Assinafy review
A practical e-signature service for teams embedding signing through an API.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Assinafy is a cloud-based electronic-signature service for individuals, businesses, and software companies. It supports uploading or creating documents, adding multiple signers, sending requests by email or SMS, tracking signing activity, downloading completed PDFs, and retaining documents in cloud storage. Its REST API, sandbox and production environments, webhooks, and Postman collection make it especially relevant to teams that want to embed signing into a website, app, or business system. It is less suited to buyers looking primarily for a broad catalog of ready-made integrations.
The API is the product’s clearest differentiator for software teams: it can create, send, and manage documents, with webhook events and JSON responses. On the signing side, teams can set signer order, reuse document templates, review audit reports and signing history, and send documents in batches. That combination covers common workflow needs without requiring a separate signing process for each recipient. The published feature set describes a focused signing tool rather than a wider document-management suite.
Assinafy has a free Basic plan limited to 10 documents per month. Basic includes email-based signing, opening and delivery notifications, 90-day document backup, and a free API. Standard adds unlimited users and signers, unlimited templates, 180-day backup, and specialist support; Pro adds company branding, signer event history, and unlimited backup. Enterprise is customizable and includes technical specialist support, priority service, and a consultative account manager. Choose Assinafy if API access and core signing workflows are priorities; look elsewhere if you need integrations beyond its API-oriented ecosystem or a free tier for higher document volume.
