In their own words
Signority API
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; the service also supports webhooks and signing-order options. 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#, while 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 remain in Canada. Monthly paid plans include 10 document packages, and unused monthly packages do not carry over. Individual costs $12 a month, Standard Team $28 a month, and Advanced $55 a month; additional document prices vary by plan. Paid plans offer online integrations with over 700 apps at no extra cost. Invited signers and viewers need neither an account nor payment.
