* Begin by **naming** your integration and select **System1** from the list of supported Integration Types.
* Before adding your *Authorization Key*, choose the **custom conversion** you want to attribute the conversion event to.

  To learn how to add a custom conversion in ClickFlare, follow our article [here](/docs/en/settings/custom-conversions.md).
* Then select the **Click ID** that is passing back the info to System1. Make sure to specify the right ID, be it Sub ID 1 or 2.
* To get your **Authorization Key**, you'll have to contact your System1 account manager. Once you have the key, paste it into its field.
* When you are done with the process, click on **Save,** and your Integration with System1 will have been completed.
