Public API

By SplashSend Free on every planWorks with anything that can send a web request

Make an API key and your own code can add people, orders, events and products, read your lists and keep data sets up to date.

How it works

Once you're in, you'll find it in Apps in SplashSend.

What it does

Keys that do one job

Choose what each key may do, so a key for a sign-up form can only add people.

Every endpoint documented

The API reference lists every endpoint with an example.
