We were using APM APIs to create alerts in APM. But suddenly it stopped working properly and it seems like an additional cookie DXSESSION has been introduced along with the change of the DLID in alert channels.
Without DXSESSION cookie it does create alert but without notification channel.
This cookie is combination of token and return token encrypted in base64, which seems we can't generate using API call.
Can you please look into that and let us know the procedure to generate that DXSESSION cookie and is it required for all the APIs?
