Box enables you to add multiple documents to a signature request. Each file remains a separate document with a separate header, but the signer will see them in a continuous flow.To see the flow for a single document, please refer to Sending a document for signature.Uploading multiple files to one signature request is supported for the following flows: Request Signature or Only Me.
To use templates you need to share all files in a template to avoid permissions issues. Batch Send, Ready Sign-Links, and template tags are also supported.
