# Intro (read this first!) Welcome to Winter's Platform API! **The problem** was there were a lot of no-code NFT creation platforms and launchpads that were interested in integrating Winter's checkout for their businesses. They had 10+ launches a day and all integrations were manual through our dashboard. Now, we offer a way to create checkout's at scale via our API - everything can now be done programmatically! **Things to note:** A Winter checkout is predicated on a project ID -- the project ID is how Winter knows what UI to display and which NFTs to mint. The platform API gives you, a Winter user, a way to create and update projects. Given a project ID, you can access your checkout as follows: * Livemode: [https://checkout.usewinter.com/?projectId={PROJECT\_ID}](https://checkout.usewinter.com/?projectId=666) * Testmode: [https://sandbox-winter-checkout.onrender.com/?projectId={PROJECT\_ID}](https://sandbox-winter-checkout.onrender.com/?projectId=98) ## Prerequisites * Get an API key from the Winter team! * Have your smart contract and project info ready -- let's have some fun! You can use [/createProject](/platform-api/createproject.md) and [/updateProject](broken://pages/rQTPPBR08E2MDu7uZY0K) to make project IDs. ## --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
