Upload file chunks (Resumable Step 2)

Upload file chunks (Resumable Step 2)

Uploads a piece of the file. The maximum size of one chunk is 10 MB. Chunks are uploaded sequentially until the entire file is transferred.

Samples:

Uploading the first chunk:

curl --location -g --request PUT 'https://{portal-url}/api/v2/storage/file.zip?format=resumable' \
--header 'Content-Range: bytes 0-10485759/52428800' \
--data-binary @chunk1.bin

Uploading the last chunk:

curl --location -g --request PUT 'https://{portal-url}/api/v2/storage/file.zip?format=resumable' \
--header 'Content-Range: bytes 41943040-52428799/52428800' \
--data-binary @last_chunk.bin
