Backblaze supports external integration through an HTTP-based REST API.\\
__Restriction:__ REST API does not support resume on upload and mdtm(File modification time) changes. You can use the __S3 connection endpoint__ as a workaround.\\
\\
!1. Access through B2 REST API\\
\\
Create App keys on [https://www.backblaze.com/]\\
[attachments|b2_app_key.png]\\ 
\\

\\

The URL pattern looks like this:
{{{
b2://<<KeyId>>:<<applicationKey>>@api.backblazeb2.com/<<Bucket Name>>/
}}}\\
\\

\\

\\
Open the bucket settings and use the s3 endpoint URL for S3 connection.\\
\\
[attachments|b2_s3_endpoint.png]\\
