As soon as you start identifying your website users you can start designing your own automation workflow. You will find that among the available trigger types there is one titled "When custom event is recorded". As its name implies, this trigger reacts by starting your automation when a custom event is passed via custom code website tracking on a website that you manage.
There are three parameters that you need to define on this type of trigger:
1. You need to choose whether the automation will be triggered every time that someone triggers this event, or whether it will be triggered on the first event only.
2. The second parameter you need to define is the website(s) where the page browse needs to take place in order to trigger your automation.
You can find a list of the websites that you manage on the drop-down menu, as well as an option to track all of your websites. Choosing a specific one means that events from all other websites will be ignored. After you are done, click on the Save button to have your trigger ready and waiting inside your workflow.
3. The third and final parameter that you need to define is the name of your event.
Only the event you selected will trigger the automation. Please make sure that you have sent data for this event first, in order to be able to select it here.
This is the starting point for creating an automation workflow that will be triggered whenever a custom event is recorded on the website you have chosen. Learning how the available Conditional / Control steps and the available Actions work, will help you finalize your design.
