How to decode attachement body from base64 while using Async process Salesforce to .Net

HI All,

I am getting some issue my integration process, My senario is We are fetching the attachments from Salesforce with the help of Asynchronous process (Rest) api and adding all the files to .Dll file. But its Showing Error for Body fied Like 'Base64 format not supported'. How can we decode this Body content and how to add to dll file .
Please help Us.
Thanks

Hi Shiva,

The API sends and receives the binary file attachment data encoded as a base64Binary data type. Prior to creating a record, client applications must encode the binary attachment data as base64. Upon receiving a response, client applications must decode the base64 data to binary (this conversion is usually handled for you by the SOAP client).



The difficult part is uploading an attachment to match Salesforce's specific multipart/form-data template. Without going into the exhausing details, the only I found to do this was to manually build the HTTP request body, and put the entire body in an ArrayBuffer, which the browser will not UTF-8 encode. Can you please try the below link and it should help you
