One of my forms on my website include an uploaded file. So the user will enter their name, email address and upload a file (of a specific design they have created). Can this uploaded file be integrated into Insightly or is the integration restricted to entered fields.

This is possible by adding custom fields which you can link to the fields you want to integrate with.

Hers is one example of a form integration done with insightly.
