Suman Kuch How can we decode large String to blob (EncodingUtil.base64Decode)?
Hi,
We are replacing native functionality of Attachments to upload files to "Box"external storage using Rest API, I was able to upload small files upto 5MB but when trying to upload big files I get the error in Apex code (not even going to box)
Please advice how can we ignore the size of the file? We may have to upload 10MB files sometimes, please advice
Thanks,

System.StringException: String length exceeds maximum: 6000000This is occurig when trying to decoding ( base64Decode ) from String blob before Rest API call, please check the code
String bodyEncoded = EncodingUtil.base64Encode(fileBody);
Blob bodyBlob = null;
String last4Bytes = bodyEncoded.substring(bodyEncoded.length()-4,bodyEncoded.length());
// GW: replacement section to get rid of padding without corrupting data
if(last4Bytes.endsWith('==')) {
last4Bytes = last4Bytes.substring(0,2) + '0K';
bodyEncoded = bodyEncoded.substring(0,bodyEncoded.length()-4) + last4Bytes;
String footerEncoded = EncodingUtil.base64Encode(Blob.valueOf(footer));
bodyBlob = EncodingUtil.base64Decode(headerEncoded+bodyEncoded+footerEncoded); //Here its failing
}else if(last4Bytes.endsWith('=')){
last4Bytes = last4Bytes.substring(0,3) + 'N';
bodyEncoded = bodyEncoded.substring(0,bodyEncoded.length()-4) + last4Bytes;
footer = '\n' + footer;
String footerEncoded = EncodingUtil.base64Encode(Blob.valueOf(footer));
bodyBlob = EncodingUtil.base64Decode(headerEncoded+bodyEncoded+footerEncoded);
}else{
footer = '\r\n' + footer;
String footerEncoded = EncodingUtil.base64Encode(Blob.valueOf(footer));
bodyBlob = EncodingUtil.base64Decode(headerEncoded+bodyEncoded+footerEncoded);
}
Error is triggering at "bodyBlob = EncodingUtil.base64Decode(headerEncoded+bodyEncoded+footerEncoded);" this line.Please advice how can we ignore the size of the file? We may have to upload 10MB files sometimes, please advice

Apex has a limit to keep the value up to 6 MB, so it can't cross the value else it will throw the exception.
One option would be to create a heroku app with a single endpoint that takes the attachment Id. The endpoint can then retrieve the attachment and then upload it to the 3rd party server.
Please refer below link for the same.
