How to programmatically relate/unrelate an asset to another asset or content fragment?

[P_V_Nair]

Hi,

Does someone have any sample code on how we can programmatically  relate/unrelate an asset to another asset or content fragment?

Basically looking for the highlighted OOB functionality that can be done programmatically instead of manual. I have a process to create QR code using Content fragment. So looking on options to relate them somehow, so that users can navigate to the right CF's which created it, by a link on it.

@P_V_Nair I think the AssetRelation API should be the one that you are looking for.

You have an option to relate and unrelate assets using this one.
