API Overview
The mailfloss email verification API allows you to add email verification to any part of your software, ideal for signup, registration, onboarding, and other points of entry.
You will need an API key and an account with mailfloss to use the API. The API key can be generated inside of the mailfloss dashboard.
Make API calls on the server-side only
The API is not suitable for use in client-side scripts (e.g. React, Angular, Vue, jQuery, and other Javascript frameworks) because our verification endpoints do not allow cross-domain requests. Using it directly in the browser would require exposing sensitive API credentials giving anyone access to your account. Please make all requests server-side.
