I have some data on the ContentVersion object. I want to update the field VersionData in the ContentVersion object using REST API. Here is some more detail about the API.

Endpoint: https://mysite.my.salesforce.com/services/data/v51.0/sobjects/ContentVersion/ID

Payload:

{ "Title": "Update TEST", 
 "ReasonForChange":"Marketing materials updated",
 "PathOnClient" : "Q1 Sales Brochure.pdf", 
"versionData":"[...]" }

Please help me out.

  • By definition, ContentVersion is an instance of each file version so it can't be updated, only created as a new version

As discussed in this SFSE link, It seems ContentVersion can't be updated.

But you can create a new ContentVersion and attach to the same ContentDocument as below with the ContentVersion API.

URL - /services/data/vXX.0/sobjects/ContentVersion

Method - POST

Body :

{
    "ContentDocumentId" : "069.....",
    "PathOnClient" : "sfdclogo.jpg",
    "ReasonForChange" : "New Version",
    "VersionData": "/9j/4AAQSkZJRgABAQAAAQABAAD/4gIcSUNDX1BST0ZJ...//The content or body of the file (Base64 encoded) 
}
