Extract data fields from a document and forward the extracted data to REST API URL on submission

I wanted to see if I can do the following with Adobe Sign product.

1. Define a template with a bunch of form data fields with validations.
2. Send the template to a recipient.
3. Once the recipient fills in the document and submits, the document to be received by sender and
4. The filled in data by the sender to be forwarded to a REST API URL where another system processes the data and stores the data in a custom database.

I see that the first 3 steps can be achieved after going through the Sign product tutorials. However, I wanted to check if the task listed in 4th bullet point is achievable or not.

Any help is highly appreciated.

Thanks
