For the Confirmit Horizons platform, the Dapresy solution has 3 types of integrations. In case you need to set up a new integration, please use V2 or V3. V2 and V3 supports stacked data. V3 is the version which will be developed further in the future.

V1 will be phased out over time

Here you can find the instructions how to connect Dapresy to Confirmit (still available for both v1, v2 or V3).
