UI/iFrame integrations
Getting started


iFrame integrations

You can develop your own integration that is injected into Missive with an iframe that can interact with our application via a JavaScript library.


Include this script in your integration page. Check out the JavaScript API.

<script src="https://integrations.missiveapp.com/missive.js"></script>


For your convenience, we also provide a stylesheet for you to include if you want your integration to match our styles. Not only does it accelerate development, it will also make your integration support all of our themes by default. Check out our CSS styleguide.

https is required when adding a custom integration to Missive. During development, we suggest using a tool like Caddy or Ngrok to create a secure tunnel to your local development server.
