Introduction to Code

Code is Final's developer platform for building custom extensions — add-ons that extend Final POS with your own features. Where the rest of Final lets you run and build your store, Code lets you go further: add your own screens, data, and logic to the platform. It's made for organizations, agencies, and developers.

What you can build

An extension brings a few building blocks together:

• Surfaces — the places your extension's UI appears inside Final. You choose which surfaces an extension activates — for example, in checkout, the back office, or the builder.

• Custom tables — structured data for your extension. Define tables and fields to store the information it needs.

• Hooks and interceptors — the custom logic your extension registers so it can respond to what happens in the store.

• Access and details — set who can use the extension, add its details and images, and set pricing for it.

Together, these let you package a custom capability once and plug it into Final wherever your team works.

Who Code is for

Code is built for organizations, agencies, and developers — teams that want to tailor Final POS beyond what's built in, whether for their own business or for the companies they manage.

How Code fits with Final

Code is part of the Final POS Tool Suite. Extensions you build plug into the rest of Final — the point of sale, the Merchant Hub back office, and the builder — so your custom features show up right where they're used. Ready-made extensions also appear for merchants to install; to see that side, see the Extensions marketplace.

Getting started

Code is a web app you sign into with your Final account. From there you create an extension, choose its surfaces, add any custom tables and hooks or interceptors it needs, set who can use it, and publish.
