To create a flow, you will need to select all the sites from the dropdown list.
You can select multiple sites at a time to create a data flow on several sites. However, you will receive one URL per site to call the API.
The events universe has unique rules that apply to it. If you select multiple sites at once, you will not see variables unique to each site show up in the list of available dimensions as they can change from one site to the other. In order to create a event flow with site indicators, you will need to create it one site at a time.
During the creation of your flows you can test your links before saving your configuration.
If you have selected multiple sites, you have the possibility to select the site on which you test the link.
Once you have selected the dimensions to extract, click on “Copy the URL ”. This will generate one url per selected site.
