DRM License Issuance Integration

To play the packaged content on a client device, you must acquire a DRM license from that device. Licensing can be done in two ways: callback and token. Please refer to the table below for the differences and advantages and disadvantages of the two methods.

Integration type Description Pros Cons
Callback The major implementation is between PallyCon license server and your back-end system. Smaller implementation work on the client side. Better control of license issuance and security License acquisition may take longer than token model due to the additional communication via callback.
Token The major implementation is between your back-end system and client apps. Better performance on license issuance because the process is simpler than callback type. More implementation work needed in client app. You need to manage the generated token securely on your own.

The callback type integration method is not recommended because delays or errors may occur depending on the situation of the customer’s system. Please use the token method instead, and contact us if you want the callback method for a specific reason.
