The Sertifi API

Integrate existing applications quickly, easily, and securely.

Using the Sertifi API, third-party partners and customers can quickly integrate the Sertifi Agreement and Authorizations Platforms into their existing solutions.

The Sertifi API allows customers to focus on what they do best while ensuring secure finalization of the business process without the need to build on their own and invest their own technical resources.

By integrating the Sertifi API, companies can quickly begin receiving secure and compliant agreements much faster than building these tools on their own. Companies can also trust that they are receiving the most up-to-date compliance and security by partnering with Sertifi, who has over a decade of experience in this space.

By integrating Sertifi’s API, companies can finalize agreements while reducing manual processes and saving valuable time and resources.


Sertifi’s API is a web service that enables you to quickly, easily, and securely integrate into existing applications. Transactions are defined on the host application, allowing the workflow to be defined by the developer. This lets you rapidly integrate the service to send, manage, track and retrieve completed transactions. Our web portal solution provides administrative interfaces that allow you to configure settings, manage users, and view and track transactions. For transaction status, we provide real-time web service push or pull methods.
