You can think about connecting flows to broadcasts in the same way as How to trigger flows from widgets, the only difference is that the trigger is different.
You can think about it like this:
In the example below, the first WhatsApp message you see will be the first interaction that contacts will have with this campaign. Afterward, it depends on the buttons they click!
We create our flow first, then the rest of our campaign.
First, go to “Flows” and click “Create flow”
You will start with a new flow, and then select broadcast trigger:
Then, create the rest of your flow as you normally would, and hit “Publish!”
Make sure the flow is “ON”
