Add our tools to your products and applications
Our two APIs enable you to integrate our industry-leading tools into your own products and applications.
Reseller API
White label our testing services and resell them to your customers—from $499/month.
Our Reseller API is optimized for high volume usage by providing a direct connection to our testing grid. It is fully licensed for resale, so you can sell our testing services direct to your own customers under your own brand. The Reseller API is covered by our Service Level Agreement and we provide full telephone and priority email support (including deep technical and code support).

Customer API
Build applications that use your existing Litmus account—from $79/month.
Our Customer API allows you to control your Litmus account via the API. This is ideal for companies seeking to build applications that integrate Litmus' testing tools into their internal processes. Note that this API isn't licensed for resale, and we can only provide limited technical support by email. However, you can get started right away simply using your own Litmus account.

First sign up for a Litmus account, then review our Customer API documentation.
