S3 List Parts

GET https://s3.{{region}}.backblazeb2.com/:bucket/:key?uploadId=

Lists parts that have been uploaded for a given multipart upload.

By default, sets of up to 1,000 results are returned. You can set max-parts to set the maximum result set size to less than 1,000. If the search results number more than the maximum result set size, then the first set is returned in the initial response, the response element contains the value true and the element contains a token to retrieve the next set of results. Use this token as the part-number-marker query parameter in another request to retrieve the next set of results.
