Authentication & Security
Security is paramount when handling sensitive business documents. The AbroadSign API employs multiple layers of authentication and encryption to protect your data. All API communications use TLS 1.3 encryption, and we support OAuth 2.0 for secure authorization. API keys can be scoped to specific permissions, allowing you to implement the principle of least privilege in your integrations.
For enterprise deployments, we offer additional security features including IP whitelisting, certificate-based authentication, and detailed access logging. Our security infrastructure is designed to meet the requirements of regulated industries including banking, healthcare, and government.
