You can use Zapier to automatically save a signed agreement PDF to Google Drive whenever a Common Paper agreement is completed. Once set up, every newly signed agreement is downloaded from Common Paper and stored in your Drive - no manual steps required.

NOTE: This Zap requires a paid Zapier plan. Webhooks by Zapier is a premium app and is not available on free Zapier accounts.

Before building this Zap, you'll need:

Create a new Zap and choose Webhooks by Zapier as the trigger app. Select Catch Hook as the trigger event and click Continue.

Zapier will generate a webhook URL. Copy that URL and add it as a notification webhook in Common Paper. For instructions on how to do this, see Notification webhooks.

Once the webhook is active, complete a test agreement in Common Paper so Zapier can receive a sample event. Use that sample to continue configuring the Zap.

Add a Filter by Zapier step. Configure the condition as follows:

This ensures the Zap only continues when an agreement is fully signed. Events for other status changes - like "sent" or "viewed" - will be ignored.

Add a Webhooks by Zapier action step and select GET as the action event.

In the URL field, type https://api.commonpaper.com/v1/agreements/, then use Zapier's variable picker to insert the Agreement Id field from Step 1, then type /download_pdf after it. The completed URL should look like this:

https://api.commonpaper.com/v1/agreements/{Agreement Id}/download_pdf

Under Headers, add one entry:

Replace YOUR_API_KEY with your API key from Settings > API Keys in Common Paper. Leave all other settings at their defaults (Send As JSON set to No, Unflatten set to Yes).

Add a Google Drive action step and select Upload File as the action event. Configure the step:

Turn on your Zap. Going forward, every time an agreement is completed in Common Paper, the signed PDF will be saved automatically to your Google Drive.
