Navigating client authentication with PSPDFKit Server

PSPDFKit Server has been deprecated and replaced by Document Engine. To migrate to Document Engine and unlock advanced document processing capabilities, refer to our migration guide. Learn more about these enhancements on our blog.

PSPDFKit Server uses the JSON Web Token (JWT) format for authentication. Your backend signs a JWT asserting that the holder of the token is allowed to access a given document. Next, it passes the JWT to your client apps that use PSPDFKit for Android, iOS, and Web. Your app then passes its token to PSPDFKit Server to prove it has access to the claimed document.

The JSON Web Token (JWT) is signed with a private key on your server and verified with the public key on PSPDFKit Server.
