What is API

In terms of definition, APIs connect pieces of software together. They ‘glue’ together any required information components around a system and are often ‘released’ to third-party programmers who will want to connect application elements and services together.

For browsers extension development - API is a way to communicate between extension and customer's server - e.g get information about deals, stores and offers or send any kind of statistics


Array request

Some methods should have the same response for all users (logged or not)

User info

Some method's answers should depend on user's auth state

User login

You need to set a special cookie on your site when user is logged (without HTTPOnly and secure flags). Then extension will use this cookie in API requests.

User logout

When user is logout, you can just remove this cookie from user's browser.


If you want to update extension in any store, use your developer dashboard:

Distribution on your own

Firefox and Chrome extensions can be distributed using inline installation.

It is more convenient for users to install extension directly from your site without redirect to store.

If you are going to use inline instalization for Firefox, you need to create two instances on you server: 1) Update-file URL - it's location where you are going to store update-file (e.g http://www.example.com/path/update.firefox.xml); 2)Build URL - path to fresh build of your extension (e.g you can store it on your server - http://example.com/path/to/build/extension.xpi or you can submit your extension to the Mozilla Addons and set link like this https://addons.mozilla.org/firefox/downloads/latest/{addon-name}/{addon_id}-latest.xpi);

In case inline instalization for Chrome you still need to submit your extension to Chrome Web Store, but you can choose to not list it and use inline instalization insted. Just set next inputs in Developer Dashboard: Websites - to your site url, Inline install to "This item uses inline install" and Visibility options to "Unlisted".
