Via the CAST Extend Offline API and curl

CAST Extend has a built in API that can be accessed in a manner of ways. It is therefore possible to upload a new bundle using the API, for example with curl:

curl -F "data=@<path_to_file.extarchive>" http://<server>:<port>/api/update

curl option -FThis causes curl to POST data using the Content-Type multipart/form-data. See
<path_to_file.extarchive>The path to the .extarchive bundle file.

Form part of the URL to your on premises CAST Extend Offline. For example:

  • <server>: the local server on which CAST Extend Offline is installed.
  • <port>: the port number which CAST Extend Offline runs on. This is determined during the installation (default port number is set to 8085).

For example:

curl -F "data=@D:\downloads\b2b430df976c412ca29e799fff0fd86e.extarchive" http://cast_extend:8085/api/update
