We've added documentation for the External Authorization integration model, enabling partners to manage user balances in their own systems while settling transactions through a prefunded Master Account.

What's new:

Simplified onboarding — Register users via API without deploying Smart Wallets or on-chain registration
Authorization API reference — Complete contract for the /authorize and /settle endpoints your system must implement
Card transaction handling — How transactions settle against the Master Account and how to handle webhooks
Implementation examples — Code samples in JavaScript, Python, and Go

Who is this for:

Partners who want to:

Maintain their own balance ledger
Apply custom authorization logic per transaction
Avoid per-user on-chain wallet deployment
