What Signority API is
Signority API connects third-party integrations to Signority's eSignature and document workflow service through a RESTful API. Signing options include electronic signatures, templates, LinkSign, Bulksign, in-person signing, and witness signing. Its 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 service operates in Amazon Web Services clustered data centers in Canada, and core customer documents stay in Canada. Monthly plans include 10 document packages, and unused monthly packages do not roll over. Paid plans also offer online integrations with over 700 apps at no extra cost. Invited signers and viewers do not need to pay or create accounts. The Free plan follows the trial; Individual costs $12 a month, Standard Team 28.00 USD, and Advanced 55.00 USD. Support is available Monday through Friday, 9am–6pm EST.
