I have created a FormAssembly form that modifies an existing SFDC Lead record based on matching email address. The form works great, but I would like to add a "Resume" field to it, so that the Lead could attach a file for his or her resume.
However, I don't know how to set up the mapping in FormAssembly. It looks like a field is necessary to link it to the parent object, but I don't know how to get that data into the form. I tried passing tfa_LeadID from the previous form, which saved the lead record, but it came up empty. (I tried both with the background processor and the interactive one.)
Check out our documentation here: http://www3.formassembly.com/blog/support-documentation/connectors-documentation/salesforce-documentation/how-to-setup-your-salesforce-connector/ Especially the sections on 'creating dependent objects' and 'file uploads and attachments'.
What you want to do is map 'lookup' - 'lead' ---> 'attachment' - 'parentId' in your connector.
