Move files from one folder to another using Google Drive API and Apex [closed]

Question

I’m making a callout using named credentials and trying to update the parent Id of the G-Drive file. While doing the callout, getting the below error.

"error": { "errors": [ { "domain": "global", "reason": "cannotAddParent", "message": "Increasing the number of parents is not allowed" } ], "code": 403, "message": "Increasing the number of parents is not allowed" } }

And here is the apex restapi callout to change the parent id of the file.

Http http = new Http();

HTTPResponse response;
HttpRequest request;
String folderId = '1iXXXXXXXXXXXXXXXXXXXXXXXXXXX'; // G-Suite folder id
String body = '{"id": "'+folderId+'"}';   

// Initialize the request Instance
request = new HttpRequest();
request.setMethod('POST');
request.setHeader('content-type', 'application/json');
request.setEndpoint('callout:XXXXXXCloudGDrive'+'/'+fileId+'/parents'); // named cred 
request.setBody(body);

response = http.send(request); 

Any Idea on How to update the parent id(folder Id) of a GDrive File using Apex callout?

On the documentation, they provide a method to remove parent of the file from the current folder. How can we achieve this in Apex ? https://developers.google.com/drive/api/v3/multi-parenting

Answer 1

According to an error message, the very first sentence of Google Drive API Guide says:

Beginning Sept. 30, 2020, you will no longer be able to place a file in multiple parent folders; every file must have exactly one parent folder location. Instead, you can use a combination of status checks and a new shortcut implementation to accomplish file-related operations.

I can assume that an error is related to this, and has nothing to do with Apex itself.
