Signority API
What Signority API is
Signority API connects third-party integrations to Signority's eSignature and document workflow service. Its RESTful API provides the functionality of the online application, with signing options that include electronic signatures, templates, LinkSign, Bulksign, in-person signing, and witness signing. Digital signatures use GlobalSign DSS for PKI-based signing and certificate storage. Developers can use test and sandbox environments, but documents signed there are not legally binding. Sample code is available for Python, Java, and C#; JavaScript setup is listed as coming soon. API authentication uses an account email and password or an API key, with authentication data encrypted using SSL. The platform operates in clustered AWS data centers in Canada, and core customer documents remain in Canada. Monthly plans include 10 document packages, and unused monthly packages do not carry over. Paid plans start at $12/mo; the Free plan follows the trial. Online integrations with over 700 apps are offered through paid plans at no extra cost. Invited signers and viewers do not need an account or payment.
