanks for this library, it’s really useful and good job!

I want to update the inventory price. I tried 4 different ways but neither worked. Am I missing something?

I’m working in the European zone.

Option 1

listingsItems.patchListingsItem request

 .callAPI({
      operation: 'listingsItems.patchListingsItem',
      path: { sku:[sku], sellerId:[sellerId] },
      query: { marketplaceIds: [marketPlaceId], issueLocale: 'en_US' },
      body: { productType: 'PRODUCT', patches: [{ op: 'replace', path: '/attributes/item-price', value: 19.99 }] },
    })

response

code:'InternalFailure'
details:''
message:'We encountered an internal error. Please try again.'
type:'error'

My opinion: I think this endpoint has not been implemented yet for Europe.

Option 2

JSON_LISTINGS_FEED

  const feedType = 'JSON_LISTINGS_FEED';
  const content = {
    header: {
      sellerId: aspConfig.sellerId,
      version: '2.0',
      issueLocale: 'en_US',
    },
    messages: [
      {
        messageId: 1,
        sku: sku,
        operationType: 'PATCH',
        productType: 'PRODUCT',
        patches: [{ op: 'replace', path: '/attributes/listing-price', value: [{ value: price }] }],
      },
    ],
  };

  const contentType = 'application/json; charset=UTF-8';
  const feedUploadDetails = await spService.callAPI({ operation: 'feeds.createFeedDocument', body: { contentType } });

  await spService
    .upload(feedUploadDetails, JSON.stringify(content), contentType)
    .then(res => console.log(res))
    .catch(err => console.log(err));

  const inputFeedDocumentId = feedUploadDetails.feedDocumentId;

  return spService
    .callAPI({
      operation: 'feeds.createFeed',
      body: { feedType, marketplaceIds: [marketPlace.id], inputFeedDocumentId },
    })
    .then(res => console.log(res))
    .catch(err => console.log(err));

The feed document was uploaded successfully and also the feed was created successfully, but the status of the feed is IN_PROGRESS for 12 hours.

createdTime:'2021-07-16T07:42:27+00:00'
feedId:'138122018824'
feedType:'JSON_LISTINGS_FEED'
marketplaceIds:(1) ['A1PA6795UKMFR9']
processingStartTime:'2021-07-16T07:42:35+00:00'
processingStatus:'IN_PROGRESS'

My opinion: I think this feed is related to listingsItems.patchListingsItem at the backend so may has the same problem.

Option 3 & Option 4

feeds: POST_FLAT_FILE_INVLOADER_DATA & POST_FLAT_FILE_PRICEANDQUANTITYONLY_UPDATE_DATA

  const feedType = 'POST_FLAT_FILE_INVLOADER_DATA'; // or 'POST_FLAT_FILE_PRICEANDQUANTITYONLY_UPDATE_DATA'
  const content = `sku price\n${sku} ${price}`;

  const contentType = 'text/tab-separated-values; charset=UTF-8';

  const feedUploadDetails = await spService.callAPI({ operation: 'feeds.createFeedDocument', body: { contentType } });

  await spService
    .upload(feedUploadDetails, content, contentType)
    .then(res => console.log(res))
    .catch(err => console.log(err));

  const inputFeedDocumentId = feedUploadDetails.feedDocumentId;

  await spService
    .callAPI({
      operation: 'feeds.createFeed',
      body: { feedType, marketplaceIds: [marketPlace.id], inputFeedDocumentId },
    })
    .then(res => console.log(res))
    .catch(err => console.log(err));

feeds status:

{  createdTime:'2021-07-17T19:12:48+00:00'
   feedId:'139649018825'
   feedType:'POST_FLAT_FILE_INVLOADER_DATA' 
   marketplaceIds:(1) ['A1PA6795UKMFR9']
   processingStatus:'IN_QUEUE'
}
{
   createdTime:'2021-07-17T16:52:53+00:00'
   feedId:'139397018825'
   feedType:'POST_FLAT_FILE_PRICEANDQUANTITYONLY_UPDATE_DATA'  
   marketplaceIds:(1) ['A1PA6795UKMFR9']
   processingStatus:'IN_QUEUE'
}

I think I’m going to lose the remaining half of my hair because of seller-partner-api and it’s documentation.

Thanks for your help
