Documentation to JSON_LISTINGS_FEED

[KemnaMOL]

Problem description:

Hello,
I can´t find a documentation who I can upload data with the newer JSON_LISTINGS_FEED.
At the moment I use the older XML-version.

I don´t want to use the new Transformer.

There's pretty thorough documentation on migrating to the Listings API (the JSON_LISTINGS_FEED is basically just a wrapper for sending many Listings API requests at the same time) here. Once you've built the feed contents, the process is the same as submitting any other feed type, which is documented in the README, here.

Out of curiosity, what's holding you back from using the feed transformer?

[KemnaMOL]

Many thanks.
I think it´s easyer to give the right data, than installing a new tool. Also I can mix price and stock data at one time.
Best regards, René

Your documentation is only for XML-files. What I have to change?
feedType to JSON_LISTINGS_FEED and at feedContents the JSON-file is enough?

[jlevers]

Yeah, all you need to do is change the feed type and the library will handle the rest.

[KemnaMOL]

Yeah, I got it in this way.
But nothing changed. Now I will try to read the feed status and answer.

Check out this https://developer-docs.amazon.com/sp-api/docs/listings-management-workflow-migration

Also you can use this to get JSON feed schema

$schema = $definitionsApi->getDefinitionsProductType($type, [ $marketplace->getId() ], $sellerId, locale: 'en_US'); > $meta = $schema->getSchema()->getLink()->getResource();

base $type is "PRODUCT"

Here are some examples + a place where to ask questions

Also note that JSON has way harsher restrictions on feed file size and message count - aside from format conversion we also had to implement way to generate the feed into multiple files + internal queue that is sending the files one by one with some delay (and retry)

If you have a question feel free to contact me @KemnaMOL

Hi @NoxArt - mind me getting in touch? I am really struggling to understand the process of converting what I had for sending stock over to the JSON method etc. I've spent weeks now reading 'snippets' of code but I need a full overview realistically. See my latest issue thread for example: #829

Happy to discuss over email or other means if easier.

Yeah, I got it in this way. But nothing changed. Now I will try to read the feed status and answer.

@KemnaMOL - I am providing my completed code here for when I finish getting JSON working too. What I have currently would work to send JSON too, I just need to find out which format for my use case.
