Client API
You can use FlipMail.org Client API to bring data from your app or website into FlipMail.org, add new or update existing contacts, trigger event-based campaigns, and more.
FlipMail.org's API is based on simple HTTP POST. Use the API to integrate FlipMail.org 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 FlipMail.org account ID.
Get your account ID
If you don't have a FlipMail.org 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
