Integrations that have been developed using the old API version to not have to be migrated, the v1 resources are still available. When developing new integrations however, make sure to use the new resources. Please also note: that for the new API (all resources without url versioning) the entities might contain changed field names e.g. AlertSource.incidentCreation
=> AlertSource.alertCreation
a few fields were subject to this change our API docs are already reflecting this change, you can find them below.
