Simple workflow (with
electronic signature)
Overview
For the sample workflow, a PDF
document will be sent to SigningHub for manual signing.
The API will be used to send the
document to SigningHub and configure the workflow. The Signer will
then electronically sign the document by logging into SigningHub and
manually signing the document.
An electronic signature is an ideal
way to get users to quickly and easily sign documents online.
For a discussion on the difference
between electronic signatures and digital signatures see the LAWtrust
article on the differences between electronic and digital
signatures.
Sample code
The sample code can be downloaded here.
Download the accompanying
sample code documentation.
Prerequisites
For electronic signatures there are
no prerequisites for the Signer to register on SigningHub.
Use Case
Electronic signatures are commonly
used to sign documents like invoices, memos, indemnity forms, etc.
This use case simulates a
third-party that generates a PDF document and then send it to
SigningHub for signing.
For example, a bank requires a
user’s consent to do a credit check. They generate the form and
send it to SigningHub. SigningHub requests the Signer to sign. After
the Signer is done, the signed document is returned to the bank’s
workflow system.
Process flow

At a high level, the sample code
will perform the following steps:
-
Prepare the workflow.
-
Share the document.
-
SigningHub sends email
notification to Signer.
-
Signer logs into SigningHub and
electronically signs the document.
-
Third-party application checks
the document status.
-
Third-party application
downloads the signed document.
-
Third-party downloads the
forensic Workflow Evidence report.
-
Deletes the document.
