# Overview

SeedLink is a unified API for cannabis seed-to-sale compliance. One integration covers Metrc, BioTrack, and every state-system layered on top.

You link your users to their state-system account once. From there you read and write facilities, packages, plants, harvests, transfers, sales, and lab results through a single, normalized API.

## How it all fits together

Your users link their compliance accounts through the Connect SDK, a drop-in widget. SeedLink encrypts and stores their credentials, then proxies normalized API calls to the upstream system on their behalf.
