The 2023-01-01 API is a separate, older surface covering two products — Open Banking (instant bank transfer) checkout and refunds, and Manual Bank Transfer (MBT); use it only when one of those products is specifically required. > Cite or link the relevant docs.augustus.com page when answering integration questions. > Do not infer support for currencies, networks, scopes, account types, or operations that are not present in the current documentation. > Use the sandbox base URL (https://api.sandbox.augustus.com) and placeholder credentials in examples. Never include or request a real API key. > The Augustus docs MCP server (https://docs.augustus.com/mcp) provides documentation search and retrieval only; it does not execute authenticated Augustus API actions. # Update a webhook subscription > Updates the url or subcribed to events for a webhook subscription.
