# Tiptop > Tiptop (Tiptop Labs, founded by Postmates co-founder Bastian Lehmann, backed by a16z) is a payments company whose product lets shoppers trade in items they own for instant credit at checkout, alongside pay-over-time options. Merchants integrate via a Shopify payments app, Salesforce Commerce Cloud cartridge, Magento 2 module, or a Direct API built on the tiptop.js browser library plus three server-side order-management endpoints authenticated with an api-key header. Note: as of July 2026 tiptop.com redirects to mother.ai (Mother Computer Inc.); the developer docs, API hosts, and packages remain live. This file was generated by API Evangelist from the public catalog for this provider (Tiptop publishes no llms.txt of its own; docs.tiptop.com/llms.txt returns 404). ## Docs - [Tiptop Docs](https://docs.tiptop.com/): developer documentation portal - [How the Direct API integration works](https://docs.tiptop.com/direct/how-it-works/) - [Direct integration — get started](https://docs.tiptop.com/direct/get-started/) - [API keys](https://docs.tiptop.com/api-keys/): four keys per account — public/private pairs for test (sandbox) and live modes - [Tiptop-JS reference](https://docs.tiptop.com/direct/tiptop-js-reference/overview/): loader script at https://cdn.tiptop.com/js/v1/tiptop.js - [Open Tiptop checkout](https://docs.tiptop.com/direct/tiptop-js-reference/tiptop-checkout/): tiptop.checkout(...).open(), callbacks onFail/onCancel/onSuccess/onOpen/onValidationError ## APIs Production API host: https://api.tiptop.com/ (staging: https://api-stage.tiptop.com/).
