Our verdict on Signority API
Signority API provides programmatic access to electronic-signature and document workflows for businesses and organizations integrating signing into applications. Developers can create and send documents, manage folders, use reusable templates, collect signatures sequentially or in parallel, and receive callbacks for document and finalized-file notifications. It supports web and API access, with API-key or basic authentication and sample code for several programming languages.
The published plans show a freemium structure, with accounts moving to Free after the 14-day trial. Individual costs $12 per month for 10 document packages, while Standard Team costs $28 per month and adds a sandbox environment plus team and user management. Advanced costs $55 per month and adds Batch Sign and Template Overlay. Annual options include Individual at $129 for 120 document packages, Standard Team at $302.40 with team features and a sandbox, and Advanced at $594 with Batch Sign and Template Overlay. A Custom plan offers enterprise features.
Its strongest fit is for teams that need several signer-authentication options, reusable API templates, bulk signing, and workflow notifications without starting at a high monthly price. Integrations with Microsoft SharePoint, Office 365, Amazon S3, and SFTP also support document-centric environments. The API supports testing and sandbox environments, although the sandbox is listed with Standard Team rather than Individual. Teams specifically requiring verified embedded signing should evaluate alternatives, while organizations seeking automated signing, storage connections, and flexible authentication modes should consider Signority API.
