My goal is to download all attachments of a given Case. I was managed to perform the needed queries to and I have a pointer to the ContentVersion object I need.

They problem is that I don't know how to download the attachment. I believe I need the VersionData field, which holds the file in binary format.

Another limitation that I have is that I'm using a Linux environment by means of its CLI prompt. I already made an authentication to SF by using SFDX API provided by SalesForce, but I cannot find a way to combine SFDX API with REST API's GET command to fetch the needed file so it will be downloaded to my Linux machine.

Please advise.

Why don't you try curl to retrieve attachments.

As you already have the ContentVersion Id you can fetch VersionData and FileExtension by an SOQL and then can simply run a curl command

curl <your_instance_url>/ContentVersionData -H "Authorization : Bearer {access_token}" -o nameOfFile

  • instead of getting the needed file, I'm getting a small text file with the following data in it – Uri Maslovsky Aug 18 at 8:58
  • var url = window.location.pathname + window.location.hash; if(window.location.search && window.location.search.length > 1){ url += window.location.search; // #189617 } var loc = 'https://*********.salesforce.com?ec=302&startURL='+encodeURIComponent(url); window.location = loc; </script> – Uri Maslovsky Aug 18 at 9:00

  • Not sure where this get wrong but I was able to download file successfully. Might be an issue with filename. it should be name.fileExtension – Pmanglani Aug 18 at 9:47
