Nanacast is the shopping cart that integrates with everything.
Whenever Drip receives data from Nanacast, we will automatically add the customer as a subscriber (if they are not already in your account) and record and event for that subscriber in Drip.
Register your Drip webhook in with Nanacast
Go to Settings > Integrations > select Nanacast.
Set up automation
In your workflows or basic rules, set up a trigger with Nanacast as the provider, then select the event you'd like to use to trigger the rest of your automation steps.
