CLM Custom alerts

Hi all,

for a customer project we need to create custom alerts at a specific time (filled in in a custom field).

Is there any possibility (APIs) to create alerts in CLM and in the Contract calendar?

If this doesn't work we will try to create a schedule item out of a script which will have the custom field value as start date.

Is there any possibility (APIs) to create Schedule items (in Master agreements) out of a script?

Thanks and regards,

Özlem
