I'm working on part of an Apex class to store a retrieved binary file using the REST API to a test folder on Salesforce and I'm not sure exactly how it'll work. I have the Salesforce ID of the test folder, but I'm not sure if it'll require an HTTP POST like this one below:

@HttpGet
   public void basicCallout(){
     HttpRequest req = new HttpRequest();
     req.setMethod('GET');
     req.setEndpoint('callout:/thirdpartyapi/<filepath>');
     req.setHeader("Authorization", "Oauth" + loginResult.getAccessToken());
     HTTPResponse res = new Http().send(req);
     res.setMethod('POST');
     res.setEndpoint('https://na1.salesforce.com/<SalesforceFolderID>');
     }

I'm working off the following example as a reference:

Since you're already in Apex Code, you can store the document directly:

Document doc = new Document(Name=..., Body=res.getBodyAsBlob(), FolderId=...);
insert doc;

As a side node, if you did need a second callout, you'd need to create a new HttpRequest, and not modify the HttpResponse res as you've done here.

  • I see. I'll keep that in mind. Out of curiosity, is there any way to preserve the filename and extension when it's transferred over? To my understanding, HTTPRequest/HTTPResponse commands can only transfer the binary data and not anything else. – xorLogic May 24 '18 at 14:38
  • @xorLogic you're right, it's just the binary data. You can use the URL class to decompose the original URL you're calling, but I'm not sure if that's what you're after. – sfdcfox May 24 '18 at 15:30
  • That might work. I'm looking to transfer files between Salesforce and O365. I don't need to preserve the metadata of the files, just the filenames themselves to reference their originals. – xorLogic May 24 '18 at 20:28
