Sending large attachments to external system

Hi,

I am sending a large attachment from salesforce to an external system. While sending the attachments I am facing some issue, I am not able to send attachments size is greater than 12 MB, is there any possibility to send the attachments 12 MB?

Please let me know how to achieve this.

Thanks,
Vijay

Hi Vijay,

That's not possible becuase apex has a heap size limit of 12 mb per transaction. So if you a try to send a data larger than that size your transaction will fail. You can look for workarounds like compressing the size of your attachment and then send it over.

Hope that helps !

Hi Vijay,

Yes, there is a limit from salesforce side for sending large size attachment.You can overcome this limit by using 3rd party storage server for storing the file content as well as sending them over the email with large size attachment.

Cloud Drop is One such App that is somewhat following the same logic in order to store any number and size of files that can be associated with any salesforce object with Rackspace server.It also allows the user to send very large size file as an attachment to particular contact/lead record.

Please check the following link for more information:

Mark this as solved if the information helps.

Nagendra.

Based on what I have found there is not any solution or workaround when you reach the heap limit (12 MB). In my case, I need to move some content from Salesforce to a Content Management solution since those attachments are coming in an email and we know the source email address  I have created a Microsoft Flow so the attachment is moved via API to the content management and the email is saved in Salesforce. On the other hand, I was in touch with a guy from Mulesoft and it seems they have a solution but I did not try that.

No possibily you will not be able to send more than 12 MB. We had similar case and we end up sending large files from Salesforce to java to external system. By which we were able to send more than 1 GB files. However I do not recommend this solution.
