Our API offers a host of functionality to help our creators automate a bunch of tasks to help make their lives as easy as possible and developers build apps for our ever-growing Kit App Store.

As long as the authenticated account’s plan is eligible for use with the API, apps and legacy integrations, you will be able to create and send broadcasts to your subscribers, manage your email list through tags and custom fields, import purchase data from your favourite e-commerce platforms and much, much more.

If you are a third party developer, you can use the Kit API to link together or build on top of the Kit platform. Then, once your app is complete, you will be able to publish it to the thousands of creators using our platform today.
