Hi @carlosdavid-textilesmontecid,

it seems you forgot to upload and create the feed. Once you have called the createFeedDocument operation you next step would be calling the .upload() function, like this:
let res = await sellingPartner.upload(feed_upload_details, feed);

Then you have to call the createFeed operation, see the docs here. Only then the feed processing is triggered. You can then use the returned feedId to see the status of the processing with the getFeed operation and once it has the status DONE, you can use the resultFeedDocumentId as input for the getFeedDocument operation, which then returns the download details that you can then use as input to finally call the .download() function, that returns you the result of the uploaded feed.

Quite complicated with a chain of calls there, thats why we already have the plan to add something like a feed() function to the client that wraps up all these necessary calls in one function. It will be part of one of the next client releases but no time frame for that yet.

Hi @amz-tools !

Yes, I was trying to do the whole process but I haven't been returning anything with the .download() function, I thought it was because of the signature error that I was receiving.
As you told me to continue the process, I focused instead on the function (with the debugger tool I could be able to get the body of the response after decrypted) and found that I haven't been declaring the file where I wanted the result.
Now I can see the content of the response.

Thank you very much for the detailed answer, and of course, for the whole library!
