Client API
You can use MailCup.net Client API to bring data from your app or website into MailCup.net, add new or update existing contacts, trigger event-based campaigns, and more.
MailCup.net's API is based on simple HTTP POST. Use the API to integrate MailCup.net programmatically with your website or application. We're working to include more APIs.
This API does not require authentication and can be used client side. You'll only need your MailCup.net account ID.
Get your account ID
If you don't have a MailCup.net account already, you'll need to create one in order to use the Client API. Navigate to the general settings of your account and copy the API KEY
