Skip to contents

[Stable]

This function will allow you to download an attachment to disk based on the attachment body, file name, and path.

Usage

sf_download_attachment(
  body,
  name = NULL,
  sf_id = NULL,
  object_name = c("Attachment", "Document"),
  path = "."
)

Arguments

body

character; a URL path to the body of the attachment in Salesforce, typically retrieved by sf_query on the Attachment object. Alternatively, you can specify the Salesforce Id of the Attachment.

name

character; the name of the file you would like to save the content to. Note that you should include the file extension in this name and if this argument is left NULL, then a query will be made to determine the name and file extension needed. This process may result in a slower download process, so attempt to provide the body and name arguments whenever possible for the best performance.

sf_id

character; a Salesforce generated Id that uniquely identifies a record.

object_name

character; the name of the Salesforce object that the function is operating against (e.g. "Account", "Contact", "CustomObject__c").

path

character; a directory path where to create file, defaults to the current directory.

Value

character; invisibly return the file path of the downloaded content
