I have checked out many helpful discussions here in regards to file upload with Marketo forms with encode Base64, however I do see that size limits may become an issue within Marketo.
Essentially we want potential leads to be able to upload a file (.docx, .pdf only) and we would need to push this file into SalesForce.
Is there a way we can do this? Thanks in advance.
Not an easy one
One thing is sure: Marketo will not push a file into SFDC. The best you could imagine is either push an encoded blob or a file URL. In both cases, you will need some processing in SFDC to restore a file from the blob or upload the file from the URL.
In anycase, the technique you should use is there: Re: HOWTO: Attach images to a Forms 2.0 form post
I would now use UploadCare -- but again, the file won't get into SFDC directly, though the URL to the file will.
Thanks Greg and Sanford for the insightful information! I think we will end up storing the document in a S3 bucket (since we already have a subscription).
