Overview

In SignatureAPI, signed documents are called Deliverables. A deliverable is generated automatically once all recipients have signed an envelope. You can see an example here. Deliverables are available for download in PDF format. In many cases, you’ll want to save them to a specific folder—such as SharePoint or OneDrive—for compliance, auditing, or internal record-keeping. This guide shows how to use Microsoft Power Automate and SignatureAPI to:
  • Trigger a flow when a deliverable is generated.
  • Save the signed PDF to SharePoint.
  • Send a notification email with the file attached.
This example uses SharePoint Online, but the same steps work with OneDrive, Dropbox, Google Drive, or other file storage systems.
If you want to only trigger this flow for some envelopes (not all in your account), learn how to filter triggers

​
Creating the Envelope

This guide assumes you already have a flow that sends documents for signature using the “Create an envelope” action from the SignatureAPI connector. No changes are needed in the envelope setup. The steps below focus on what happens after the document is signed.

​
Trigger the Flow When a Deliverable Is Generated

First, create a flow that starts when a deliverable is ready.
  1. Go to Power Automate and choose Automated Cloud Flow.
  2. Name your flow and select the trigger “When a deliverable is generated” from the SignatureAPI connector.
Trigger
This trigger runs when a signed document is available for download.

​
Save the Deliverable to SharePoint

Next, add steps to retrieve the file and store it in SharePoint.
  1. Add the “Get a Deliverable” action.
  2. Use dynamic content to select the Deliverable ID from the trigger.
Get deliverable
  1. Add the “Create file” action from the SharePoint connector.
  2. Set the Site Address and Folder Path.
  3. Set the File Name (use a .pdf extension).
  4. Use File Content from the deliverable.
Save file
This step saves the signed document in your SharePoint folder.

​
Send a Notification Email

Now send an email with the signed PDF attached.
  1. Add the “Send an email” action from the Outlook connector.
  2. In the “To” field, enter the department’s email address.
  3. Attach the deliverable using File Content from the Get a Deliverable action.
  4. Set the filename (make sure to include .pdf).
Send email
This lets the team know the signed document has been saved and is available for review.

​
Result

This flow will:
  • Trigger when a deliverable is generated.
  • Save the signed PDF to SharePoint.
  • Send a notification email with the file attached.
This automation reduces manual work and helps ensure signed documents are stored and shared consistently.

​
Test Your Automation

Test the full workflow:
  1. Save your Power Automate flow.
  2. Create and sign a new envelope.
  3. Check that the email arrives and the file is saved to SharePoint.
